Manipulate From URI username
by Gertjan Wolzak 04 Oct '17

04 Oct '17

Hello Kamailions, Im trying to manipulate the username from the from uri, but not having any luck, I must be doing something wrong. I receive a from uri username that is prefixed with 888, now I am trying to remove the triple 8. I have configured the following: line 1090 if($fU=~"^888"){ 1091 strip(3); 1092 } 1093 route(GETGROUP); But I do not get any result, the debug shows the following: 29(9610) exec: *** cfgtrace:request_route=[MOMANX] c=[/usr/local/etc/kamailio/kamailio.cfg] l=1093 a=16 n=if 29(9610) exec: *** cfgtrace:request_route=[MOMANX] c=[/usr/local/etc/kamailio/kamailio.cfg] l=1091 a=45 n=strip 29(9610) exec: *** cfgtrace:request_route=[MOMANX] c=[/usr/local/etc/kamailio/kamailio.cfg] l=1093 a=5 n=route Does anyone see what I am doing wrong? Help would be appreciated. Rgds, Gertjan Wolzak

Debian Stretch
by Jurijs Ivolga 03 Oct '17

03 Oct '17

Hi Guys, I recently tried to use Debian Stretch in production and it didn't went well. On load(500k-700k SIP messages per day) I get a problem that at some point there was a pike of CLOSE_WAIT connections(up to 2k of CLOSE_WAIT connections) and no new connections was possible, I tried to figure out where problem is, but I didn't found anything in system or Kamailio logs, Kamailio just stopped to receive traffic via TCP, but UDP continued to work. Test environment where was no load I didn't faced such issue. Just curious is there anybody who are using Debian Stretch in production without issues? Jurijs

Kamailio htable mod-init route: Main process exited before writing to pipe
by George Diamantopoulos 02 Oct '17

02 Oct '17

Hello all, I've been trying to utilise event_route[htable:mod-init] in order to load information from the database into an htable on startup. However, Kamailio exits with an error for no obvious (to me) reason. Here's the log output: DEBUG: htable [htable.c:226]: child_init(): rank is (-127) DEBUG: htable [htable.c:259]: child_init(): executing event_route[htable:mod-init] (2) DEBUG: <core> [core/parser/msg_parser.c:600]: parse_msg(): SIP Request: DEBUG: <core> [core/parser/msg_parser.c:602]: parse_msg(): method: <OPTIONS> DEBUG: <core> [core/parser/msg_parser.c:604]: parse_msg(): uri: < sip:you@kamailio.org> DEBUG: <core> [core/parser/msg_parser.c:606]: parse_msg(): version: <SIP/2.0> DEBUG: <core> [core/parser/parse_via.c:2639]: parse_via(): end of header reached, state=2 DEBUG: <core> [core/parser/msg_parser.c:491]: parse_headers(): Via found, flags=2 DEBUG: <core> [core/parser/msg_parser.c:493]: parse_headers(): this is the first via ERROR: <core> [core/daemonize.c:303]: daemonize(): Main process exited before writing to pipe And here's the routing block in kamailio.cfg. What I need to do is get the username for all non-expired contacts in the "location" table, perform a query on another database for each one of them and store the result in an htable: event_route[htable:mod-init] { sql_pvquery("ck", "select username from location where now() <= expires", "$avp(registered_ng)"); $var(i) = 0; while ( $(avp(registered_ng)[$var(i)]) != $null ) { sql_pvquery("ca", "select property from tablename where username = $(avp(registered_ng)[$var(i)])", "$var(ng_property)"); $sht(isnguser=>$var(ng_property)) = 1; $var(i) = $var(i) + 1; pv_unset("$var(ng_property)"); } pv_unset("$var(i)"); } Any hints as to what I might be doing wrong? Thanks! Best regards, George

Regarding ASYNC module in kamailio - handling SIP replies
by Rajagopal Maddi 02 Oct '17

02 Oct '17

Hi, We are checking the kamailio source code for the ASYNC module. The system is working for REQUEST_ROUTE, but not for REPLY_ROUTE. We added the ANY_ROUTE in the cmd_export_t, but still the async_route is not able to suspend for SIP Reply (For example, 401 - Unauthorized). Can we get some help on how to perform this. Some hints on how to perform would really help our development. static cmd_export_t cmds[]={ {"async_route", (cmd_function)w_async_route, 2, fixup_async_route, 0, REQUEST_ROUTE|FAILURE_ROUTE|ANY_ROUTE}, {"async_sleep", (cmd_function)w_async_sleep, 1, fixup_async_sleep, 0, REQUEST_ROUTE|FAILURE_ROUTE|ANY_ROUTE}, {"async_task_route", (cmd_function)w_async_task_route, 1, fixup_async_task_route, 0, REQUEST_ROUTE|FAILURE_ROUTE|ANY_ROUTE}, {0, 0, 0, 0, 0, 0} }; Regards, RajaGopal Maddi
