MiVoice Office 250/Mitel 5000 / Re: Adtran PRI to Mitel 5000 Auto Attendant recordings won't play

Thanks for the reply.

Yes the issue was the switch type.

The Mitel was orginally set to AT&T 5ESS, so I set the Adtran to the same.

I changed then Adtran to ISDN NII2 and then things worked properly.

When going to auto attendant, it would immediately answer and the Connect messages would start before the other data which when ringing an extension the Connect would be after this data. The messages were different, apparently the Mitel would not process things because of this.

It works with the Mitel still set at 5ESS, but changed that also to match.

As far as the noise - changed test phones and it went away. Start with simple things first.

MiVoice Office 250/Mitel 5000 / Adtran PRI to Mitel 5000 Auto Attendant recordings won't play

Mitel 5000 fed by a PRI over copper.

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 STAR applications, if it goes to one that plays a recording, The application answers but no recording will play. The line just stays open.

If I route the DID to a STAR 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 the Mitel needs from the PRI 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 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.

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 Mitel needs?
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 Mitel, which allows me to call in and get this far.

Thanks.
