Music on hold with freeswitch as SBC
by Gautam Batra 22 Dec '11

22 Dec '11

Hello, I have a kamailio sip proxy server with freeswitch acting as SBC. I want to redirect the call to freeswitch when hold is pressed so that i can play music on hold. I tried this by using rewritehostport in case of a re-invite, but the call drops in that case. Could someone please help me with this? Gautam

Hi, sometime we get the following error after we restart the kamailio for a while: ERROR: <core> [timer.c:972]: ERROR: slow timer too slow: overflow (1048 - 25 = 1023) ... last message repeated 138times .... ERROR: <core> [timer.c:972]: ERROR: slow timer too slow: overflow (1048 - 25 = 1023) last message repeated 49 times it print them continuously.... is it normal? How I can fix it? Thank you very much!

anyone with opensuse around?
by Daniel-Constantin Mierla 22 Dec '11

22 Dec '11

Hello, is anyone here having an opensuse available for using to do some tests? It is about the radius modules, it seems opensuse does now have radiusclient-ng, but the client library from freeradius. They should be quite similar and we should be able to compile with freeradius client library, like make FREERADIUS=1 ... I tried on opensuse build service and it fails due to some conflict on DBG definition. It is hard to troubleshoot on OBS, so maybe someone can give a hand and find the fix faster -- I can provide guidelines or if I can get shell access (just simple user) would be better (write me directly in this case). The goal is to get the radius modules packaged as rpm on opensuse. Thanks, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com http://linkedin.com/in/miconda -- http://twitter.com/miconda

Re: [SR-Users] Who can tell me how to get the dialog-based CDRs ?

Calling loose_route() makes sure that for a given sequential request (which includes BYE messages) it is properly linked to its dialog. This is carried out by either adding cookies to Route headers or trying to match the dialog-identifying SIP headers (From-Tag, To-Tag, and Call-ID). This so-called "matching mode" is set to "DID only" which corresponds to using cookies in Route headers. For this to work, you must ensure that calls are being enriched with Record-Route headers. So one possible reason why things didn't work for you is that you used "DID only" matching mode (which you apparently did as you configuration didn't deviate from the default) but forgot to add Record-Route headers. Alternatively, you could set matching mode to 2 (SIP header-based matching only) or 1 (cookie-based but fallback to header-based) to get things going dialog-wise. See the dlg_match_mode modparam documentation here: http://sip-router.org/docbook/sip-router/branch/master/modules_k/dialog/dia… . > The main reason "insert" can not insert the data into cdr table is > loose_route() returns "0", which has no "Route:" header , and the > "insert" will never be executed.

Originally, I was considering the > dialog will be destroyed immediately when then "BYE" message received. > The results of my experiments prove that it isn't. But I am not sure > whether my conclusion is right. In the old days, dialogs would indeed be destroyed as soon as the transaction correlating to the first BYE request was deleted. This was changed a while in ago in order to be able to handle responses to such BYE requests too. So these days, dialogs do not get destroyed until a BYE-completing response is seen. (More specifically, until the transaction related to a BYE-completing response is terminated. Or, if that BYE request never sees a response and its transaction times out, whichever comes first. But that's just details.) You probably shouldn't be satisfied with updating database entries during route[RELAY] (at least not only). If it's not working on processing of a final BYE request, this indicates that dialog tracking isn't properly working for you (see my explanation above as to why). Whatever you store in dialog variables during an INVITE may not be valid by the time you persist to database. And regarding CDR generation using Kamailio's built-in mechanism: It's part of the acc (accounting) module (not dialog as I initially claimed). You may want to look at the documentation to see if it's a fit for you: http://sip-router.org/docbook/sip-router/branch/master/modules_k/acc/acc.ht… HTH, --Timo > ------------------ Original ------------------ > From: "Timo Reimann"<sr(a)foo-lounge.de>; > Date: Wed, Dec 21, 2011 06:51 PM > To: "SIP Router - Kamailio (OpenSER) and SIP Express Router (SER) - > Users Mailing List"<sr-users(a)lists.sip-router.org>; > Cc: "sunny_day"<416415455(a)qq.com>; > Subject: Re: [SR-Users] Who can tell me how to get the dialog-based > CDRs ? > > > Hey, > > > Am 21.12.2011 um 07:03 schrieb sunny_day: >> My object: get the dialog-based CDRs >> >> SIP proxy: kamailio-3.2.0 >> >> My script: >> >> loadmodule "dialog.so" >> ...... >> modparam("dialog","dlg_flag",4)#Must be set to create the dialog > associated to an initial request. >> modparam("dialog","db_url","mysql://xxx:xxx@localhost/albert") >> modparam("dialog","table_name","dialog") >> ....... >> request_route{ >> if( is_method("INVITE") && !has_totag()) >> { >> dlg_setflag(4); >> dlg_var(start_time)=$TS; >> dlg_var(caller)=$fU; >> dlg_var(caller)=$tU; >> } >> dlg_manage(); >> ...... >> # dispatch destinations to PSTN >> route(PSTN); >> # user location service >> route(LOCATION); >> route(RELAY); >> } >> ......... >> route[WITHINDLG] { >> if (has_totag()) { >> # sequential request withing a dialog should >> # take the path determined by record-routing >> if (loose_route()) { >> if (is_method("BYE")) { >> setflag(FLT_ACC); # do accounting ... >> setflag(FLT_ACCFAILED); # ... even if the > transaction fails >> >> sql_query("cd", "insert into > cdr(caller,callee,start_time,duration) > values($dlg_var(caller),$dlg_var(callee),$dlg_var(start_time),$DLG_lifetime)", > "rd"); >> sql_result_free("rd"); >> } >> if (is_method("ACK")) { >> route(NATMANAGE); # ACK is forwarded statelessy >> } >> route(RELAY); >> } >> ........ >> >> >> My issue is : >> >> The dialog records can be wrritten into the dialog table. > But , the sql_query can not executed.

