When I responded to Eric's original post, it sounded like he was trying to interface to an older pbx trunk interface (physical interface). Those physical E&M interfaces were as described above (each had either four or six wires). What the original post didn't say was the interface to the non-asterisk pbx was a T1, and one (or more) of the channels were configured for E&M signaling. Completely different then a physical E&M interface. (Someone else had asked about a physical interface not more then a couple of weeks ago, so the mind was oriented along those lines.) _______________________________________________ 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
