Hello,
already tried this one?
https://kamailio.org/docs/modules/5.5.x/modules/sdpops.html#sdpops.f.remove_...
Hi - i need to _add_ :) so more like: (it works, but it looks like a 13 year old me - programming in BASIC on 8 bit Atari)
if (is_method("INVITE") && search_body('a=rtpmap:[0-9]+ telephone-event/8000')) { xlog("L_INFO","DD BlahFIX: found CID:$ci\n"); if (! search_body('a=fmtp:[0-9]+ 0-15')) { xlog("L_INFO","DD BLAH2 FIX: not found fmtp: CID:$ci\n"); subst('/a=rtpmap:([0-9]+) telephone-event/8000/a=rtpmap:\1 telephone-event/8000\r\na=fmtp:\1 0-15/i'); rewritehostport("172.23.133.4:5062"); ## loose_route();
} }
but - maybe someone already has this issue, rtpengine and remove codecs and rewrite them and do RTP anchoring - too much, overkill for this simple task,
as -> 'a=fmtp:XXX 0-15'
is not a mandatory in SDP, and XXX is dynamic, so 1st i search for telephone-event, use ( ) and \1 group in RE, and then - add static text, but it looks like i'm reinventing something that is common with some broken scenarios / end-points that insist on having rtpmap ant fmtp for well-defined codecs / payloads.
