[Kamailio-Users] preparing RC3 for kamailio 3.0
by Daniel-Constantin Mierla 14 Dec '09

14 Dec '09

Hello, I plan to release Kamailio 3.0, hopefully today, if no outstanding issue out there. Ending of last week, I managed to get debian packaging working (tested on Ubuntu) using Andrei's new Makefile system, with module groups. If you are aware of issues you want fixed before 3.0RC3, drop an email. This is supposed to be latest RC before full 3.0.0 release. Cheers, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/

[Kamailio-Users] Bflags
by David 14 Dec '09

14 Dec '09

Hey, I am having some issues with NAT and I think the issue is with Bflags. So I have some clarifications : 1. What does the flags column in location contain? 2. What does the cflags column in location contain ? I am guessing that cflags represents the bflags? So if I have a value of 192, does that mean flags 7 and 8 are set ? This confuses me cause I set flags 6 and 7. Do the bflags appear magically in the routing scripts or is there a command that I have to execute for the script to have the bflags? Thanks! David

What to download?
by Antonio Goméz Soto 13 Dec '09

13 Dec '09

Hi, I'm a longtime asterisk user, needing to scale up. I figured it would be smart to use and develop for sip-router, because it'll come out soon. But I've never used one of ser, openser, or siblings, and now I'm confused by the download links on you site. I see kamailio_3.0, master, sr_3.0, stable and unstable top level directories. What should I download? What's the diference between them? Thanks, Antonio

[Kamailio-Users] Rewrite $tU
by David 11 Dec '09

11 Dec '09

Hey, I need to rewrite the $tU variable on a packet before it is relayed. It is ok if the change is only on the relayed packet and the $tU variable change. The important thing is that I modify the To header, it seems that rewritting $tU would be the easiest. I know that user agents do not like this changing, but I am changing it on an intermediary server and when the reply comes back, I change it back to the original value. Thanks! David

Case sensitivity in usrloc "location" table
by Bruce McAlister 10 Dec '09

10 Dec '09

Hi All, I am trying to integrate Kamailio (1.5.2-notls) into our existing database structure using a view for the subscriber table and using the location table to store the registration information. I am successfully able to register a phone using this method. One of our requirements is to set an "outboundproxy" and "outboundproxyport" parameter in the location table for a particular sip account (username). I am trying to do this with the sqlops module. What I have come across though is that when the registration information is saved to the location table the username is stored in lower case. So when my sqlops query is run against the username it does not match. Is there a way to tell the usrloc module to store the username in the same case as it is received? For example, in the subscriber table I have view defined that for my user account returns the following information: ------------- select * from subscriber where username = 'BruceNW9440'; username | domain | password | ha1 | ha1b -------------+---------------+------------+----------------------------------+---------------------------------- BruceNW9440 | 10.10.10.10 | 00minger00 | 1f2d688f65be04a61cab36a1fb3f426a | 6529d45f5c418daf35be7b3dd4a858cb (1 row) ------------- Now, if I check the above against the location table: -------------- select * from location where username = 'BruceNW9440'; 0 rows returned -------------- If I run the same query using "brucenw9440" as the username (lowercase) then the correct information is returned. I have the following log line in my kamailio configuration script: xlog("L_INFO","Username: $au, OutboundProxy: $Ri, OutboundProxyPort: $Rp"); The details of this log appear correct when it is logged: Dec 9 14:21:03 ibis /opt/kamailio/sbin/kamailio[16972]: [ID 197553 local0.info] Username: BruceNW9440, OutboundProxy: 10.10.10.10, OutboundProxyPort: 5060 However, when my sqlopt query is run it does not find a match because of the incorrect case: sql_query("bfl", "UPDATE location SET outboundproxy = '$Ri', outboundproxyport = '$Rp' WHERE username = '$au'", "res"); I've had a read through the usrloc module documentation and I cannot seem to find a reference to any options that will preserve the case. I also cannot find if there is a parameter to save('location') that will preserve the case. I cant seem to find a reference to the save() function on the wiki. I must be missing something small. We have some sip usernames that are case sensitive so any help in being able to resolve this would be greatly appreciated. Thanks Bruce

[Kamailio-Users] Question regarding TM module DNS failover with SRV records
by Nathan Angelacos 10 Dec '09

10 Dec '09

According to the 1.5.x TM module documentation, DNS failover is triggered by a 503 reply or a timeout. When using SRV records, it appears a 503 triggers the failure_route instead. Given: host -t srv _sip._udp.voip.example.net _sip._udp.voip.example.net has SRV record 1 0 5060 fast-server.example.net. _sip._udp.voip.example.net has SRV record 2 0 5060 slow-server.example.net. On an invite to voip.example.net, if fast-server does not respond within "fr_timer" seconds, t_relay fires off a serial branch (t_on_branch is triggered) and the invite goes to slow-server. If fast-server responds with a 503, the t_on_failure route is triggered instead, and the invite is not sent on to slow-server. If its not a bug in the module, does anyone have clues of how to coax the next DNS SRV record out of the t_on_failure route? Or what can be done to get t_relay to consume the 503? Thanks!

[Kamailio-Users] Siremis login page once and again.
by Vicente 10 Dec '09

10 Dec '09

Hello, I've installed siremis 0.9.4 with kamailio 3.0.0rc2 on a test computer and it was working without a problem. But now I'm trying to install it on a server and I can't go beyond the login screen. If I try a wrong password I get the error message. But if I use the right one I'm redirected to the login screen again and again. Both systems are ubuntu Linux with the following differences: Test computer Server Ubuntu 9.10 Ubuntu 8.10 apache 2.2.12 apache2.2.9 PHP 5.2.10 PHP 5.2.6 mysqld 5.1.37 mysqld 5.0.67 The bigger difference that I can see is mysqld version.But I've installed PHPOpenBiz framwork and the demo app creates and populates the demo data base. So it doesn't look like related to this. I've used the apache configuration on the siremis install page to set up apache for both systems. Although on the server there are some previous settings, I've created a new virtual server for siremis. apache logs only show: File does not exist: /var/www/siremis-0.9.4/siremis-web/js/sound.js But this error also appears on the working computer. And doesn't seem to be related with the problem. The log_DEBUG.html on siremis only shows the query to the database. ¿ Is there any log file on siremis that can point to the problem ? ¿ Has anyone else had this problem ? Sorry if I ask something silly but I've been trying to find what I'm doing wrong for two days. Best regards. Vicente.

