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

Since your setting up that many in my view you will need more then one asterisk server and use TE410p board which give you 4 T1 connections each. So do the math and you can figure out your setup.> Thanks, > Stan > _______________________________________________ > Asterisk-Users mailing list > Asterisk-Users@lists.digium.com > http://lists.digium.com/mailman/listinfo/asterisk-users > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users

Take for instance the fact that an ADIT 600 can take 2 T1 lines and turn it into 48 analog phone lines. So 3 ports for your inbound T1s, and 11 ports to cover the analog ports. So 14 ports divided by 4 and rounded up to the next highest integer and you have 4 four port cards. -- Steven Critchfield <critch@basesys.com>
You can purchase multi FXS channel banks. Check them out at ATACOMM.com they sell them there. You will be able to get the 250 analog ports you need from that. .o-------------------------------------------------------o. Brian Fertig Network Engineer Planet Telecom, Inc.

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. Stephen R. Besch
