Clone nortel extension to cisco wireless ip phone ?

Hi. We've deployed spectralink wireless phones to a few of our hospitals & now looking for a standard. We're doing a bake-off between a few vendors but the main players seem to be spectralink and cisco. Our voice guys are really leaning towards the spectralink for a couple of reasons, the primary being because we have so far not come up with a way to clone a users primary (nortel) desk phone to the call-manager-based cisco wireless phones.

Is there any way to do this? The incoming call should ring both nortel desk set + cisco wireless. It should busy/NA forward to nortel VM.

FWIW, apparently the spectralink product's gateway appears as some nortel option to the nortel switch so normal nortel optioning applies and they can 'clone' nortel-> spectralink.

Just wanna be sure our cisco's get a fair shake.

Thx.

Re: Clone nortel extension to cisco wireless ip phone ?

The only way you can configure an IP phone to have a shared line with a 'legacy' phone is via an MGCP gateway with an FXS port.

So, basically what you will see is the analog phone and the IP phone ring at the same time.

If you can somehow get the Nortel PBX to link up to the FXS port and ring the destination phone when the FXS port sends the ring voltage, it should work.

we are doing this with a Definity G3 and Cisco CM and 7960's.the router is set up as an H.323 gateway. When the legacy phone rings so soes the corresponding IP phone. It FNA's to audix.

We have a T1 between a Definity and a Cisco router.

alot of the config has been left out but you get the idea.

So on each G3 line that also has an IP Phone there is a bridged line configured. When the legacy phone rings it sends the call also to the T1 and the ip phone rings. so for legacy line 2116 when it rings so soes the ip phone with X 3116, the same with 2117 and 3117. If the appearance must be of the same number that is easily done also. This has been in place for almost 3 years and there are some minor issues but it works.

Re: Clone nortel extension to cisco wireless ip phone ?

This is a good solution since it uses the G3 to ring both endpoints. (and perhaps the Nortel PBX can do the same thing)

On CallManager, as it works today, you cannot ring an offnet destination and an onnet destination at the same time. Because of this limitation, you may not be able to accomplish what you want to with a Cisco wireless phone solution unless the Nortel PBX is simultaneously ringing the legacy phone and sending an inbound call to CallManager.
