PBX Interoperability: Nortel Communication Server 1000

Unanswered Question
Mar 8th, 2010


Is there any new document for "Cisco Unified CallManager Express Release 3.2 - PBX Interoperability: Nortel Communication Server 1000 Release 4.0
Using H.323 Trunk"

Is anyone of you aware of the following features supportive in new release of CCME 3.2

Limitations CCME 3.2
Called and Calling Name and Number are not displayed on Nortel phone when calling from and to CCME phone
Calling Number only displayed on CCME phone when calling from Nortel phone
Dialed Number is displayed on Nortel and CCME phones rather than Connected Number when calling from Nortel or CCME Phone
H450.2 and H450.3 supplementary services must be disabled and ”allow-connections H323 to H323” must be enabled on CCME to
support call transfer and call forward to Nortel, Nortel currently does not support H.450 Supplementary Services
Call Transfer and call Forward calls fail if Nortel phone executes call transfer or forward to CCME phone across H323 trunk
Full Blind Transfer call fails if CCME phone gets the call from Nortel Phone and executes the full Blind transfer to any phone



I have this problem too.

Most of these limitation appears to be on the Nortel site so either just try and see yourself, or us

e E1 PRI that is more standard than H.232.

I couldnt find the latest document for CME PBX Interoperability: Nortel Communication Server 1000, so I posted the request.

I thought with lastest CME version there should be an updated document for PBX Interoperability: Nortel Communication Server 1000
