asterisk

Not getting any incoming call notification, nor is the dongle answering up the call

I am trying to get asterisk to configure and answer incoming call. This is just the first step towards the development. Once the modem picks up the call I will start developing the dial plan. Please review my conf files

  • the status does not change when I make incoming calls. Ideally 'Incoming' should increase. It does not.
  • dongle sms dongle0 +911234567890 hi, the sms is sent and it works
  • dongle cmd dongle0 dongle cmd dongle0 ATD+91123456789T;, this works, the outbound call happens
  • dongle cmd dongle0 ATSO=1; goes through, but calls are still not picked up at all. Ideally should pickup after 1 ring.

What am I missing in the config ? I know its something small and silly.

Solution

  • After doing a lot of trial and error. I finally fixed the issue. The dongle.conf had to be changed to audio=ttyUSB1 and data=ttyUSB2. This only got to the stage of the incoming call notification coming in. From then on, the dongle.conf needs one more change. The context needs to point to your helloworld in extension.conf. So I created a context=dongle-incoming. In the extensions.conf I put in 

    [dongle-incoming]
exten => s,1,Answer(500)
exten => s,n,SayPhonetic(hello to taxeeta)

    Also in extensions.conf I put include=>dongle-incoming and removed include=>default.