Perl Module Logging Query
by Bruce McAlister 09 Dec '09

09 Dec '09

Hi All, I have been trying to use the perl module with Kamailio 1.5.3-notls. I have managed to load the module successfully. I have a simple script with a single function that strips the "<" or ">" from a contact header and logs the info, then sets an AVP. Kamailio seems to load the perl module and the script properly, but when it runs I get an error on the logging side of it. I cannot for the life of me see where the error lies. Could one of you guru's out there please cast an eye over my config and see if you can spot something I am missing. My kamailio configuration for perl is as such: ---- loadmodule "perl.so" modparam("perl", "modpath", "/opt/kamailio/lib64/perl") modparam("perl", "filename", "/opt/kamailio/perl-scripts/kamailio-perl.pl") ---- My perl script looks as follows: ---- use OpenSER ; use OpenSER::Message ; sub clean_contact { my $contact_header = shift; log("contact header passed: $contact_header\n"); $contact_header =~ s/^<|>$//g; log("contact header fixed: $contact_header\n"); OpenSER::AVP::add("clnct", "$contact_header"); return 1; } ---- I have the following section in the route logic that calls this function as follows: ---- perl_exec_simple("clean_contact","$ct"); ---- When the perl script executes, it gets to the first log line and dies with the following message: ---- ERROR:core:XS_OpenSER__Message_log: perl error: Can't take log of 0 at /opt/kamailio/perl-scripts/kamailio-perl.pl line 7. ---- I have had a look at the logging.pl script in the sample directory for the perl module, and have tried all the methods shown in the example, but I just cannot seem to get past this particular logging issue. Any tips would be greatly appreciated. Thanks Bruce

[Kamailio-Users] Problem with REGISTER
by Uriel Rozenbaum 09 Dec '09

09 Dec '09

Hello guys, I'm having a strange problem with my Kamailio 1.5.3 when trying to register an Audiocodes Gateway. I'm using authentication for REGISTER messages. The GW sends a REGISTER without credentials, so I do a proxy_challenge. Then the GW sends a REGISTER with credentials but the proxy_authorize is returning -4. I did an NGREP to check the messages and they don't seem malformed, can you tell me if there is something on the functions that might be loosing the Proxy-Authorization header? This happens only with this GW, not if i register a softphone (XLITE). Within route block: ... if (is_method("REGISTER")) { route(11); save("location"); exit(); } ... Route(11): route[11] { # ----- AUTENTICACION DE UN MENSAJE ----- if (!proxy_authorize("", "subscriber")) { switch($retcode) { case -1: xlog("L_INFO", "AUTH: Invalid username\n"); sl_send_reply("403", "Forbidden"); exit; case -2: xlog("L_INFO", "AUTH: Invalid password\n"); sl_send_reply("403", "Forbidden"); exit; case -3: xlog("L_INFO", "AUTH: Nonce ambiguo\n"); break; case -4: xlog("L_INFO", "AUTH: No credentials\n"); break; #default: #xlog("L_INFO", "AUTH: Unknown error\n"); #break; } #xlog("L_DBG", "AUTH: -Data- Auth Username = $au\n"); #xlog("L_DBG", "AUTH: -Data- Domain = $fd\n"); #xlog("L_DBG", "AUTH: -Data- From Username = $fU\n"); proxy_challenge("192.168.200.130","0"); exit; }; xlog("L_INFO", "AUTH: Valid username and credentials\n"); consume_credentials(); } NGREP: # U 10.0.1.200:5060 -> 192.168.200.130:5060 REGISTER sip:192.168.200.130 SIP/2.0.

PerlVDB Usage
by Bruce McAlister 09 Dec '09

09 Dec '09

Hi All, We are looking to integrate SIPRouter/Kamailio into our existing infrastructure. Currently we have a sip proxy and registrar that handles registration and routing. The main issue we have with integrating SIPRouter/Kamailio into our environment is that the table structure for kamailio's tables are vastly different to our existing database tables. We have several application built around our current database structure so I think it is fair to assume that we will be forced to use the existing structures. I had a look at perlvdb which seems to do what I had in plan, where the table structure is transparent to kamailio. so for example, when a registration request comes in and we then authenticate the user and want to save the location, could we use the perlvdb module to intercept the save and manipulate it so that it inserts/updates/reads data from a table structure that is different to what it is expecting? I've been trying to find an example of how to use perlvdb but have been unsucessfull in my google searches and mailing list searches. Does anyone have an example of how to use the perlvdb module? Thanks Bruce

[Serusers] Via: branch tags from SER for CANCELs/BYEs frequently don't match value in the INVITE
by Frank Durda IV 07 Dec '09

