Adtran 900e - Inbound SIP DID to FX0 and overflow to PRI

[mark_sss]

First post and new to Adtran so please forgive ignorance.

I have successfully configured our 924e to accept inbound DID SIP calls from our telco provider and hand them off to a PRI (that terminates into an ACD).  I have managed to assign some FX0 ports on the Adtran to have their own DID (setting the FXO extension number to actually be the DID) so that inbound SIP calls to those specific DID's ring the POTS phones.  However I have not been able to get "Call Coverage" to work so that if the POTS lines are not answered in 2 rings, the call is sent to a different number that routes down our PRI into the ACD.

My first biggest challenge was when going off hook on the POTS lines, to have the ADTRAN send the call over our SIP connection - by default it was always sending the call to our ACD over the PRI.  I had some help and managed to get the outbound POTS calls to go out our SIP lines by using "Least Cost Routing".  I am wondering if that is what is breaking the Call Coverage now.  Fiddling around I was able to get "Operator Assisted Calls" from the POTS to go to the PRI instead of over the SIP lines.  So on the POTS if I go off hook and dial a 10 digit number prefaced with a Zero, the call goes to the PRI - If I just dial a 10 digit number on its own, it goes out our SIP lines - which should work alright.  However when I put the 11 digit number (0-123-456-7890) into Call Coverage section of my extension, and make a test call - the extension rings twice and then goes to a busy.

Any help would be much appreciated.  If there are videos out there explaining how the Adtran 900e processes calls, that would really help too.  I've no doubt I'm missing a core concept or two on how these Classes of Service and Dial Plans all tie in with the different inbound/outbound call matrices.

Thanks in advance,

Mark.

Hi,

Checkout this document Source and ANI Based Routing in AOS Voice Products

If post your config I should be able to give more direction.

Thank you

Wow that was fast, thanks Unified!  I actually found that document while doing all my research but with my limited understanding in how it all ties together, it was a bit over my head.  I edited my config a bit for security's sake but the 1112223333 is my DID that comes in from the SIP carrier to the Adtran and rings the FX0 port.  The 04445556666 number is my 'operator assisted' number that I would like the Adtran to ring to when the DID is not answered on the FX0 port - I am using call coverage for that.  There may be a much better way to do this....
