[Spce-user] Transcode Audio Codec and preferred vocoder list

[Raúl Alexis Betancor Santana]

Thats because SCPE doesn't touch the RTP at all ... it only proxy it if needed, but don't do any transcoding. 

If you whant transcoding or more advanced RTP tricks ... you should play with the SEMS part of SPCE.

> Hello,

> Thanks for you help.
