how to get a value from SIP INVITE Header
by sai sudheer 14 Oct '20

14 Oct '20

Hii Please help me to get the a value from SIP INVITE header reached to kamailio like INVITE sip:+341930203454@sub.domain.com;myid=+34@sub.domain.com SIP/2.0 and i want to save the myid value +34 into a variable, without the domain name. $var(uri) = $sel(ruri); xavp_params_explode("$(var(uri){s.unbracket})", "uri"); xlog("L_INFO", "$var(uri) Received converted to $xavp(uri=>myid[0])\n"); I tried above and it prints +34(a)sub.domain.com But i want to just save +34 into a variable to further check the prefix based routing from the database. 1) Could you please help how to get it or If there is any alternate/single line approach to get this value? 2) $var & $xavp are process-local variables, and they cant be shared with other calls? Right 3) What is the best module to route calls based their prefix ? pstn_route or dynamic routing or any suggestions? Please help, thanks in advance.

Hello, I see parsing errors on 302 contact header that seems compliant to RFC : Contact:<sip:172.16.0.21:5060>;q=0.5,<sip:172.16.0.22:5060>;q=0.25 <core> [core/parser/parse_addr_spec.c:479]: parse_to_param(): invalid character ',' in status 27: [;q=0.5] Is there an error in my contact or is it truly a parsing error ?

routing calls based on prefix
by Andy Kama 13 Oct '20

13 Oct '20

Hi All, What is the best way to approach this? example if a call comes into kamailio with a specific number it example to:123456789 it must go to the dispatcher module but if a call comes with any other number it must route to a uac or can you use uac with dispatcher? basically i want to route inbound calls to a dispatcher and calls from that dispatcher out a uac

Caseless regex

Hello, Is it possible write more readable regular expression if ($tU =~ "(?i)^test$") { ... } instead of "^[tT][eE][sS][tT]$"? On the first option, I get the error: 0(47250) ERROR: <core> [core/rvalue.c:3038]: fix_match_rve(): Bad regular expression Regards, Marat

Re: [SR-Users] Local cache registration
by David VILLAUME 13 Oct '20

I read again the uac doc and didn’t find a way to perform this using the functions that seems to require credentials that I don’t have on the kamailio host. Is the uac module really designed to perform this operation is that way ?

You can handle upstream registrations in different intervals than the ones you receive.

Dispatcher stops working
by Sergio Charrua 12 Oct '20

12 Oct '20

Hello, Using Kamailio 5.1.6 for load balancing & failover, I noticed that from time to time, and very rarely, the dispatcher module stops dispatching to the Asterisk servers. I have to execute a "kamcmd dispatcher reload" for it to (re)start working. This is my dispatcher.list : 1 sip:10.19.XXX.YYY:5060 0 1 duid=sipgw01;maxload=100 1 sip:10.19.XXX.YYY:5060 0 2 duid=sipgw02;maxload=100 1 sip:10.19.XXX.YYY:5060 0 3 duid=sipgw03;maxload=100 1 sip:10.19.XXX.YYY:5060 0 4 duid=sipgw04;maxload=100 This is my dispatch routes: # Dispatch requests route[DISPATCH] { if(!ds_select_dst("1", "10","4")) { xlog("L_INFO","no destination selected from dispatcher list!"); send_reply("404", "No destination"); exit; } xlog("L_INFO","going to <$ru> via <$du>\n"); t_on_failure("RTF_DISPATCH"); route(RELAY); exit; } # Sample failure route failure_route[RTF_DISPATCH] { if (t_is_canceled()) { exit; } xlog("L_INFO", "Media server $du failed to answer, selecting other one!"); # next DST - only for 500 or local timeout if ( t_check_status("500") || (t_branch_timeout() && !t_branch_replied()) ) { #mark the destination Inactive and Probing ds_mark_dst("ip"); if(ds_next_dst()) { t_on_failure("RTF_DISPATCH"); route(RELAY); exit; } } } I suspect that the ds_mark_dst("ip") command in RTF_DISPACTH is the cause. Is there any think I can improve on this? Or any know bug with the dispatcher in Kamailio 5.1.6 version? Thanks in advance, *Sérgio Charrua*

Logging problem
by Jan Rozhon 12 Oct '20

12 Oct '20

Hi, sorry for quite stupid and newbie questions, but I am out of ideas. 1. On one of my Debian 10 servers I am unable to stop logging kamailio messages to /var/log/syslog. It is funny, because I have 3 more servers where it works but on this one, it doesnt and no matter what I try it still keeps sending logs to syslog (and to the file configured). My related configs: /etc/kamailio/kamailio.cfg log_stderror=no log_facility=LOG_LOCAL7 /etc/rsyslog.conf local6.* /var/log/kamailio/cdr.log local7.* /var/log/kamailio/kamailio.log /etc/rsyslog.d/kamailio.conf if $programname contains 'kamailio' then /var/log/kamailio/kamailio.log & stop /etc/systemd/system/multi-user.target.wants/kamailio.service SyslogIdentifier=kamailio 2. It is probably related to 1. I am unable to get the CDRs logged to anything else but /var/log/syslog. I tried database (nothing) and setting cdr_facility and again nothing. It just keeps sending everything to /var/log/syslog. Related configs: modparam("acc", "cdr_enable", 1) modparam("acc", "cdrs_table", "acc_cdrs") modparam("acc", "cdr_facility", "LOG_LOCAL6") Example output in syslog file: Sep 30 09:21:41 sip2 /usr/sbin/kamailio[1151]: NOTICE: {2 21 INVITE ZPZI7Hqytw} acc [acc.c:279]: acc_log_request(): ACC: call missed: timestamp=1601450501;method=INVITE;from_tag=1GH5hGQxN;to_tag=QwcYFet;call_id=ZPZI7Hqytw;code=486;reason=Busy here;src_user=XXXXXXXXX; Is there something trivial I am missing? Thank you. Regards, Jan
