Hi Rich, good advice about buying grandstream SIP handsets instead of using analog handsets though I think you might that using a 30 channel E1 in Hungary is tough to get.
Can you also explain to him about Channel Banks.

That would be one way to do it, but I don't think you'll find many PC's that will have 7 slots for those cards. You might consider using 20 SIP phones instead of the analog phones. Twenty Grandstream phones would cost about $1500 (US) while five of the TDM fxs cards would cost about $2000 (US). Another way would be to purchase a Digium T1/E1 card and a Channel Bank. A channel bank with fxs cards will handle 24 analog phones, and would connect to asterisk via a T1/E1 cable. > Can I use these card in one PC ?, or I need more PC s ?

I would not suggest running any more then two TDM cards in a single PC as you're likely to have interrupt/bus problems. > Iam from Hungary , where can I purchase cards ?

Lots of good information and some references to where to purchase stuff. _______________________________________________ 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 _______________________________________________ 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
