Description
Currently, pjsua will do asymmetric iLBC mode when SDP offer answer specify different iLBC mode.
RFC 3952 Section 5:
It is important to emphasize the bi-directional character of the "mode" parameter - both sides of a bi-directional session MUST use the same "mode" value. The offer contains the preferred mode of the offerer. The answerer may agree to that mode by including the same mode in the answer, or may include a different mode. The resulting mode used by both parties SHALL be the lower of the bandwidth modes in the offer and answer. That is, an offer of "mode=20" receiving an answer of "mode=30" will result in "mode=30" being used by both participants. Similarly, an offer of "mode=30" and an answer of "mode=20" will result in "mode=30" being used by both participants.
