We're implementing Exchange 2010 UM, and using a Dialogic Gateway for comm with the 2400. Thought we had it nailed, but hit a snag:

Outside calls to our 10 digit direct lines do not make it to the mail account. Here's the kicker. If the ACFS command is set to All FWD, it works. But when we adjust it to the normal setting, i.e. busy, or ring-no-ans, the call goes to the auto attendant.

I'm the middle man between my phone vendor and Exchange vendor. Just trying to figure it out.

Any ideas? I can get you more detail if it will help.

Thanks,
Bill

Answering my own question, here's what we get from NEC:
______
Techs are trying to present information across Q-SIG in a forwarding condition. This feature is called Q-10 Forwarding Station Information is supported in S03 and higher software.
Not supported in R20E. See below:


[Q-10] Q-SIG FORWARDING STATION INFORMATION

1. GENERAL DESCRIPTION

This feature allows a forwarding destination node to be notified the Intermediate Station Information (Station
Number, Call Forwarding Type) on inter-node Call Forwarding - All Calls [C-5]/Busy Line [C-2]/Donâ??t Answer
[C-3]/Logout/PS Incoming Incomplete [C-155] calls. The forwarding destination node is notified the information
through the Q-sig network, the tandem connection of Q-sig networks, and the tandem connection of CCIS
and Q-sig networks.
_____________

Unfortunately, we're at R20E. It's not supported.

Interestingly, as my OP states, All-FWD was working. It was only the Busy/Ring-No-Answer FWD that wasn't working.

Wish me luck on other options!

Cheers!
Bill
 

You should set up a station side T-1(24DLI) to a SIP gateway and utilize the MCI Link. I set this up about a year ago. I believe the maker of the gateway was Audiocode. Both the T-1 and MCI connect to the gateway.
  

That's encouraging. Perhaps we'd have better luck with an Audiocode Gateway. Everything else sounds similar to what we have in place.

Do you recall if you were beyond R20E on the NEAX 2400?

I'll run this by my vendors when they arrive today.

Thanks for the feedback.

Rev level of your PBX is irrelevant with this setup.  

Follow up: we ended up moving away from QSig. Went with a LineSide card, using CAS. This works through the Dialogic Gateway, and everything looks good.

Overall, quite a chore. Integration is a killer.

Thanks
