How can SIP VOIP be implemented with the Nortel key systems (non-BCM)

[TimSigafoose]

We are devising a plan whereby we can offer our customers true voice and data redundancy using a CLEC with an MPLS network and an MSO with a fiber/cable Sonic ring type network. What we need to address is how to get SIP traffic in and out of a variety of Norstar switches. This customer has switches ranging from a 308 to a 616 to an 824 to a MICS and either has T1's on channel banks or PRI depending on the location. If there is a Nortel device that will do it, I haven't been able to find it. Perhaps someone knows of a 3rd party device or devices that will do what we need?

no sip phones only IP trunks thru a gate way...many manufactures including Nortel

We've investigated this thoroughly, the only viable way is to have a SIP proxy with a PRI coming in and going out, setting up a dialplan on the nortel boxes to route a certain destination code via the PRI to the sip proxy, which would then route the call to the SIP phone.

There is zero interoperability with Nortel and any VoIP technology, with the exception of the incredibly expensive Nortel VoIP adapter, which is nothing more than a way to bridge two systems via IP(h323 at that).

We ran into this situation where we wanted to take a few lines and have them go to a voip solution.
we went to

and got a smartnode with 4 ports so that we could interface the system with a sip server.
this however is not the best solution.
you need analog extensions to get it to work.

I'm not a phone guy, but what we use is is a MCK IP Gateway this device allows use to connect up 8 pure VIOP phone or, as we use it we have a user located out of state she has a IP Gateway on her end that allows her Phone which is not an IP phone to connect. If someone calls her they enter her extension and she answer the caller has no idea shes not in the office. again I'm the network guy but I set this up and it was very simple. the website for this is

The MCK gateways are pretty cool for that application. They run directly off a digital ext port from the ksu, they're simple to install (provided you know how to terminate a 25pr amphenol), and our customers love them.
