Guillaume,

It is intended that OPAL should provide the same mechanisms for using an
external RTP stack as OpenH323. The current OpenH323 API is documented at
http://www.voxgratia.org/docs/external_rtp.html

We've not yet had the time to make the SIP code within OPAL conform to this
API. Perhaps you could assist in this?
