Asterisk 1.2 will use a T1 timer (retransmit) based on the 'qualify' 
time, if have that turned on for the peer. The INVITE will be 
transmitted a total of six times (per the RFC, IIRC). If your peer is 
_close_ and responds quickly to qualify packets, then the total INVITE 
timeout could be a second or two at most.

There is an open feature request to make the T1 timer adjustable on a 
per-peer basis, but nobody has had the time to implement it yet.
