Hi All,

I am trying to integrate FreePBX with A2Billing but i got stuck in the final step, redirecting a incoming DID call from FreePBX to A2Billing.

I setup FreePBX and all seems to be good there I could setup and use extensions, make calls out to landline phones, reciving calls through my DID and redirecting it to a FreePBX extension. All running fine with no issues.

I setup A2Billing as per a tutorial I got:

1. Created a provider
2. Created a trunk (Using the same trunk I created and tested in FreePBX)
3. Created a call plan and rates
.....

Then changed in FreePBX the incoming route to point to I tried with all other options (A2Billing - Callthrough and A2Billing-ANI Callback and got the same issue)

Ok now the issue that i am having is:

When I call to my DID then the call just hangs up and I can see this line in the FreePBX messages logs:

Channel 'SIP/-00000051' sent to invalid extension but no invalid handler: context, exten,priority=a2billing-did,s,1

Hopefully someone could help me here.

Hi

Your a2billing-did context will have an extension pattern match like _X. which matches numbers, but does not match the "s" you are currently sending, hence the error message.

"s" is delivered if you have a catchall in inbound routes, e.g. leave the DID blank, it's better to have _. (underscore dot) in the catchall for the DID, as this will ensure the DID number is sent on to the a2billing-did context.
