Just as a what if...
Lets say I have a 250 phone rollout. I have three incoming T1 lines (however thoes are usually setup) with say 1000 phone numbers available to me. Every phone is currently analog, but I would like to move to a VOIP based setup when the prices become comperable.
What am I looking at for equipment here? How do I possibly provide 250 phone ports with the Digium 4 port pci cards? Wouldn't I need a ton of them?
Thanks, Stan
Unless I read your question wrong, you want to ditch the analog phones and replace them with VoIP phones. Once you get the T1 Lines into the * server(s) with standard Digium hardware (TE410's), you needn't concern yourself with analog (FXS/FXO) any more. What you need is an Ethernet tree to distribute the voice packets from the * server(s) to the phones. There's lots of recommendations in the WIKI about ethernet switches (don't use hubs) and VoIP phone hardware. I also think there are several examples of people who have built * systems with that many phones and more. If you need a channel bank to hook up some analog phones, use one of the banks you probably already have for the existing T1 lines. Just run a T1 crossover cable from the bank to a spare port in one of the Digium cards.
