I think L16 stereo will work out of the box with pjsip compiled in stereo mode but that's the only one. If I recall correctly, Speex has varying packet lengths, so its not practical to append the encoded left and right channel data in an RTP packet, because the receiving endpoint will not be able to separate the channel data prior to decoding, not easily anyway. You can use a codec which has a constant encoded packet length or you can add additional structure to the RTP data to be able to separate the channel data, but then it's non-standard packet data.
