Hi,

This may not be possible, but I thought I'd write and findout.

Currently we ave a NEC NEAX 2000 IPS PBX that uses Dterm Series phones
for the end user.  They are not satisfactory, and I was wondering if
there is a way to connect Cisco 7960 IP telephones to the NEC PBX?

If we have to buy a gateway, we would seriously consider doing so.

Thank you for your help and please feel free to ask me for any
clarification.

Thank you,

Tazzer

Try this:

It allows you to directly connect 8 IP phones to an NEC PBX.

Actually I am currently using this in my office to connect an 802.11b SIP
phone to an Avaya PBX and it works great. This unit handles all different
PBXs.

Depending on the IP phone though you might need to use a SIP Proxy though
but you should be able to locate an opoensource / free one or purchase one.
There are a few on the market that are not very expensive. You might even be
able to get away with simply using DNS if you have to.

I think you should be considering whether or not your NEC NEAX is able
to work with SIP signalling, which is probably the only way to do
this.

The cisco phone can take a SIP firmware load so you don't have to run
SCCP.  I've even seen them interfaced with an Avaya telephone system
using their SIP server solution, although in practice I haven't seen
any of the Avaya shops lining up to graft cisco phones onto their
systems.  

SIP would open your range of telephone devices to a broad range of
devices beyond the cisco phones.  It would keep you from getting
locked into any one provider.

Identify the protocols the NEAX can work with first, choose your
endpoint hardware second.

Thanks Ray and Tom,

I'm beginning to see it will looks something like this:
cisco 7960 phones > cisco call manager > SIP gateway > Neax 2000 ips

NEC has a product called Univerge that I think would be the sip gateway
portion.  I have about 200 cisco phones,  and I can see from the link
Ray gave that the intel machine does not support cisco.

The open source idea is interesting.  Somehow using Astricks as a
gateway might be possible-- though I'm too much of a newbie to know.

The only piece that must remain constant is the neax 2000 ips (it's
mandated).  This enables all of our offices to have nice 4 digit
dialing and queues.  However, if I can change the end piece to a cisco
7960 it will greatly save us time in wiring and allow people to move
freely-- just plug in the phone to a port.

Thanks for moving me forward in my thinking.  Be nice if I could find
someone else who has done exactly this :-)

Where did you see that Cisco phones are not supported?

I guess I misinterpreted this from the first page of the link to mean
Cisco was not supported.:

Handset compatibility
    Nortel
    Avaya
    NEC
    Siemens

I suppose handset in this case does not refer to ip phones?

Regardless, I still need to figure out how to take about 200 cisco IP
phones and get them to work with the Nec Neax 2000.  The SIP gatway
seems to be the way to go, unless someone can tell me differenet.
Otherwise we will just have to settle with what we have.  

Thanks.

Ok, that handset list is if you are using the model that can drive phones.
There is also a model of PIMG that can be used to help migrate away form a
TDM based PBX to an IP based one. This model lets you drive various digital
stations that you might have and still maintain an IP based PBX system on
the back end.

The emulating units (The MTL, RLM, DNI and LS models) will connect to the
PBX using a station port and drive an IPphone form there.

Tazzer, take a look at the network diagram examples at the website
that was suggested.

Buying the cisco call manager solution for your requirements is like
using a sledgehammer to drive in a thumbtack!

If you don't like what you see, you can still look at sip gateway
products from Nortel which should allow you to use the cisco phones
with a SIP firmware load.

Thanks guys,

As you may have guessed, I'm come into this sideways and am just
sorting things out.

I should have given the backstory to my question.

Our regional office had been running Cisco Call manager with Cisco
7960's for years.  Then our head office brought in the NEC NEAX 2000
IPS pbx with the digital handsets (dterm) and mothballed the cisco
equipment.  The goal was to have us all on the same equipment and allow
queueing, 4 digit dialing, etc between both offices.  The IP
connectivity is between the two offices.

The system is working well with the exception of how much work is
involved in maintaining staff moves and changes-- lots of rewiring and
manual maintaining of the handset port list.

This all happened before my time with the company.

Seeing as how we have the Cisco equipment already, I thought it would
be worth figuring out if we could get at least the phones to co-exist.
The re-wiring of extensions is fairly time consuming with the dterm
digital phones and it would be a huge win to not have to do that
anymore.

Thanks for your suggestions and patience-- At least I know this is
possible :-) .  Also thanks for the pointer to the network diagram.
