[Freeswitch-users] unable to set up a call using speex

[Michael Jerris]

Dynamic payload range is 96-127.  Codecs below 96 are assigned to specific codecs so would only match if 84 is assigned to speex, which it is not.

See the IANA assignments for pt here:

It seems like freeswitch, which is using dynamic payload 99 for speex is unable to match that up to the fact that the remote side (client) is using payload 84.  If so, this would seem to be a bug.
