<DIV dir=ltr><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><BR>Iyer</FONT> </DIV></DIV></BODY></HTML>
