Definity and VoIP

[Boxer77]

I have a bit of a confusing situation that I need help with. We are currently running a Definity v11 with all analog and digital cards. It's at a large high school that is going through a complete renovation. It's pretty much a nightmare right now. At some point we are going to be getting a new system, but management doesn't feel the need to tell me when.

Here's two of my problems. Next month they are moving a whole bunch of offices to one side of the building. (Yes. They gave me 2 weeks notice.)The problem is that there is no open wiring on the blocks to handle the new phone lines. Running a 50-pair back to the phone closet which will be gone in less than a year is too expensive. The other problem is that the new student wing will only have data lines so we have to go VoIP when that opens in December.

My plan is to get a VoIP card installed and start migrating to a VoIP system now at least for the new offices and classrooms. How easy is this to do? The bulk of our network does not have PoE as of now but that can be fixed since we will have to put new switches in. Also, most of the phones are the 6400 series. Will those work with VoIP or do I need to purchase all new phones?

Thanks for your help.

believe me when I say that the 50 pair cable option is the easiest and least expensive option, as to go voip you have to purchase licenses from avaya, buy the poe switches, but the ip phones, as well as all of the programming involved.

Boxer,

It is hard to handle a budget or "wiring" issues on this forum. Do you have a Wire Vendor? I'm sure, if you do, they would be more than capable to remedy that issue.

Running VOIP phones without POE switches is a pain. You would need to outfit every phone with an individual In-Line Power Supply. If that can be solved internally, I would most definitely go the POE route.
To implement VOIP on V11 you would need the RTU’s so “ disp sys cust” at your term/ASA and make sure you have on page 2
display system-parameters customer-options Page 2 of 11
OPTIONAL FEATURES
IP PORT CAPACITIES USED
Maximum Administered H.323 Trunks: 12000 20
Maximum Concurrently Registered IP Stations: 18000 1139
You will need a Med-Pro, Clan, TFTP/HTTP server and corresponding DHCP Server with 176 scope options. I would have to refer you to either the IP Telephony Deployment Guide for proper setup.
You can run VOIP, Digital and Analog across the system with no issue. You can use your existing 6400’s where possible and implement 96xx phones where you can.

Hope this helps Boxer!

boxer77 as you can see from dtlegends post it would be tons more money to go the ip phone route, a 50 pair cable is the cheapest way to solve your problem.

You can not use the 6400 as IP phones. They would have to have the copper (not network copper) run back to a digital pack at the PBX. You would have to buy IP phones, like the 96x1 series, and ether PoE injectors or PoE network switches.

If cost is the main issue, run the 50 pair cable, and reuse your current 6400 sets.

Thanks for the advice. I will scrap the VoIP idea for now. At some point a new phone system is coming in so I am hoping it's before the new wing is opening.

A Definity V11 (CM 1) would not recognize 96x1 phones. Probably only 4606, 4612, 4624 and 4630 IP phones, which in itself would be an issue finding those older phones. Agreed, it would be cheaper to run the cable and use the existing digital sets.

My suggestion would be to purchase a S8300/G430 to install at the new location. It is IP Capable. Put a CLAN (TN799D) and MEDPRO (Refurb TN2302) in your existing system and put an IP trunk between the two. With a new S8300/G450 you can use any of the IP Phones and with the new licensing model you get the soft clients and point to point video. Best of both worlds and you can migrate when you are ready.
