Original configuration of Mitel 5000 fed by a PRI over copper- Smart Jack.
Issue 1:
Moving to SIP using an Adtran 908e SIP to PRI interface for the Mitel.
I can add a route for a DID going to an extension and it rings the extension, can answer the call and two way audio works.
If I route the DID to the Auto Attendant, if it goes to one that plays a recording, The application answers but no recording will play. The line just stays open and silent - not quite sure it if answers, just have silence on the line.
If I route the DID to a location that plays no recording but times out immediately to a Hunt Group, the phones ring and can be answered, but then there is no audio either way.
Does anyone know what kind of settings I need on the 908e PRI/T1 so these things work ok? What is different between the carrier's copper PRI from a smart jack and the PRI from the Adtran?
I set the Adtran to use ISDN AT&T 5ess, which is the way the Mitel is configured to talk to the smart jack PRI. The Adtran PRI is set for 24 channels. All PRI settings are left the same when testing the PRI from the Adtran. Using B Channels on the PBX. Frame settings are the same.
Issue 2:
When calling in DID routed to extension, rings and is answered, there is a high pitched tone on the calling phone. Two way audio works but the tone is only heard on the calling phone.
Issue 3:
When dialing out from an extension after 6 digits are dialed, the phone display goes to "enter extension number" and the dialing for the outside call stops.
All of the above work fine when connected to the carrier's PRI.
Does anyone know what the PBX is looking for, what I need to set on the 908e?
Is it incoming dialing plans, additional info the PRI needs to send, etc.?
I have one dialing subsitution - The SIP carrier sends 11 digits so I remove the 1 and send 10 digits to the PBX, which allows me to call in and get this far.
Thanks.
