[Asterisk-Users] Cisco and Asterisk

[Tomasz Bukowski]

Hi!
First of all , (apart from solving your problem) you really should get
rid of the whole [demo] context from extensions.conf, and place your
stuff in your own context (i.e. [local]) (just for convenience and
"security"). Getting back to the problem - as I see it you want to dial
out through Cisco gw by dialing 1XXX
To do so you must send the whole number to the gateway, so the gateway
could do something (anything) with it.
Your extensions.conf should be more like:
exten => _1XXX,1,Dial(SIP/${EXTEN}@voice-gw)
Dialing 1602 on your system-phone will result with sending the number
1602 to the gateway, which will then (according to your current
dial-peer configuration) strip the leading 1 and send 602 back to
Asterisk to dial your laptop.
Hope it helps
Brgs
Tomek
