Can CME 4.0 work with Nortel Meridian Digital PBX? We would like to install CME 4.0 and connect it to this Nortel PBX. The phones that are connected to Nortel PBX are digital phones.We are replacing all the office phones with Cisco IP Phones. The warehouse phones will remain analog with cat3 cabling and overhead paging that uses cat5e. How can we make this work?
Thanks for the response. I dont have a separate GW. How can I connect the Cisco 3845 CME Router to the Nortel PBX. Do I connect it to the FXO port? or add a T-1/E-1 module on CME Router? I read about QSIG but not sure how to implement it.
If your Nortel PBX does have any IP integration, then you can create a MGCP/H323 trunk. But I think that the best way to join your CCME with that PBX is using FXO ports, or an E1 interface to get 30 channels.
You'll need an E1 interface in each device(PBX, GW).
and you must configure dial-peers to be able to call to the analo phones that will be connected to the PBX.
Thanks for the info. Do I need a separate GW? Or can 3845 router accomodate the E-1 interface card? Both the PBX and the Router are located in the same Closet. Also I would like the extensions on PBX system to use the CUE on CME. Is that possible? are there any issues with call transfer etc...?
Can I have part of the extensions say 211 till 255 on CME and 266 till 299 on the PBX?
Have a T1 or TMDI card in the Norstar to take a T1 connnection to the CME. In the CME add a T1 module and then configure routes in Norstar to be routed to the CME. Configure the ISDN switch type to be the same as in the Norstar (Probably DMS100). If the routes are configured correctly, there wont be any issues in call transfer. You can have 4-digit dialing between the Nostar and CME.
I am not sure about CUE voice mail for PBX extensions. My belief is its not possible, since we have to create users and extensions in CUE for voicemails and it should be present in the CME. If the extensions are present as ephone-dns in the CME, then the call routing between the Norstar extensions and CME extensions wont work.
You can have any combintion of extensions on Nostart and CME (without duplication) and the routes are built correctly in Norstar.
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
