I'm afraid (well, I'm pretty sure) non of them want to do it, because
they need very accurate billing and this is simpliest way how to do it -
kill calls without RTP i few seconds.

Yes, I know. I have spent some years with * in the past (from "pre 1.0"
release if I remember correctly :-).
In my post I mean * ability to send faked audio during recording:
transmit_silence_during_record=yes option in asterisk.conf

None of my TSPs use Asterisk :-)
Around me there are much more popular Cirpacks and Phonets - due to
scalability, features, SS7 support etc...

Thanks once more, Chris, for your interest!
