[SR-Users] kamailio crash

[Daniel-Constantin Mierla]

Hello,

I just tried with the same invite injected with protoshot and it works
ok. The relevant snippet of the config I used is:

$var(codecs)="G729,PCMA,GSM,iLBC,speex,telephone-event";
sdp_keep_codecs_by_name($var(codecs));
$du = "sip:127.0.0.1:9";
t_relay();
exit;

I could see that the sdp going out is also ok.

Therefore it might be specific to your config. Are you using other
functions updating the sdp before the sdp_keep_codecs_by_name()?

Cheers,
Daniel
