I wanted to see if anyone who has recently completed a VoIP implementation on their campus has  a VoIP implementation / Project plan they are willing to share?  It is always best to learn from others experiences to avoid issues we may not have considered.

 

You are welcome to contact me off list.


Thank you

Not sure if you'll find this helpful but I'll blab on some of our current thinking and plans ...... We are currently at a 50 phone pilot phase on a VOIP system; about ready to expand to 100 phones with the completion of a new building project in December. We even "tested" (not by choice) a condition in which our core switch was at 100% CPU and the QOS on the switches seemed to keep voice quality good. We have prepared the network infrastructure over several years for a time such as this. As part of a normal replacement cycle, we have transitioned all (ok, almost all) of our edge switches to POE and have made sure they pay attention to priority information in tagged packets. For most end users, the phone will plug into the switch port and their desktop/laptop wired connection plugs into the phone. That reduces the need to greatly expand switch port capacity. The phones can generally tag vlan and priority for their own traffic while leaving user data traffic as-is. Another fun thing to plan with -- Wifi based wireless phones. We have not planned how they fit into our mix yet. Depending on budget factors in the next few years we have tentatively laid out a 4/5 year plan to migrate generally by building (by office in the building) from our current Siemens Hicom system. Overall, we will end up with about 1100 phones. We plan to leave all outside lines flow through the Siemen's system until about 3/4 of the way through. In our case, there are some known convenience issues during the transition mainly related to caller id. Our Siemens switch absolutely will not send internal caller id information to an "outside" system (anything other than Siemens stuff). Calls from Siemens to IP lose caller id. The other direction is just fine. We have based our current implementation on the sipfoundry open source platform (www.sipfoundry.org) with success. The sponsoring company, eZuce has a special EDU program (currently being revised) that will allow us to obtain their commercial version and support with a huge savings on license costs (like $250,000 savings in our case) vs a more common commercial system like ShoreTel, Mitel, Cisco, etc. Is it perhaps more risky than the big names? -- yes. But then again we are using Polycom phones which can operate on other open source platforms and some commercial ones. Considering that the phones themselves are a huge part of the system cost, ones that can operate with more than one vendor are appealing. Another huge cost are the traditional license costs which we hoping to avoid. As we expand, our plans will remain under constant evaluation. I'd be happy to talk about how the two systems communicate and how calls are routed between them if anybody wants to hear that level of detail. I have not seen much response on this thread but I know a number of institutions that are further ahead than us. If any of you see this and think, wow are they being stupid (or any other thoughts), chime in. Tony Wyland Director of Network Services Messiah College wyland@messiah.edu 717-766-2511 x2380