07 Dec '09

As you may recall, this is a problem where frequently (well, virtually all of the time) when SER passed a BYE or CANCEL message through, the device receiving such messages from SER would reject them, because the Via: header line that SER added to the BYE or CANCEL message didn't match the one that SER added to the INVITE message sent earlier. I brought this up a couple of times in the list previously. As there was not any response on this point at all, I have done some digging and have a simplified example and analysis of what SER appears to be doing wrong. First, here is an example of the problem occurring. Here are key header lines from the INVITE and a BYE message of a sample call: INVITE INPUT TO SER From: <sip:9715551212@10.11.12.13;isup-oli=62;user=phone>;tag=000a0285+1+9c6d0174+ff665515 To: <sip:3719110000@10.20.30.40;user=phone> Call-ID: 16305237000a0285 CSeq: 252558264 INVITE SER EMITTED THIS INVITE (to called party) Via: SIP/2.0/UDP 66.77.88.99;branch=z9hG4bKe47c.7be033a8ca37f0e8a1c6bfe63b043efe.0 From: <sip:9715551212@10.11.12.13;isup-oli=62;user=phone>;tag=000a0285+1+9c6d0174+ff665515 To: <sip:3719110000@10.20.30.40;user=phone> Call-ID: 16305237000a0285 CSeq: 252558264 INVITE BYE INPUT TO SER (from calling party) Call-ID: 16305237000a0285 From: <sip:9715551212@10.11.12.13;isup-oli=62;user=phone>;tag=000a0285+1+9c6d0174+ff665515 To: <sip:3719110000@10.20.30.40;user=phone>;tag=15358744 CSeq: 252558265 BYE SER EMITTED THIS BYE (to called party) Via: SIP/2.0/UDP 66.77.88.99;branch=z9hG4bKf47c.c79c6922afd022e9b4cdf00110f17fd5.0 Call-ID: 16305237000a0285 From: <sip:9715551212@10.11.12.13;isup-oli=62;user=phone>;tag=000a0285+1+9c6d0174+ff665515 To: <sip:3719110000@10.20.30.40;user=phone>;tag=15358744 CSeq: 252558265 BYE The called switch rejects the BYE with a 481 because top-most Via: in the BYE does not match the one from the INVITE. Here are the two VIAs added by SER that do not match: INVITE Via: SIP/2.0/UDP 66.77.88.99;branch=z9hG4bKe47c.7be033a8ca37f0e8a1c6bfe63b043efe.0 BYE Via: SIP/2.0/UDP 66.77.88.99;branch=z9hG4bKf47c.c79c6922afd022e9b4cdf00110f17fd5.0 A review of how SER constructs the branch=nnnn value reveals where the differences are coming from: #1. e47c vs f47c difference caused by the Cseq: number changing between INVITE and BYE messages. The Cseq: value is supposed to be different in the INVITE and BYE per RFC 3261. The Cseq: should not be used in generating the branch=nnnn value. In this example, the BYE just happened to get the very next sequence number, but it will always be a value other than the sequence number seen in the INVITE. #2. 7be033a8ca37f0e8a1c6bfe63b043efe vs c79c6922afd022e9b4cdf00110f17fd5 is caused by ;tag=15358744 added to BYE To: header line. At minimum, any tags present on the To: and From: header should not be used in generating the branch=nnnn value because of the handling of tags in called-party-BYE situations. Also, there is no requirement in RFC 3261 that the To: nor From: header lines be used in generating the branch=nnnn value at all. Based on what I am seeing, it appears that neither the Cseq: nor the complete To: or From: header lines should have ever been used in constructing a branch=nnnn value, because of the adverse affects on CANCEL and BYE messages. Four things appear to be key to causing the branch=nnnn computation to generate non-compliant results in this example, as well as the case of a CANCEL message sent prior to the completion of the INVITE. (There could be other scenarios.) #1. The Cseq: value of the BYE will be different than the INVITE (per RFC 3261). The Cseq: header line should not ever be used in generation the hash for a branch=nnnn value as it will prevent the branch in BYE from matching the one in the INVITE. #2. If the called party generated the BYE message, the tags on the To: and From: header lines will be exchanged (also per RFC 3261), so the entire To: and From: header line's content cannot be used for generating a hash for a branch=nnnn value that is expected to match earlier messages that had a branch=nnnn value computed prior to the tag swap. #3. If a tag was previously absent on the To:/From:, a BYE from either party will add one. Again, the entire To: and From: header lines cannot be used for generating a hash for a branch=nnnn value that matches earlier messages prior to the addition of any tag. #4. Any deviation in the From: and To: header lines between INVITE and BYE/CANCEL will yield a different branch=nnnn value, even though the parameters of the From: and To: header lines may still be perfectly legal and technically identical. Any deviation may be the result of a sloppy SIP implementation in the calling equipment, but isn't valid grounds for not handling the message correctly. Examples include things like alternate number formats (as in To: sip:8885551212@66.77.88.99:5060 (seen in INVITE) versus To: <sip:8885551212@66.77.88.99:5060> (seen in CANCEL from same calling device), or differences in the amount of whitespace (including trailing whitespace), which is supposed to be ignored in SIP messages but the MD5 generator doesn't appear to know that it should ignore whitespace. Any one or a combination of these items (and possibly others) will cause the current branch=nnnn generation code in SER to generate a different branch=nnnn value and a receiving system who is following RFC 3261 will reject the BYE or CANCEL message that has passed through SER. This is non-compliant behavior. For BYE, you only get into this situation if you are using Record-Route to force the BYE message to pass through SER so that it can tear down the call (unforce_rtp_proxy() and similar actions), but for a CANCEL message, anybody can run into this problem, if syn_branch=0. So, while this defect in the branch=nnnn generation doesn't affect everybody, it still appears to be wrong. Is there by chance a compliant version of char_msg_val() exists that doesn't have these issues? That is, it doesn't use the Cseq: header line, and if it uses the From: or To: header line at all, it computes using only the called/calling digits, and not anything else that may appear on those header lines. I also don't understand why this is being MD5'ed. The RFC only says that the branch must be unique, and there are lots of cheaper has algorithms out there. Thanks for reading this far and thanks in advance for anyone who has fixed this or can come up with a fix.

[Kamailio-Users] Add Reason Header in CANCEL request (forked call)
by heinz huber 07 Dec '09

07 Dec '09

Hi everyone, I've the following question: Is it possible to add a reason header in a CANCEL request? This is helpful in the following scenario: A call gets forked by the proxy (since there are more contacts for one AOR). On the of the SIP-destination-UAs accepts the call and sends a 200 OK to the proxy. The proxy afterwards generates the CANCEL request for all open UAC transactions. In this case it would be helpful to add additional infos, like "Call completed" elsewhere, so that the call is not listed in the "missing calls" list in the destinations UAs. I've found a linke in the tracker on http://sourceforge.net/tracker/?func=detail&aid=2581449&group_id=139143&ati… Has this feature been included in the last official kamailio version, or is it still open. thx && br Andy -- Jetzt kostenlos herunterladen: Internet Explorer 8 und Mozilla Firefox 3.5 - sicherer, schneller und einfacher! http://portal.gmx.net/de/go/atbrowser

Hi, I simply trying to modify URI and FROM headers as follow. tcpdump packet capture shows the values are changed for both URI and FROM headers. However, the syslog only shows the new value for URI and not for FROM header. How can I verify new value in FROM header in the log file? # main request routing logic route { $rU = avp(i:1); $rd = avp(i:2); .... uac_replace_from("$avp(i:3)"); xlog ("fu after perl: $fu"); xlog ("ru after perl: $ru"); ... } Thanks, Rob

[Kamailio-Users] finding out which gw id was used
by Anders 07 Dec '09

07 Dec '09

Hi, I would like to know which gw was used for a call. Right now, it is doing this: sql_query("cb", "select id from gw where ip_addr='$rd'", "rb"); ...in route[1], but that's not good enough, because I have more than one gw with the same IP, so it just takes the first one available. If I could do something like "select id from gw where grp_id='grp_id_from_lcr'" , where grp_id_from_lcr is the the grp_id in the lcr table, which lead to the gw used... then I'd have the right id of the gw, since I use unique numbers for the grp_id in the gw table. How do I do this? Thanks!!

