    14 '''PJMEDIA allows different modes to be used for TX and RX''', and it obeys the '''fmtp mode''' that the remote party wants to receive and that it indicates in the SDP that it sends. However it is possible that remote endpoint doesn't support different mode for TX and RX and only wants to transmit or receive a specific mode that has been hardcoded or is specified in its settings. 
     14'''PJMEDIA SHOULD allow different modes to be used for TX and RX''', and it obeys the '''fmtp mode''' that the remote party wants to receive and that it indicates in the SDP that it sends. However it is possible that remote endpoint doesn't support different mode for TX and RX and only wants to transmit or receive a specific mode that has been hardcoded or is specified in its settings. However there is this ticket #40 which prevent iLBC session to work correctly when local and remote endpoint has different iLBC mode.

    1616To verify whether this is or isn't the case, you can experiment with changing the iLBC mode that is used by pjsua with using '''{{{--ilbc-mode=20}}}''' or '''{{{--ilbc-mode=30}}}''' command line argument. This will change the mode preference that is advertised by PJSIP in the outgoing SDP.
