[Asterisk-Users] Hardware for PBX with 4 incoming/outgoing lines and 20 phones

[Andrew Elchuk]

With this solution, I could have a Wildcard TDM400P with 1 to 2 FXO 
modules on it to handle 1 or 2 incoming calls on our current lines (I 
would get rid of 2 lines).  I would then use a T100P connected to a FXS 
channel bank with 20 phones or so.  Then for any outgoing calls instead 
of going out on an FXO card, I could just get a VOIP account at a place 
like iConnectHere and use that for any outgoing calls we make.  I 
believe that would save a lot of money as we do a lot of dialing out and 
long distance isn't cheap.  Is there a specific VOIP provider any of you 
have experience with or would reccomment, iConnectHere seems not to bad 
from what I've read.  And are there any channel banks that you guys have 
experience with or think would be good for what we want, I've read about 
the Rhino Channel Bank and it seems like it could be used?  Thanks everyone!