Hi, I am currently integrating an H323 to SIP gateway with Kamailio and trying to route all calls through RTP Proxy. I have a problem where RTP Proxy treats both the incoming H323 gateway call (Caller) and outgoing SIP call (Callee) as the 'caller' in the RTP Proxy syslog. RTP Proxy doesn't assign a 'callee' therefore not able to setup a call (See syslog below). I have configured Kamailio to accept the 'ACK' with SDP and this is working correctly. When I enable H323 Fast connect and the SDP is included in the INVITE, the call connects correctly and is routed through RTP Proxy. I feel the problem is related to RTP Proxy receiving an INVITE from the H323-SIP gateway without SDP. Can anyone explain why RTP Proxy treats both the incoming H323 Gateway call and outgoing SIP call as the 'caller' in the RTP Proxy syslog. How can I make RTP Proxy treat the incoming H323 call as the 'callee'? Thanks, More information below ******************************************************************************* My H323 endpoints use H323 Slow Connect, so when the H323-SIP Gateway delivers the 'INVITE' to Kamailio there is no SDP included in the INVITE. I added a 'onreply_route' to the Kamailio configuration file which handles the 'ACK' with SDP which is working correctly. All of my SIP calls (Signalling + Media) are forced though RTP Proxy and I would like to force all H323-SIP Gateway calls through RTP Proxy. When placing a call from my H323 endpoint to my SIP UA, the RTP Proxy syslog records the incoming and outgoing call, however RTP Proxy states that the ‘callee’ is actually the 'caller'. The RTP Proxy syslog also states that the caller is the caller so there is no 'callee' (see below). In the syslogs both the ‘callee’ and ‘caller’ are recognised as the ‘caller’ so RTP Proxy has no callee to send the traffic back to. When the INVITE is received the ‘callee’ is populated in the syslogs as the ‘caller’. The H323 Gateway call is not recorded until after the ‘ACK’ with SDP is received from the gateway.

Build Error for v3.0.0-rc2 (2009-12-03_3ed668) on Solaris
by Bruce McAlister 03 Dec '09

03 Dec '09

Hi All, I am trying to build Kamailio v3.0.0 RC2 on Solaris 10 (note: *not* OpenSolaris), but I have been faced with a couple issues I hope you can help me with. The first issue has to do with GNU as (/usr/sfw/bin/gas), there appears to be a check somewhere for what I assume to be the version number of the GNU assembler. When the make is running "/usr/sfw/bin/gas -V" it just hangs at this point with the following output from make: ---- make prefix=/opt/kamailio Makefile:248: config.mak: No such file or directory normal Makefile.defs exec target architecture <i386>, host architecture <x86_64> ---- I did a process listing and noticed the following process waiting: 1719 make prefix=/opt/kamailio 1763 /bin/sh -c if [ -z "/usr/sfw/bin/gas" ] ; then echo "as" ; else if /usr/sfw/bin 1764 /usr/sfw/bin/gas -V I ended up making a wrapper script that just output the version information for "/usr/sfw/bin/gas -V" which let me get a little further. The wrapper script looks as follows: ---- #/bin/ksh if [ "$1" = "-V" ]; then echo "GNU assembler version 2.15 (i386-pc-solaris2.10) using BFD version 2.15" exit else /usr/sfw/bin/gas.bin $@ fi ---- However, when I now try a "make prefix=/opt/kamailio" I am faced with the following error: ---- gcc: installation problem, cannot exec `/usr/sfw/bin/gas': Exec format error ---- The complete output of the make is as follows: ---- make prefix=/opt/kamailio Makefile:248: config.mak: No such file or directory normal Makefile.defs exec target architecture <i386>, host architecture <x86_64> making config... yacc -d -b cfg cfg.y conflicts: 5 shift/reduce flex cfg.lex Makefile.defs defs skipped /usr/sfw/bin/gcc -g -O9 -funroll-loops -Wcast-align -m32 -minline-all-stringops -falign-loops -mtune=athlon -Wall -DNAME='"kamailio"' -DVERSION='"3.0.0-rc2"' -DARCH='"i386"' -DOS='solaris_' -DOS_QUOTED='"solaris"' -DCOMPILER='"/usr/sfw/bin/gcc 3.4.3"' -D__CPU_i386 -D__OS_solaris -DSER_VER=3000000 -DCFG_DIR='"/opt/kamailio/etc/kamailio/"' -DPKG_MALLOC -DSHM_MEM -DSHM_MMAP -DDNS_IP_HACK -DUSE_IPV6 -DUSE_MCAST -DUSE_TCP -DDISABLE_NAGLE -DHAVE_RESOLV_RES -DUSE_DNS_CACHE -DUSE_DNS_FAILOVER -DUSE_DST_BLACKLIST -DUSE_NAPTR -DDBG_QM_MALLOC -DUSE_TLS -DTLS_HOOKS -DSTATISTICS -DFAST_LOCK -DADAPTIVE_WAIT -DADAPTIVE_WAIT_LOOPS=1024 -DCC_GCC_LIKE_ASM -DHAVE_GETIPNODEBYNAME -DHAVE_SYS_SOCKIO_H -DHAVE_SCHED_YIELD -DHAVE_ALLOCA_H -DUSE_SIGACTION -DHAVE_DEVPOLL -DHAVE_SELECT -DHAVE_FILIO_H -c action.c -o action.o gcc: installation problem, cannot exec `/usr/sfw/bin/gas': Exec format error make: *** [action.o] Error 1 ---- If I remove the wrapper script then the make just hangs on the command "/usr/sfw/bin/gas -V". Would anyone know how I could work around the issue? Just an FYI, I am able to build Kamailio 1.5.2-notls on the same machine without any errors/hangs, although we are considering moving to Kamailio 3/Sip-Router when it is officially released, this is why I am trying to build v3.0.0 RC2 at the moment. If you need any further information please dont hesitate to ask, any help in resolving the issue would be greatly appreciated. Thanks Bruce

Hi, I simply trying to modify URI and FROM headers as follow. tcpdump packet capture shows the values are changed for both URI and FROM headers. However, the syslog only shows the new value for URI and not for FROM header. How can I verify new value in FROM header in the log file? # main request routing logic route { $rU = avp(i:1); $rd = avp(i:2); .... uac_replace_from("$avp(i:3)"); xlog ("fu after perl: $fu"); xlog ("ru after perl: $ru"); ... } Thanks, Rob

[Kamailio-Users] Using Sip Message in a third application.
by Olivier Détour 03 Dec '09

03 Dec '09

Hello, I'm using Kamailio 1.5.3. I configured it in a proxy mode. I would like to know what is the best way to forward the SIP message to a C application via a socket, block kamailio.cfg script, and reforward it to kamailio to continue his treatment. I found a ugly bay using PV as lock with a while loop, but this solution is not acceptable for me. I saw SEAS module, but it is only for Java Application server. Do you know a simple way to do it with an existing module ? Do I have to write my own module ? Thanks for your response, Regards, -- Olivier Détour EPITA 2009

Hi! IIRC correctly. topoh modules rewrites existing Via headers. Would it be possible to remove existing headers completely so that the forwarded request has only one Via header? regards klaus

[Kamailio-Users] ERROR:tm:add_uac: maximum number of branches exceeded
by alex pappas 02 Dec '09

