[Freeswitch-users] No VoIP audio after upgrading to latest svn

[John Wehle]

Yet more information ... a packet trace of a openzap to Grandstream
call shows:

  Source        Destination      Packet

  FreeSWITCH    Grandstream      SIP Request: INVITE ...

  Grandstream   FreeSWITCH       SIP Status: 100 Trying

  Grandstream   FreeSWITCH       SIP Status: 180 Ringing

  Grandstream   FreeSWITCH       SIP Status: 200, with session description

  FreeSWITCH    Grandstream      SIP Request: BYE ...

  Grandstream   FreeSWITCH       SIP Status: 200 OK

The interesting thing is I don't see the Grandstream attempt to send
audio.  Is there something that FreeSWITCH needs to say to the Grandstream
in order for the phone to send audio?
