[Asterisk-Users] rtpmap issue w/Grandstreams

[Glenn Dalgliesh]

Sent this to grandstream support but has anyone else seen this issue. All of
the previous sdp rtpmap are correct until the grandstream sends this. I have
been using disallow=gsm and canreinvite=no to get around the problem.

I am seeing ATA-286, running Program--1.0.4.55, send and INVITE message with
rtpmap:3 PCMU/8000. 3 is a well-known port and should be mapped to GSM not
PCMU. 162.33.165.203 = HandyTone ATA-286162.33.165.198 = Asterisk     SIP
