Hello, Anyone knows a tool/software (NOT CDRTool) to graphically visualize the SIP traces recorded in database by Kamailio's siptrace module? Thanks Reda

RFC 5626 Outbound/ sip.instance in Contact header?
by Daniel Pocock 15 Apr '12

15 Apr '12

Hi, I'm just wondering if there has been any type of work to implement any part of RFC 5626, particularly the registrar server code? Lumicall now generates a UUID at install time, and sends that as sip.instance in the Contact header. It always sends reg-id=1 (only trying one proxy at the moment). Although this is not a full implementation of the spec, it seems to be sufficient for eliminating extra Contact records in the repro registration server (from reSIProcate). However, I've noticed Kamailio doesn't seem to understand this parameter yet. Regards, Daniel

200 OK with SDP got wrong Contact HF after fix_nated_contact()

Hello! I got the following problem. My 200 OK with SDP sends the private ip of the B-Leg party.

LCR routing and From Uri
by Alexey Mechanoshin 13 Apr '12

13 Apr '12

Hello all. In my config added LCR routing by this manual: http://www.amitnepal.com/using-lcr-with-kamailio/ and if added, to 'lcr_rule' table, uri to 'from_uri' column - kamailio always reply 503 - 'No More Gateways' :-( If remove data - routing work. A'm using last kamailio from git ... Please help me change my config to working routing by checking 'from_uri' . Need check routing prefix 5499 only from IP 192.xxx.xxx.59 , as example.

rtpproxy 1.2.1 segfaults with kamailio 3.2.2 in bridging mode
by Karsten Horsmann 12 Apr '12

12 Apr '12

Hi all, i try to register at the rtpproxy mailinglist, but its still pending. Maybe someone here had the same issue. In my multihomed setup (with mhomed=1 in kamailio.cfg) i had segfaults from rtpproxy if i called rtpproxy_manage with params. Notice that i must run rtpproxy as root to get core files. Any hints? Maybe my kamailio config isnt right? ulimit -c unlimited ; /usr/local/bin/rtpproxy -u root -s /home/sys/bin/rtpproxy.sock -l <PUBLIC-IP> 172.20.100.74 -d DBUG:LOG_LOCAL5 Apr 10 15:13:40 kamailio1 rtpproxy[19728]: DBUG:handle_command: received command "V" Apr 10 15:13:40 kamailio1 rtpproxy[19728]: DBUG:doreply: sending reply "20040107#012" Apr 10 15:13:40 kamailio1 rtpproxy[19728]: DBUG:handle_command: received command "VF 20050322" Apr 10 15:13:40 kamailio1 rtpproxy[19728]: DBUG:doreply: sending reply "1#012" Apr 10 15:13:40 kamailio1 rtpproxy[19728]: DBUG:handle_command: received command "VF 20071116" Apr 10 15:13:40 kamailio1 rtpproxy[19728]: DBUG:doreply: sending reply "1#012" Apr 10 15:13:40 kamailio1 rtpproxy[19728]: DBUG:handle_command: received command "VF 20081102" Apr 10 15:13:40 kamailio1 rtpproxy[19728]: DBUG:doreply: sending reply "1#012" Apr 10 15:13:40 kamailio1 rtpproxy[19728]: DBUG:handle_command: received command "UEIc107,0,8,101 NTgxNzRkMmJmYzFlYjg2NTdiN2Q3MzJkYjkzMzI3Yjk. 217.XXX.XXX.XX 49814 00671612;1" Apr 10 15:13:40 kamailio1 rtpproxy[19728]: INFO:handle_command: new session NTgxNzRkMmJmYzFlYjg2NTdiN2Q3MzJkYjkzMzI3Yjk., tag 00671612;1 requested, type strong Apr 10 15:13:40 kamailio1 rtpproxy[19728]: INFO:handle_command: new session on a port 36156 created, tag 00671612;1 Apr 10 15:13:40 kamailio1 rtpproxy[19728]: INFO:handle_command: pre-filling caller's address with 217.XXX.XX.XX:49814 Apr 10 15:13:40 kamailio1 rtpproxy[19728]: DBUG:doreply: sending reply "36156 212.XX.XX.XXX#012" (gdb) bt #0 0x0804ccb8 in ishostseq (ia1=0x99c54c8, ia2=0x0) at rtpp_util.c:55 #1 0x080514ba in handle_command (cf=0xbffb9d8c, controlfd=5, dtime=1334063620.8220949) at rtpp_command.c:761 #2 0x0804afb7 in process_commands (argc=9, argv=0xbffda634) at main.c:752 #3 main (argc=9, argv=0xbffda634) at main.c:856 (gdb) p ia1->sa_family $1 = 2 (gdb) p ia2->sa_family Cannot access memory at address 0x0 # RTPProxy control route[NATMANAGE] { #!ifdef WITH_NAT xlog("NATMANAGE M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); if (is_request()) { if(has_totag()) { if(check_route_param("nat=yes")) { setbflag(FLB_NATB); } } } if (isbflagset(FLB_NATB)) return; if (dst_ip == PUBLIC_IP ) { xlog("rtpproxy_manage extern zu intern\n"); rtpproxy_manage("OCFEI","172.20.10.74"); } else { xlog("rtpproxy_manage intern zu extern\n"); rtpproxy_manage("OCFIE","PUBLIC_IP"); } if (is_request()) { if (!has_totag()) { add_rr_param(";nat=yes"); } } if (is_reply()) { if(isbflagset(FLB_NATB)) { fix_nated_contact(); } } #!endif return; } -- Mit freundlichen Grüßen *Karsten Horsmann*

Variable $fu Kamailio 3.2
by Gilbert T. Gutierrez, Jr. 11 Apr '12

11 Apr '12

I wrote the code below to rewrite an extension to a phone number (It is called in route[LOCATION]). This code works fine with MULTIDOMAIN enabled but when I run it as a single domain the line $fu=$var(b); does not seem to work.. You can see that I have several xlog lines outputting the variable values into my /var/log/messages. $var(b) has the correct value in it, so I do not know what is happening. I have also included the /var/log/messages output which I redacted the phone number, domain, and extension for security purposes. I am sure I am going about this backwards, but can someone provide me some guidance as to what is going wrong? Thank you, Gilbert # Rewrite - Gilbert route[REWRITE] { # This section rewrites the outbound calling number so that caller id works correctly. #!ifdef WITH_REWRITE # lookup an outbound number to replace the extension with $var(b)="NO REV"; sql_xquery("ca","select number from pioutalias where username='$fU'","ra"); # determine if a outbound number exists if ($xavp(ra=>number)) { $var(b)="sip:" + $xavp(ra=>number) + "@" + $fd; xlog("L_INFO","var(b): '$var(b)'"); xlog("L_INFO","fu: '$fu'"); # Assign the outbound calling number $fu=$var(b); xlog("L_INFO","New fu: '$fu'"); } sql_result_free("ra"); # see if it found a number and log if it did not if ($var(b)=="NO REV") xlog("L_INFO","No number found for extension: '$fu'"); #!endif } /var/log/messages output Apr 9 14:38:38 tempfax /usr/sbin/kamailio[6088]: INFO: <script>: var(b): 'sip:602XXXXXXX@xxxx.com' Apr 9 14:38:38 tempfax /usr/sbin/kamailio[6088]: INFO: <script>: fu: 'sip:30XXXXX@xxxx.com' Apr 9 14:38:38 tempfax /usr/sbin/kamailio[6088]: INFO: <script>: New fu: 'sip:30XXXXX@xxxx.com'
