[Freeswitch-users] Help with choppy audio after attended transfer

[Chris Cureau]

Latest git doesn't help unfortunately.

More research is beginning to confirm its a codec issue.  When I limit the
phone to codes that use 20ms packetization, I hear no incoming audio on
outgoing calls.  Incoming calls are okay.  When using All for codes (and the
30ms packetization) I get the choppy voice when leaving MOH.
