Cheap and Reliable IP Telephony?
anomalie asks: "I am trying to sell IP telephony to my employer. The idea was shot down once already because of the cost (using a Cisco solution). I would like to find a cheap but reliable IP PBX because everyone liked the idea of IP telephony, just not the price associated with it. I need a system that could initially handle about 80 users at a single location, and eventually handle about 350 users at 7 locations. The two systems I have been looked at so far are Asterisk & Pingtel's SIPxchange IP PBX. I'm not looking here for a final solution, just some starting points for more research. Any feedback/tips/warnings from the Slashdot community?"
"I am looking to have at least the following capabilities:
-Auto attendant
-Handle a PRI (hopefully allow forwarding of old PBX DIDs)
-Handle long distance T1 (we would initially segment off some channels from our current PBX)
-Handle WAN Traffic so we could utilize our unused channels for long distance from other locations
-Forwarding of voicemails to email
Nice optional features:
-Web based GUI for voicemail administration
-GUI call manager
Eventually, we would have relay units at the other locations to handle the local calls and call routing and have 1 central PBX at corporate headquarters."

It seems like replacing your current phone system is going to cost more in the short term than just sticking with what works. Will the IP telephone system cost less in the long run? What is the time frame to break-even? Will your company still be around by that time?
I have been pwned because my
The only corporations that would actually stand for a gain from the benefits of IP phones are the ones that would not balk at the price of the hardware.
The largest sum of money spent on phone systems is usually interoffice calls. Why would you set up IP phones in a single location as your goal, then add more offices as a secondary "good to have?"
This is not sound economics -- just because speaking over your cat5 network is cool does not make it a smart thing to do.
