> Valid payload type codes are between 0 and 127 to allow for being stored in 7 bits.  During call setup, pjsip validates the SDP and will assert if it encounters an invalid payload type code (see pjmedia_sdp_validate() in pjmedia/src/pjmedia/sdp.c).  This assert will be hit if a call is placed to a pjsip endpoint with allow=all set.
