[Asterisk-Users] voice delay after call setup, outgoing calls

[David Hajek]

Hi,

I'm experiencing some voice delay (2-3 sec) after outgoing call is setup. It
means during the first 2-3 secs, audio is very choppy or nothing. So usually
I can't hear the 'Hello".

I use IAX2 for my ougoing calls with Grandstream phone as a client. Any
hints to prevent this? 

Thanks,
David