02 Dec '09

Hello there, I'm using dispatcher to serial fork a call through many gateways. For a call to number 2XXXXXXXXX , first a try to connect through gateways A,B,C after that D,F , after that E,R , after that M,N and finally after those K,L. When the call is trying gateway N then I'm getting the ERROR:tm:add_uac: maximum number of branches exceeded. I found on internet that I'm exceeding the MAX_BRANCHES: branch=t->nr_of_outgoings; if (branch==MAX_BRANCHES) { LOG(L_ERR, "ERROR:tm:add_uac: maximum number of branches exceeded\n"); ret=E_CFG; goto error; } >From a trace I got , I see that kamailio is sending to each destination IP 8 INVITES and if there is no answer to that is continuing with next destination gateway sending also there 8 INVITES. When the number of INVITES is 52 then I get this error. Does anyone can suggest a way to change the MAX_BRANCHES MAX number ? Is is important to keep open the INVITEs from the first gateways because is an LCR scenario and if I get an answer from these gateways is important to complete through them. Any help is apreciated Thanks Alexandros

[Kamailio-Users] Random looped back audio issues with RTPPROXY
by tony＠everestbn.com 02 Dec '09

02 Dec '09

Hello, I'm having random audio issues (<10% of the time) with blind call transfers on a Polycom phone. According to RTPPROXY's logs, it seems it is substituting the same IP and port for the caller's and callee's address causing one end to hear their own voice while the other end hears nothing. INFO:rxmit_packets: caller's address filled in: a.b.c.199:17856 (RTP) INFO:rxmit_packets: guessing RTCP port for caller to be 17857 INFO:rxmit_packets: callee's address filled in: a.b.c.199:17856 (RTP) INFO:rxmit_packets: guessing RTCP port for callee to be 17857 The SDP in the SIP messages has all the correct IPs and ports and it appears from a SIP overview everything should work fine. Here is some background information: I am using Kamailio 1.5.3 with RTPPROXY 1.2.1. SIP PATH is as follows: PSTN Gateway---Kamailio--SIP Proxy Server--Polycom Phone RTP PATH: PSTN Gateway---Kamailio----Polycom Phone *There are nor firewalls or filters. Call Flow: I place a call from the gateway to the ip phone. Call is answered. When I do a blind transfer from the Polycom, the SIP Proxy sends an invite with no SDP, the gateway responds with a 200 with SDP and the SIP Proxy then sends an ACK with SDP. As I mentioned, this works most of the time and the SIP messages look identical for when the transfer works and when it doesn't. When it doesn't work the gateway end hears their own voice while the recipient Polycom transfer (usually another phone on the same proxy) hears nothing. Here is a portion of my configuration file: ..... if (is_method("INVITE")) { if((search("^Content-Type:[ ]*application/sdp")) || (search("^Content-Type:application/sdp"))){ rtpproxy_offer("fcr"); setflag(12); } } if (is_method("ACK")) { if((search("^Content-Type:[ ]*application/sdp")) || (search("^Content-Type:application/sdp"))) { rtpproxy_answer("fcr"); } } t_on_reply("1"); .... } onreply_route[1] { if (status=~"(180)|(183)|(2[0-9][0-9])"){ if((search("^Content-Type:[ ]*application/sdp")) || (search("^Content-Type:application/sdp"))) { if (isflagset(12)) { rtpproxy_answer("fcr"); } else { rtpproxy_offer("fcrl"); } } } } Any help would be greatly appreciated! Thanks, Tony

[Kamailio-Users] Kamailio -> Asterisk Redirect/Reinvite and Remote-Party-ID
by Florian Meister 02 Dec '09

02 Dec '09

Hi, basically I'm using this structure at the moment: SIP Users <----> Kamailio <-----> Asterisk <-----> PSTN I have to add a diversion-functionality at kamailio-level, so to simply rewrite $ru with something else defined in the database. That's working without problems. For billing issues, I also have to add a Remote-Party-ID header, set to the SIP user, which initiated the redirect in the database. Now to the problem: When a call is coming from PSTN, it's passing the asterisk server, then at kamailio level $ru is rewritten and sent back to asterisk (I'm talking about a redirect to a number in PSTN here) What I've seen from the logs is, that asterisk is seeing that it gets an invite back with the same call-id, and therefore it cancels the original invite and handles the whole call internally via the Local Channel. The Problem is, that in the invite sent from kamailio back to asterisk, I've set a Remote-Party-ID header to tell asterisk to set the Callerid correctly for billing purposes. Now it seems that asterisk is _ignoring_ this header from the second invite. So is this an expected behavior ? If yes, how to do it correctly ? Below you can see the verbose output of asterisk.

[Kamailio-Users] 487
by Anders 30 Nov '09

30 Nov '09

Hi, This question may belong in a general SIP forum - but I'll drop it here anyway, - hope I stir no big anger ;-) I'm running Kamailio 1.5, - use it for wholesale, and my customers typically send me calls from their Asterisk platform. I'm experiencing a very share of calls ending up in 487. This should be the client terminating the call - but is it my client (the provider with the Asterisk platform) or is it the final client - my client's client? Could Asterisk send a 487 for some reason? I've researched this (maybe not good enough!), but cannot find the answer: Does a 487 always mean that the client gave up and hung up? If this is the case, could high PDD be my problem - it's taking too long and the client gives up? Thanks!

[Kamailio-Users] Binding to multiple IP addresses on the same interface.
by Geoffrey Mina 30 Nov '09

30 Nov '09

Hello, I have a Kamailio machine that has multiple IPs assigned to a single interface. eth0 = 1.2.3.4 eth0:1 = 1.2.3.5 In my Kamailio config i have listen=eth0:5060 And it doesn't appear to be binding to my second IP address. What is the proper way to tell the server to bind to all IPs on a single interface? I don't want to specify the IP directly for binding as I use the same config across 4 Kamailio servers. listen=eth0:1:5060 (i think that's not correct) Thanks, Geoff p.s. I would do some testing, but this is a live machine and I don't want to bring it up and down.

