Depends on the channel bank -- make sure it supports EM. If you don't need to support a lot of EM trunks you can take a look at Multi-Tech's VoIP gateways. Expensive but they support EM and ought to be able to be connected to Asterisk (although I haven't tried myself) using H.323 -- don't know about their SIP support. g. ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

A T1 card will. If the channel bank is populated with the right cards, it may be able to convert the analog version of signaling to the digital version. -- Steven Critchfield [EMAIL PROTECTED] ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

You typically do not need a channel bank when using EM. However, you will probably need a T1 crossover cable, if you are not connecting to the outside world (i.e. cross 12 with 45). -Tilghman ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

If the trunks are digital (a trunk per channel of a T1) then no channel bank is needed. Just plug the T1 into your Digium card and configure your zaptel.conf and zapata.conf files accordingly. If the trunks are analog, you would need a channel bank capable of converting EM trunks to a T1 and plugging this into your Digium card.

RE: [Asterisk-Users] EM Signalling
Thanks for all the replies. The system I may have to connect to has some spare analogue 2/4 wire EM trunks. I have two Multitech units but am having some difficulty with the H323 on asterisk at the moment. I think I have built everything OK but get problems starting asterisk with the h323 modules loaded. any help on the h323 would be appreciated as well.
