[Asterisk-Users] Easy question? Get started with the Demo

Wed Dec 15 03:31:15 MST 2004

Hello, I’m trying to get started with asterisk/SIP so I was trying the demo
that is provided in the extensions config file, but the call isn’t
“answered” by my server when I try calling the number that I registered at
my SIP provider.

I’ve registered with register => John.Doe:MyPass:MyUser at my-sip-provider in
sip.conf and if I use “sip debug” I can see the call is coming in but then
nothing more happens (see debug output below).

Sip.conf:

[general]

context=demo

[wx3.se]

type=peer

fromuser=MyUser

secret=MyPass

fromdomain=my-sip-provider

context=demo

extensions.conf:

[demo]

;

; All the stuff in the demo

;

exten => s,1,Wait,1                     ; Wait a second, just for fun

exten => s,n,Answer                     ; Answer the line

exten => s,n,DigitTimeout,5             ; Set Digit Timeout to 5 seconds

exten => s,n,ResponseTimeout,10         ; Set Response Timeout to 10 seconds

and so on

That’s all I have
have I missed something?

Debug output from call:

192.1.1.1=my server

0123456789=my number at SIP-provider

9999999999=the number I’m calling from

213.132.103.213, 212.112.162.50=my SIP providers IPs
