which will not work in the situation as benny wrote, when the primary
peers doesnt answer to any request coming from asterisk. so you will
have an 30 second timeout.

what i mean is the Sip internal timeout how long a peer is able to
answer to this sip packet, which per default is 30 seconds.

if you set the dial timeout lower than this sip timeout you will have a
lower waiting time, but as benny said, if the client answer too slow its
not handy to use.

i made a mistake in asterisk ver. 1.6.2.b2 you are able to setting the
sip timers of your own see the sip.conf sample from this version below:

;--------------------------- SIP timers
----------------------------------------------------
; These timers are used primarily in INVITE transactions.
; The default for Timer T1 is 500 ms or the measured run-trip time between
; Asterisk and the device if you have qualify=yes for the device.
;
;t1min=100                      ; Minimum roundtrip time for messages to
monitored hosts
                                ; Defaults to 100 ms
;timert1=500                    ; Default T1 timer
                                ; Defaults to 500 ms or the measured
round-trip
                                ; time to a peer (qualify=yes).
;timerb=32000                   ; Call setup timer. If a provisional
response is not received
                                ; in this amount of time, the call will
autocongest
                                ; Defaults to 64*timert1