carrierroute issue with rewrite host
by Uri Shacked 21 Dec '11

21 Dec '11

Hi, I am using kamailio (only one) as routing engine. I have 2 gateways. Both of them sending calls to kamailio. When i use the carrierroute module i need to change (and succeed) the user ($rU). But, i need to send the call (the invite) back to the gateway that sent me the call from the beginning (it can be either one of those 2). So, my problem is that i don’t want to rewrite the host in carrierroute, just the user. If i leave the rewrite_host field empty, it is considered to be "black list" and drops the call. If i rewrite the host, i can send the call to the second gateway that was not the one that sent the call, and the call drops as well. any ideas how to use carrierroute for changing user only and send the invite back to the gateway that originally sent the call? Thanks, Uri

Issue when SRTP enabled in the SIP clients
by Jonathan Martin 21 Dec '11

21 Dec '11

Hi, I followed this web article to install Kamailio 3.2 and RTPProxy on Debian Squeeze x64: http://kb.asipto.com/kamailio:skype-like-service-in-less-than-one-hour The system is running on a public IP address outside of our corporate LAN. I have been testing it using pjsua v2 alpha 2 from the pjsip.org project. I am having an issue when I enable srtp in the pjsua clients. If both pjsua clients are running on machines on our corporate LAN (symmetric NAT), the call succeeds and I get audio and video. If one of the clients is running outside of the corporate LAN, the call connects but I do not get any audio or video. If I turn off srtp in both clients and try the call again, audio and video starts working. Is there any additional configuration I need to make in the kamailio.cfg file when I intend to use srtp in the clients? RTPProxy info: Basic version: 20040107 Extension 20050322: Support for multiple RTP streams and MOH Extension 20060704: Support for extra parameter in the V command Extension 20071116: Support for RTP re-packetization Extension 20071218: Support for forking (copying) RTP stream Extension 20080403: Support for RTP statistics querying Extension 20081102: Support for setting codecs in the update/lookup command Extension 20081224: Support for session timeout notifications Kamailio info: version: kamailio 3.2.0 (x86_64/linux) flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled on 10:23:25 Nov 2 2011 with gcc 4.4.5 Regards, --Jonathan

回复： Why? there isn't a syslog.conf under mykamailiodirectory?
by sunny_day 21 Dec '11

21 Dec '11

Elena, your advice is very useful for me. Thank you very much. :-) However,i think i should introduce the environment I now used. First, there are 3 users on the linux, and one kamailio.cfg for each user. I am not the root user. So i don't have the priviledge to write the diretory---->/var/log/messages According the introduction you provided for me, I want to setup my own log file. But I am not sure whether it will work. The idea is: 1. In kamailio.cfg set "log_facility=LOG_LOCAL5" 2. In syslog.conf set # Log anything (except mail) of level info or higher. # Don't log private authentication messages! *.info;mail.none;authpriv.none;cron.none;local5.none /var/log/messages 3. In syslog.conf set # log messages with LOG_LOCAL5 in /var/log/kamailio.log local5.* -/home/albert/mylocal/myvar/log/kamailio.log Any idea will be appreciated.
