> When I dial a channel with an endpoint that prefers iLBC mode 20 the SDP from asterisk offers mode 20. If the endpoint replies with ans SDP that iLBC mode 20 is accepted and sends RTP packets according to spec, then the CLI reports a warning stating "[2019-12-20 17:59:59] WARNING[2512]: codec_ilbc.c:125 ilbctolin_framein: Huh?  An ilbc frame that isn't a multiple of 50 bytes long from RTP (38)?". iLBC mode 20 packets are not in multiples of 50 rather they are 38 bytes long. So the correct packets are being sent and rejected in error by asterisk. This behavior is only present in outbound channels dialed to the the endpoint. 
> If the called endpoint replies in their SDP that they want iLBC mode 30 everything works just fine.
