I think the data may get to the zaptel driver on a native bridge. I'm not sure if there is a cross-connect in the actual TE405P card. However, barring missed interrupts there should be no frame slips and no signal degradation when passing a call from one T1 to another T1 on the same TE405P card. They all share the same clocking and there should be no slips, missing data etc. Peter _______________________________________________ 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
