Doesn't answer incoming call through Dahdi

Asterisk Asterisk Support
1

I’m trying to build a new PBX. I managed to install & configure the dahdi drivers for the hardware I’ll use for this test (Sangoma A101 + 1 port low end HFC-S)

AFAIKT I got everything OK, and I’ve started some preliminary tests with a spare BRI line. I see two different problems.

  1. Asterisk rejects calls if I don’t explicitly list my DID as an extension (i.e. special extension “s” does not work) here is what I see (phone nombers obfuscated):

== Primary D-Channel on span 2 up -- Extension '51601xxxx' in context 'incoming' from '335615xxxx' does not exist. Rejecting call on channel 0/1, span 2

  1. I put this code in context [incoming]:

exten => 51601xxxx,1,Answer() exten => 51601xxxx,n,Playback(vm-goodbye) exten => 51601xxxx,n,Wait(10) exten => 51601xxxx,n(end),Hangup()
then something starts working. On incoming calls, this is what I see on the console:

== Primary D-Channel on span 2 up -- Accepting call from '335615xxxx' to '51601xxxx on channel 0/1, span 2 -- Executing [51601xxxx@incoming:1] Answer("DAHDI/32-1", "") in new stack -- Executing [51601xxxx@incoming:2] Playback("DAHDI/32-1", "vm-goodbye") in new stack -- <DAHDI/32-1> Playing 'vm-goodbye.gsm' (language 'en') -- Executing [51601xxxx@incoming:3] Wait("DAHDI/32-1", "10") in new stack -- Executing [51601xxxx@incoming:4] Hangup("DAHDI/32-1", "") in new stack == Spawn extension (incoming, 51601xxxx, 4) exited non-zero on 'DAHDI/32-1' -- Hungup 'DAHDI/32-1'

But on the calling line, the result is the same that in the first case: after about 5-8 seconds of silence, the call is rejected (I hear busy from landlines, or rejected from GSM mobile). I can’t hear no ringtones, no anything else.

I’m new to asterisk, so I suppose I’m missing something: anyone has seen something similar?

Put a underscore (_) in your extension rules:

exten => _51601xxxx,1,Answer() exten => _51601xxxx,n,Playback(vm-goodbye) exten => _51601xxxx,n,Wait(10) exten => _51601xxxx,n(end),Hangup()

And try again.

Of course that changed nothing (the underscore is for wildcard matching, while the ID is exactly that)

Instead, I found out the problem is in the line I was using: I tested that same configuration with a different BRI line and it worked without changes. I wonder what kind of signals are different on the two lines, if I attach to them a true ISDN phone (S-BUS) it works fine on both lines.
