[Asterisk-Users] Delay on outgoing calls

[Stefano Arata]

Hi, I've a wildcard TDM400P card with 2 fxo and 2 fxs modules. 
I've set this extension in my extensions.conf for obtain the external
line:

exten => 0,1,Dial(Zap/g2,10)

The dial application is executed immediatly but next this there is a
delay before I can hear the tone.
This is the output in the CLI:

    -- Starting simple switch on 'Zap/1-1'
    -- Executing Dial("Zap/1-1", "Zap/g2|10") in new stack
    -- Called g2
    -- Zap/3-1 answered Zap/1-1
    -- Attempting native bridge of Zap/1-1 and Zap/3-1

The delay is about 2 seconds and it is between "Called g2" and "Zap/3-1
answered Zap/1-1".

Where can I reduce this delay? I have tried to find it in zaptel.h, but
I'm not sure if it is in the driver sources or in the asterisk sources.

Thank you in advance,
