Hello,

I don't know if this helps but I noticed you have a log entry:

Unknown flag encountered: 'force'

This is because rtpengine does not support this flag any more, it's mentioned in the rtpengine module documentation: http://kamailio.org/docs/modules/devel/modules/rtpengine.html#rtpengine.f.rtpengine_offer

You may want to try rtpengine module instead of rtpproxy-ng module, this is just a guess but hopefully a good one.

I wonder do you have changes in Asterisk side? In my case changes in Asterisk realtime table changed the behavior concerning sdp, you may want to check that on your sip traces. In my setup Asterisk changed the sdp but I'm not sure if this applies to your case.

I hope this helps any.

cheers,

Olli

I don't know if this answers your question, but you may not see the
changes to the SDP body within Kamailio until you call
msg_apply_changes() or actually send the message back out.

cheers
