Cost and ease of deployment, yes. At this specifc location we are currently using Centrex lines (AT&T hosted) and are looking for a way to move into something cheaper without throwing away the existing phones. I like the idea of using a channel bank - I'll look into that as an option as well.

I'd like to get this done cheaply, but I want to make sure that whatever we buy works well with asterisk as well. As far as I can tell, digium make no such device. The only ones I've been able to find with a 48 port capacity are these two: I have a deployment of 96 analog ports using a Digium T1 card ($500 on eBay) and Rhino analog channel banks (also cheap on eBay). We have extremely high reliability from this configuration. In fact, other than the normal analog annoyances like occasional echo, they are rock solid. Are you doing this instead of VoIP phones for cost reasons? -- Carlos Alvarez TelEvolve 602-889-3003
