In master branch there is already subst_body(): - https://github.com/kamailio/kamailio/blob/master/src/modules/textops/textop… I will add more as I get time before 5.1 release. Anyhow, even in 5.0 is a generic kemi function that allows executing any kamailio.cfg function, respectively: KSR.x.modf(func, param1, ...) In your case, try: KSR.x.modf("replace_body_all", "a=sendonly", "a=sendrecv") You should be careful with KSR.x.modf(...), because is some cases it may result in pkg leak due to cfg param fixup. So, do some tests and be sure that pkg memory stats are not indicating a leak.

rtpengine_manage in tsilo INVRESUME sends delete instead of offer
by Anthony Alba 06 Oct '17

06 Oct '17

Hi, I am using tsilo and push notification recipe from https://www.kamailio.org/events/2015-KamailioWorld/Day2/20-Federico.Cabiddu… On resume of a suspended transaction rtpengine_manage() is sending delete instead of offer. In the routing block INVRESUME after t_continue(): route[INVRESUME] { lookup("location"); rtpengine_manage("DTLS=off ICE=remove"); t_relay(); ts_store(); $sht(vtp=>stored::$rU) = 1; } I expect rtpengine_manage() to send offer since this is a Request+SDP; instead it sends delete to rtpengine with garbage Call-ID. If I replace rtpengine_manage() with rtpengine_offer() then it works. rtpengine (the actual media proxy) sees Received command 'delete' from 192.168.1.755:49851 Call-ID to delete not found which is totally bogus of course. rtpengine_offer() works fine but wondering why rtpengine_manage() goes berserk here.

rtpengine - optional srtp
by Daniel-Constantin Mierla 06 Oct '17

06 Oct '17

Hello, wondering if anyone has a quick answer to spare some time searching the web or source code -- is there a way to offer optional SRTP (just SDES is also fine) in SDP with RTPEngine? The use case is when the target device is not yet known to support (or not) SRTP. There are couple of ways in specs or practices (e.g., RFC5939/6871, or advertising crypto attributes on RTP/AVP stream, or offering two streams one RTP and one SRTP), I am looking to find if it is possible to do it with RTPEngine and which of the options are supported/what are the parameters for doing it...

A "success_route" as counterpart to "failure_route" available?
by Kristijan Vrban 05 Oct '17

05 Oct '17

Hello, i need a "success_route" which does the same as "failure_route", but only for positiv 2xx reply. Is something like this available? Background: i forward REGISTER to external registrar server, and only what to save the location on positiv reply to REGISTER. Without doing the authentication myself. I tried to save the location in onreply_route, but then the contact of the external registrar server is saved. So i need a status check in the REQUEST_ROUTE. Best Kristijan

04 Oct '17

I am trying to setup the internal XCAP service and kamailio will not start. The messages log states "kamailio: CRITICAL: <core> [cfg.y:3372]: yyerror_at(): parse error in config file //etc/kamailio//kamailio.cfg, line 1009, column 1-11: syntax error" This is the line "event_route[xhttp:request] {" from the config file. I am not sure why this is happening any ideas? Thanks,Jim