[Kamailio-Users] Can kamailio bypass rtp media to backend sip server?
by Lei Tang 30 Nov '09

30 Nov '09

Hi everyone, I'm new to kamailio. I plan to setup a sip server cluster, Does someone can give me some suggestions if I can use kamailio as front server, which handle sip message and bypass rtp media message to backendserver, this mean the kamailio handle only sip message, the rtp packets are sent directed to backend server. The sip sequences is 1.softswitch send invite to kamailio 2.kamailio send invite to backend server. 3.backend server return 200 ok to kamailio 4.kamailio return 200 ok to softswitch, the ip and port in sip is from the backend server's msg, this make the softswitch send rtp direct to backend server. 5.rtp packets are transfered between softswitch and backend server. .... 6.backend server send bye to kamailio 7.kamailio send bye to softswitch. -- Lei.Tang lei.tlfly(a)gmail.com

[Kamailio-Users] Adding Columns to Database
by JR Richardson 29 Nov '09

29 Nov '09

Hi All, Using openser 1.1.0-notls (i386/linux) from debian etch package. Working with mysql database integration, working fine, using permissions module with 'trusted' table and alias_db module with the 'dbalias' table. I created the database and tables with openser_mysql cmd and things seemed to work out of the box. I ran into trouble when I dropped the database and manually created just the 'trusted' and 'dbalias' tables and added a few more columns in the tables [accountcode,notes,id(auto increment)]. When I restarted openser, no go, was getting table version and structure errors. So my question: is the table structure strict as per the openser_mysql script and are all 19 tables required for a properly running instance? I have not tried yet, but would it break if I added the new columns to the openser_mysql script created tables? Thanks. JR -- JR Richardson Engineering for the Masses

The configuration is "the same" (regarding handle_publish, handle_subscribe, pua_set_publish) as I've used in the kamailio-1.5.3 version. But - no NOTIFY messages with XML bodies are sent to the subscribers / watchers. Instead of using the setflag(X) method I´ve tried using the method "dlg_setflag(X)" for prohibiting crashes - that was accepted by kamailio. Were these modules tested (in combination with the dialog module) in the new version 3.0 RC1? - presence - presence_xml - presence_dialoginfo - pua - pua_dialoginfo - pua_usrloc It does not work in the SER variant of sip-router, too. Yesterday I've downloaded the current version with GIT, compiled the code, adapted the configuration. But the result is the same as with kamailio-3 RC1 (crash and no XML). For being sure that I have not made any mistake in the configuration, I've tested the functionality in the version 1.5.3 of Kamailio today. It works fine - the subscribers receive NOTIFY messages with XML body after every PRESENCE and DIALOG state change. Can anybody give me a hint?

Looking for documentation with SER 2.0
by inge 27 Nov '09

27 Nov '09

Hello here, I'm testing SER 2.0 on a dev plateform. I see that there's a lot of modifications beside SER 0.9.9. But I have a lot of pain to find documentation like SER Getting Started for 0.9.x to be able to understand the new routing method (ie. ser.cfg) and the databases scheme and all other parameters at the top of the config file. I install SERWeb too, the version 2.1, and it looks like very different too (don't know how to create an admin user, separate greeting/sip password, etc.). What's your recommandation about SERWeb version with SER2.0 ? Regards, Adrien .L

[Kamailio-Users] Inbound NAT detection and fix_nated_register() very poorly documented
by Alex Balashov 27 Nov '09

27 Nov '09

Greetings, I was faced with the following problem in Kamailio 1.5.2: I was using nathelper + rtpproxy + registrar and needed to relay media for calls going inbound to a NAT'd registrant through rtpproxy - only if the registrant is NAT'd. Here is the scenario: Media gateway Kamailio (on public IP) ----> registrar -----> NAT'd registrant (w/nathelper) I was handling registrations from NAT'd endpoints like this: if(nat_uac_test("1")) { force_rport(); fix_nated_contact(); } I was aware of fix_nated_register() but was not clear on its relationship to the 'received_param' parameter stored in 'location' and set as a modparam to both the 'registrar' and 'nathelper' modules, so I was not using it. Very quickly I ran into an obvious problem: if the contact stored in the 'contact' column in 'location' is already fixed up with the received IP:port, there is no way to know that the endpoint to which the call is going is behind NAT -- when lookup() is called, the RURI is set to the public IP:port. There are no flags of any kind that one can set during save() that persist while the contact binding is present for that AOR and can be resurrected on lookup(). Anyway, I eventually figured out how to fix this problem by empirical means, with no clear help from the nathelper documentation. It turns out that if I set the 'received_param' as a modparam to 'nathelper' and 'registrar' and handle registrations from NAT'd endpoints with fix_nated_register() instead, it will magically work. I made the following discoveries to arrive at this conclusion, both of which are not documented. This is why it will work: 1) When the original (RFC1918) 'contact' is stored in the 'location' table (if using DB, which I am), the 'received' parameter is stored alongside it and contains the public IP:port. When lookup() is called, the RURI domain is set to private address, e.g. if(!lookup("location")) { # Error handling here exit; } xlog("L_INFO", "[R-2:$ci] -> Registration resolved to RURI: $ru\n"): $ru here will contain something like this: sip:s@10.1.0.2:5060, the original and unmodified contact supplied by the UAC. But somehow, magically, when t_relay() is called the request will be relayed to a different RURI - one with the 'received' IP:port substituted in the domain portion. So, the request goes end up going to the correct place. This is, of course, because of the way the 'received' parameter is supposed to work when appended to a Contact URI. But the point is that it is not documented; nowhere in the documentation for lookup() or t_relay() does it say that this will transpire, and I have no way of knowing it except by observation. 2) For some reason, nat_uac_test("1") returns a positive result after the lookup() and confirms that the destination is NAT'd. This allows me to set a flag and then mangle the SDP in the reply to use rtpproxy for NAT traversal of media as well, e.g. route[2] { ... if(!lookup("location")) { # Error handling here exit; } if(nat_uac_test("1")) setflag(9); ... t_on_reply("1"); if(!t_relay()) sl_reply_error(); ... } ... onreply_route[1] { if(t_check_status("(180|183|200)")) { if(nat_uac_test("5")) fix_nated_contact(); if(search("Content-Type: application/sdp")) { if(isflagset(9)) { set_rtp_proxy_set("1"); force_rtp_proxy(); } } } } But if you examine carefully the documentation for nat_uac_test(), it says the following for bit flag 1: * 1- Contact header field is searched for occurrence of RFC1918 addresses. To me this means that nat_uac_test() should not work after the lookup() above. The only Contact header value that is present in the inbound INVITE handler is the Contact URI of the media gateway, which is a public IP address! Yet for some reason it works, as if by magic; apparently it is somehow implicit that a hidden "received" attribute of the RURI is also part of this check. This is also not documented, and is completely counterintuitive. Is there any possibility of clearing up documentation as to this point? Perhaps I have done something wrong here unknowingly; I have no idea. I know that my solution works but I cannot justify why in terms of the documentation. Is it very much to ask that the documentation be explicit about hidden but critically important mysteries like this?

[Kamailio-Users] Presence
by Andrey Utkin 27 Nov '09

27 Nov '09

Hello, all. My objective is to make a kamailio installation where phones call to each other by number and are able to monitor others using SUBSCRIBE. I use Kamailio 3.0.0 rc1 pulled from git. My config file is http://pastebin.ca/1675069 I had bad results with establishing calls, possibly because i frequently restarted kamailio, only once i had INVITE passing from one phone to other. RTPProxy mustn't work on a box with grey IP, i know. But my greatest convern now is notifications. I just want to say that i never got NOTIFYs with xml containing bodies, what was usual in Asterisk. First of all NOTIFYs that go immediately after SUBSCRIBEs also have no xml body. Please direct me what is wrong in my configuration regarding presence setup. Tell me what system info to provide.

