Hi,
from the RTPEngine Docs:
The following codecs are supported by/rtpengine/:
*
G.711 (a-Law and µ-Law)
*
G.722
*
G.723.1
*
G.729
*
Speex
*
GSM
*
iLBC
*
Opus
*
AMR (narrowband and wideband)
*
EVS (if supplied -- see below)
Codec support is dependent on support provided by the|ffmpeg|codec
libraries, which may vary from version to version. Use
the|--codecs|command line option to have/rtpengine/print a list of
codecs and their supported status.
what codecs are being offered in the SDP?
did you compile RTPEngine or use a package? have you installed the
correct codecs via compiling options or packages?
