asterisk users - Mar 2006 - I don't listen first seconds of audio from call - Asterisk integration with old PBX

Hi all,

i have:

out side PSTN-------->OldPBX---------Analog----->Asterisk (X100P)
                                  ^
                                  |
                               Local Ext

What is happening is:

Calls from Local ext goes to Asterisk and everything is fine.


Calls from Out side PSTN reach the OldPBx and are bridged do Asterisk,
but i don't listen firs audio seconds of autoattendant:( but after
that every think works well).

I've tried to put a Wait(6) on Asterisk after Answer() and it solved
the problem... but i really wouldn't like to wait 6 seconds :(

Any suggestions?

Best regards,
Marco Mouta
