everything above 60 ms is a nonsense ... and ugly :) It screws your voice
quality not even thinking VBD (voice band data) over that line :).

Anyhow, Nikolay, your problem is broken IPO h323 stack and the know avaya
"flexibility" when interoping with other vendor equipments. Here IPO is
unable to negotiate a different framing size than the default and sadly this
is the core of the problem.

Please, can you send me two tcpdump captures of calls between IPO and FS:

   1. a capture with fast start & h245tunneling=true
   2. a captire with fast start & h245tunelling=true + h245inSetup


I just want to be sure of something.
