Hi to all,
I am configuring inbound calling using DID: all works correctly (agi debug presents no errors, destination phone ring correctly, the call goes on), but the caller can't listen the tone while the destination phone is ringing.

Where should be the problem ?

I am using this config:

sip.conf:
[general]
context=a2billing-did

extensions.conf
[a2billing-did]
exten => _X.,1,deadAGI(a2billing.php|1|did)
exten => _X.,2,Hangup

Thanks
Valerio

To be certain where the problem lies you'd need to carefully analyse the SIP transactions.
That said, if you read the comments in a2billing.conf relevant to the dialcommand_param directive then you should see a way to ameliorate the problem.

I seen "r" and "R" parameters: I am using it...

I will investigate more...

Thanks
Valerio

Hi stavros.

this is the dial command:

AGI Rx << EXEC DIAL SIP/XXXXXXXX|30|hRrl(3600000:61000:30000)

What do you think ?

Should be possible to take inbounds calls without using Dids, but using the Caller ID list in Card definition ?

Thanks
Valerio

I didn't initially notice that you were lacking a 'Ringing()' in your dialplan. Try this:

That doesn't tell us anything about what the caller should hear. Just today I had to debug a similar issue to yours with a DID supplier: everything worked, except the caller didn't hear ringback tone at all. With Wireshark I was able to prove to the DID supplier that we were sending 'Trying', then 'Ringing' but we still weren't hearing ringback when calling the DID via different carriers (BT, Vodafone, etc). After presenting them with this proof they had the problem fixed within 20 minutes.
Of course using Wireshark there's also a chance you'll prove the problem is in your own configuration, but that is useful knowledge.

Not that I know of. Your customers can only receive inbound calls from A2B by using the DID feature. Or were you asking something else?

Ok: a good idea. Tomorrow I will try with wireshark.

No, I though this: but what is the meaning of Caller ID in card definition ? How I should use it ?
Thanks
