I can't receive calls

#1

I have tried literally every configuration of the provider extensions in sip.conf, but cannot find out how to
receive calls: every time I receive the following error:

Blockquote [May 15 18:16:22] NOTICE [4705][C-000000ec]: chan_sip.c : 26512 handle_request_invite : Call from ‘asterisk’ (192.168.2.1:5060) to extension ‘FritzBS’ rejected because extension not found in context ‘incoming_TIM_BS’.

I have an extensions FritzBS which has context=incoming_TIM_BS SO, why the hell asterisk is saying that I don’t have it???

#2

Have you configured the context in extensions.conf with something that would match it?

#4

Outbound calls are working like a charm, while incoming calls are not

#5

Define an extension called ‘FritzBS’ in your ‘incoming_TIM_BS’ context. Your pattern match is not matching because the extension does not start with a number.

#6

Could you please be clearer?

Is sip.conf I already have [FritzBS]. How should I modify the [incoming_TIM_BS] context in extensions.conf?

If I change _X. with FritzBS

[incoming_TIM_BS]

exten => FritzBS,1,NoOp()
same  => n,GoTo(cellulari,matejipad,1)
same  => n,Playtones(congestion)
same  => n,hangup()

I get this log:

Now it is working!!:grinning:

[incoming_TIM_BS]

exten => FritzBS,1,NoOp()
same  => n,GoTo(cellulari,1003,1)
same  => n,Playtones(congestion)
same  => n,hangup()

I exchanged “matejipad” with “1003” and now I receive calls!!

Last problem: when I answer to the incoming call and then hang up, call from caller side doesn’t and continues:

#8

Last problem: when I answer to the incoming call and then hang up, call from caller side doesn’t and continues

How to solve it?

It this way, hangup works perfectly
