[asterisk-users] asterisk sip problem

[Emmanuel Favre-Nicolin]

Hi,

I'm having a problem to receive inbound call from my sip provider. I used to 
be OK, I may I have change something (for example I switched from asterisk 
1.4.20.1 to 1.4.21.1). Could that be a bug? (I doubt that and I guess it a 
configuration problem on my side!)

I have basically a sip account and a linksys voip adapter with a phone on it 
(sip name 1000), configured in asterisk. Outbound call from the phone just 
work fine. Inbound call fail to ring my phone. When the inbound call occur I 
see on the asterisk command line :

    -- Executing [17772962667 at from-callcentric:1]  
Dial("SIP/callcentric.com-081f1ac8", "SIP/1000") in new stack

    -- Called 1000

    -- SIP/1000-081ed5e0 is ringing

but my phone is not ringing

in sip.conf:

[1000]
type=friend
secret=blablabla
qualify=yes    ; Qualify peer is not more than 2000 mS away
nat=no         ; This phone is not natted
host=dynamic   ; This device registers with us
canreinvite=no ; Asterisk by default tries to redirect
context=fromsoftphone
port=5061     ; Uncomment this line if Ekiga and Asterisk are on the same host


in extensions.conf:
[from-callcentric]
exten => 17772962667,1,Dial(SIP/1000)
exten => 17772962667,n,Hangup()


The default extension I got for inbound call is 17772962667 that's why I used 
that extension. I tu
