is there a way to force h264 packetization mode 0 or 1 in freeswitch? running into an issue where a-leg h264 uses mode 1 but freeswitch sends mode 0 to b-leg. I've even tried disabling transcoding, and sending exact same A leg codec string to b-leg, and still, freeswitch uses different packetization mode. Any advice would be appreciated! Thanks
