I missed the part about Xorcom initially and I see nobody answered it yet. Yes, a Xorcom PRI module should be able to take fit here and get timing from the main Zaptel / DAHDI timing source on the system. IIRC, though (some? all?) Digium digital cards have a sync cable option which may be what you need here. -- Tzafrir Cohen icq#16849755 jabber:tzafrir.co...@xorcom.com +972-50-7952406 mailto:tzafrir.co...@xorcom.com http://www.xorcom.com iax:gu...@local.xorcom.com/tzafrir _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
