<P><FONT SIZE=2>Hi<BR>
<BR>
Looking at using Asterisk for a new remote office with about 200 extensions. We have an existing EPABX in our central office with about 120 POTS lines.<BR>
<BR>
The central office and the new office will be connected over a 4Mbps leased line.<BR>
<BR>
We want to be able to connect our Asterisk box to our EPABX so that people with Asterisk VoIP extensions can dial out using the POTS line - and, of course, receive calls through the POTS line.<BR>
<BR>
I am informed that we will require a Digium card to connect the Asterisk box to the existing EPABX. This card, I am told is a PRI card that can handle 30 voice channels. This is fine. <BR>
<BR>
My question is - how many such cards can one Asterisk system handle? <BR>
<BR>
What if I want to enable three PRI lines on Asterisk? Is it recommended to put in three or four PRI cards in one Asterisk box?<BR>
<BR>
I have a dual Xeon 3.0Ghz (I think!) box with 2GB RAM - this box can be upgraded or changed as well and am running RHEL 4.0 AS on it.<BR>
<BR>
Thanks very much<BR>
<BR>
Best wishes<BR>
