I'm trying to do wholesale business with some dozen of interconnects.
It's hopeless to force all customers/clients to use the same ptime - and
I think there is no real reason to force them. I'm already happy, if
they all offer the usage of g729 ;-). Often they pass through the calls
themselves.
BTW - I never understood, why 20 ms is the default frame size. In this
way you have about 20 bytes payload and 40 bytes overhead for the TCP/IP
header, which is a pretty bad ratio.