Dear all, I'm having difficulties in the dialplan module. My problem is in the regular expressions added to the database. I tried some examples from previous users but they don't work for me. example: dpid 10 pr 100 match_op 0 match_exp ^123(.*)$ match_len 0 subst_exp ^123 repl_exp 0030 Previous example from Daniel that I found in user lists: s/subst_exp/repl_exp/ subst_exp - is regular expression that can be used to group parts of the input repl_exp - is used to build the output Example: you want to remove the first 0 and prefix +44 to a number: subst_exp=^0(.+)$ repl_exp=+44\1 Can someone provide an example that works with the latest kamailio please? Also where I can find more docs about dialplan? Thank you all Alex

[Kamailio-Users] tm retransmits and times out even though reponse is received
by Alex Hermann 26 Nov '09

26 Nov '09

Hello, I'm seeing an increasing amount of spurious timeouts on my proxies. Even though the proxy receives a "100 Trying" response immediately after relaying the request, tm will send retransmits and times out eventually. Below is a commented log snippet. The timeout occurs on the proxy named 'balancer1'. Both are on the same host. I verified that the 100 Trying response is received in a t_on_reply block, so it is recognized by tm as belonging to a transaction. When needed, I'll provide a debug log when it occurs again. Meanwhile, any idea what is causing this? This is on kamailio 1.5+svn5768 fr_timer = 10 fr_timer_avp = 2 # Initial request received on balancer May 15 12:32:01 balancer1[24170]: [2 INVITE] - New request. <sip:uac@domain> => <sip:uas@domain> May 15 12:32:01 balancer1[24170]: [2 INVITE] Relaying # Initial request received on proxy May 15 12:32:01 proxy1[23803]: [2 INVITE] - New request. <sip:uac@domain> => <sip:uas@domain> # Balancer receives 100 response May 15 12:32:01 balancer1[24166]: [2 INVITE] - Reply. 100 Trying # Proxy relays request May 15 12:32:01 proxy1[23803]: [2 INVITE] Relaying # Proxy receives retransmission from balancer ???

[Kamailio-Users] DSYSLOG_ASYNC option in Makefile.defs
by Torben Friese 26 Nov '09

26 Nov '09

Hi all, I have a problem with the Kamailio 1.5, if the DSYSLOG_ASYNC option is set I receive no log messages on a lenny-64bit system(fresh installed). Rsyslog is the standard log daemon in lenny. If I start directly from the command line with -dd I receive log messages. Any hints or ideas what is going wrong here ? The same option on a etch system works fine. best regards and thanking you in anticipation Torben

[Kamailio-Users] Commercial 24x7x365 Support
by Martin Werne 26 Nov '09

26 Nov '09

Hi! I have a customer (service-provider) that want to implement redundant openSER type of solution. On two locations (Europe and USA). They need access to high level support 24 hours a day, 365 days a year (by phone and remote-assistance via VPN). Do you know of any companies that delivers this kind of service? Anyone that has a list of companies that delivers solutions based on openSER? As I'm only one man, I'm not able to do this by myself...... ;-) Best regards, Martin

Hi to all, i implemented the P-Asserted-Identity and P-Preferred-Identity Header management. On the development server all is working properly but when i activate the new config on our production system i start to get crashes of the openser process: openser[31483]: segfault at 0000000000000000 rip 0000000000487853 rsp 00007fff94c9f1a0 error 4 openser[6511]: segfault at 0000000000000025 rip 00000000004214ce rsp 00007fff80f05480 error 4 openser[8967] general protection rip:4214ce rsp:7fff05fbb530 error:0 openser[9872] general protection rip:4214ce rsp:7fffd2b630d0 error:0 I checked the core dump with gdb and i have this info from the core: Core was generated by `/usr/sbin/openser'.

The first or the second one? The first should work, at least the from header should be rewritten by the function. The second authentication will not work this way (if it requires a different from header) because the proxy "remembers" for the header changes done before the first t_relay() function call and applies the same header modifications also for any other branch added from failure route. Hence, the outgoing SIP request to the second provider will contain the same from HF as the request to the first provider. The easiest way is to apply the header modifications in branch route if you do not need to reuse them later from failure route. Modifications done in branch routes are valid only within that branch. > > I moved uac_replace_from to my failure route to call once again before > uac_auth, but got config error as i can't use uac_replace_from in > failure_route. I think you already use this function from failure route because it is in a route block that is included from failure route. The only difference is that the syntax checker does not recognize the issue. I am not familiar with uac_replace_from() but after having a quick look at the function I think it is safe to use it from here. > Ok i will use textops to rewrite, but it is ugly? The main difference is that uac_replace_from() restores the original From HF when the response if forwarded. If you use textops module then you need to restore the header manually. > no. Maybe i should > call uac_replace_from in branch route? I would suggest this way. Both for the first and for the second provider. Miklos > > Thanks

[Kamailio-Users] ERROR:mi_fifo:mi_fifo_server: fifo command must begin with :: early_dialogs (1.5 rev 5834)
by Iñaki Baz Castillo 21 Nov '09

21 Nov '09

Hi, I use the Munin plugin I did in various servers running Kamailio 1.5 (Debian 64 bits). The munin plugins performs the Mi command: kamctl fifo get_statistics inuse_transactions In one of them the installed revision is 5834 and the plugin works perfectly, no errors in 3 months with high traffic. However in the other server (revision 5925) there are no traffic yet but the plugin fails sometimes (maybe once each 2-3 days). Sometimes it gets an error: ERROR:mi_fifo:mi_fifo_server: fifo command must begin with :: early_dialogs and sometimes it gets wrong value: kamctl fifo get_statistics inuse_transactions => 2819624 (with no traffic !!!) In the second case the Munin grapsh gets corrupted due to so high value. Could it be a bug in dialog module?

Hi, it is me again.

