[SR-Users] kamailio with mediaproxy-ng, 488 Not Acceptable Here

[Klaus Darilion]

Hi!

The problem is different SDP formats between normal SIP 
clients/gateways, and WebRTC clients.

You have to instruct mediaproxy-ng to rewrite the SDP and do the 
conversion (encryption, ...).

So either the rtpproxy_ng calls lack the commands for the "gatewaying", 
or the webrtc clients uses eg. an encryption which is not supported by 
mediaproxy-ng.

Please also post the kamailio.cfg snippets when calling rtpproxy_ng and 
give details about your environment (browser, SIP client ...)

regards
Klaus
