Guys, hope you can help.

I have a 3com NBX 100 connected to a 2811 using QSIG. I have most things working. Calls between the 3com and CUCM are fine. The DN shows up on both phones. However neither system show the calling name on the phones. I am not sure if the NBX supports this. I have tried both H323 and MGCP and the results are the same.

I was hoping one you guys have came across this scenario and perhaps could shed some light on it.

Thanks in advance,

More advanced QSIG features, such as Calling Party Name, are not supported.

Today the 3Com NBX doesn't run with IP/Phones but only with MAC Ethernet Phones (NBX proprietary).

The current NBX services are:

Voice mail

Call attendant

Conference (4 groups of 4 users)

Unified messaging with an Advanced PowerMail Exchange\APX interface

We have also UCME 8.1 (3945-E) that I'm trying to connect to 3com NBX V5000 through QSIG.

The 3com phone rings from Cisco phone but there is no voice.

Grateful if you can post some configuration here. We are using Cisco switches.