[Kamailio-Users] Dialog timed calls
by Jason Penton 19 Nov '09

19 Nov '09

Hi All, Has anyone else noticed the significant inaccuracy of the timeout in the dialog module? We are using: modparam("dialog", "timeout_avp", "$avp(i:10)") However, the actual call is torn down a NUMBER of seconds past the timeout supplied. In some instances, for long calls, it is out by 30seconds or more....? For shorter calls it is accurate with a second or so. Anyone have any input, ideas? Cheers Jason

[Kamailio-Users] How to configure alias_db_lookup in config script
by JR Richardson 18 Nov '09

18 Nov '09

Hi All, I have a real simple load balancer proxy setup using the dispatcher module, works great. I want to do an alias lookup before I send the calls through to the dispatcher, but I can't seem to find a good example of how that should be setup in the config script. I've tried different things, the aliase_db_lookup is working but if a user is not in the database, the call loops and does not continue on to the dispatcher. Here is my current route script (this does not work): route{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; alias_db_lookup("dbaliases"); t_on_failure("1"); t_relay(); ds_select_dst("1", "4"); t_on_failure("1"); t_relay(); } failure_route[1] { ds_next_dst(); forward(); } I think there should be an 'if' 'then' or 'if' 'else' separating the alias_db_lookup and the ds_select functions, but I'm not sure of the syntax and where the curly brackets need to be. Thanks. JR -- JR Richardson Engineering for the Masses

Dear all, I'm trying to play Early Media instead of Ringing WHEN an 180 Ringing OR 182 Call Queue message is received from the destination UAC. In the onreply_route[1] I added the following lines in bold: I use kamailio 1.5 and I have NAT enabled. onreply_route[1] { xdbg("incoming reply\n"); if ((isflagset(5) || isbflagset(6)) && status=~"*(180)|*(183)|(2[0-9][0-9])") { force_rtp_proxy(); } * if (status=~"(180)") { rtpproxy_stream2uac("/usr/local/etc/rtpproxy/ast-ivr.alaw",""); } else { rtpproxy_stop_stream2uac(); }* if (isbflagset(6)) { fix_nated_contact(); } } When I get from a UAC an 180 Ringing does not play the media and also in the syslog I see the following ERRORs: Nov 17 14:11:29 YGOR /usr/local/sbin/kamailio[4681]: ERROR:nathelper:extract_body: message body has length zero Nov 17 14:11:29 YGOR /usr/local/sbin/kamailio[4681]: ERROR:nathelper:force_rtp_proxy: can't extract body from the message Nov 17 14:11:29 YGOR /usr/local/sbin/kamailio[4681]: ERROR:nathelper:select_rtpp_node: script error -no valid set selected Nov 17 14:11:29 YGOR /usr/local/sbin/kamailio[4681]: ERROR:nathelper:rtpproxy_stream: no available proxies Thanks in advance for any help Alex

[Kamailio-Users] Dialplan Module Confusion
by JR Richardson 18 Nov '09

18 Nov '09

Hi All, I'm new to the list and fairly new to the vastness which is kamailio and the tons of modules and options. I'm trying to figure out the simplest method to accomplish the following scenario: SIP call comes in, match DID in database (MySQL), rewrite ruri with associated database entry matching DID, relay call to specified gateway, if no matching entry for DID is in database, forward call to dispatcher module and continue processing call (I already use the dispatcher module for load balancing, just need to implement DID call routing before I send calls to dispatcher) I've been reading about the following modules, dialplan, LCR, drouting, alias_db. I think dialplan is what I really need, but I'm confused about what entries to put in the database to match on 10 digit DID: match-op = 0 (equal) match_exp= 1112223333 match_len= 10 subst_exp= ?? is this where I would put the ruri sip:1112223333@10.10.10.10<sip%3A1112223333(a)10.10.10.10>(I'm not sure of the syntax here) repl_exp= ?? not sure what this is for can more than one database entry have the same id? and also I could use a practical example of how this would work int he config file: dp_translate("240", "$ruri.user/$ruri.user"); t_relay?? Any guidance on this would be much appreciated. Thanks. JR -- JR Richardson Engineering for the Masses

[Kamailio-Users] dbtext, domain and caching
by Andreas Granig 17 Nov '09

17 Nov '09

Hi, I was trying to use caching in domain module with the dbtext backend, but on startup I get the error ERROR:domain:reload_domain_table: Database problem Looks like something is wrong with the column type when it's checked in line if ((ROW_N(row) == 1) && (VAL_TYPE(val) == DB_STRING)) { ... } The db file for domain module looks like: id(int) domain(str) last_modified(int) 1:test.local:0 Any hints on that? Probably a problem with dbtext module, since it works with mysql? Best regards, Andreas

[Kamailio-Users] Test a string concatenated with an AVP

Hi all, actually I test if the R-URI contains the value *44* with: if (uri=~"^sip:\*44\*[0-9]+@") { ... } Now I want to read the value 44 or *44* from an AVP. Tried using directly the avp or assigning it to a variable, without success. ex.: $var(x) = "sip:" + $avp(s:code) + "[0-9]+@"; How can I solve this problem? Thank you very much. Regards. -- Antonio

[Kamailio-Users] Question about force_send_socket() as it relates to record_route()
by Geoffrey Mina 16 Nov '09

16 Nov '09

Hello, I have a scenario where I need to send traffic to my carrier from two different source IP addresses. The carrier charges me one rate for dialer based traffic and another rate for standard outbound origination. I am planning on using the force_send_socket() method to manually set the source IP address. My question is how does this correlate to my usage of the record_route() function? Do I need to force_send_socket() BEFORE inserting the Record-Route header? Are there any other things I need to be concerned with while using the TM module? Thanks!

[Kamailio-Users] Possible setups question
by Varga Levente 16 Nov '09

16 Nov '09

Hello! I'm new to Kamailio so I want to ask a few questions before to be sure that I'm not trying to do something that cannot be done using Kamailio. The question would be if it is possible to do the following things using Kamailio: I want to setup the following configuration, two or more Asterisk servers with one redundant server in standby using Kamailio to route and partition the number. of users in a fixed manner. What I mean by that for instance if I have 200 users I want that the first 100 user to register and use server number one and the other 100 user to use the server number two. A user cannot migrate from one server to another they have to be always on the designated server from start. Kamailio would act as a unified front-end/gateway for the client (they will use the same entry point not being aware that there a number of Asterisk server beside it). Also there is a need for a N+1 redudancy scheme, that is if one of the servers fail or get very busy the new calls and registration should be redirected to the standby server on the fly (user account data replication would be taken care of on the spot). Can all this be done using Kamailio as a gateway and SIP router? Thank you! levi -- Lege, lege, relege, ora, labora et invenies.

Hello, Our VoIP provider doesn't provide CNAM to us so we have to access an outside provider for this. Can anyone point me in the right direction for running an http request and passing the result back out so the pbx can pick grab the callerid. I know that OpenSER they has the Utils module but SER doesn't have that. Any ideas?

[Kamailio-Users] Remote management and security
by Brian 13 Nov '09

13 Nov '09

Hi, Does anyone know how I can do remote management of Kamailio in a secure way? Looking at the documentation for MI_DATAGRAM and MI_XMLRPC, there does not seem to be a way to authenticate the request, or a way to restrict requests to specific IP ranges. I want to be able to send management commands remotely, but I don't to make this wide open. Thanks, Brian.
