Centrex in its most common form is physically the same as a loop start POTS line. If you can plug a plain old phone into it, get dial tone, and make and receive calls an FXO card will work. You'll need to set the dialplan to input a leading 9 to call out to the PSTN from the Centrex line, and you can also build a dialplan to call other Centrex stations of the business with typically three or four digits. Generally these inter-office calls are free of message unit charges. If a regular phone rings but the Asterisk doesn't detect ringing, try swapping the two wires of the line, also make sure that the Asterisk has a good ground. Some ringing circuits are fussy that way. -- Jay Hennigan - CCIE #7880 - Network Administration - [EMAIL PROTECTED] WestNet: Connecting you to the planet. 805 884-6323 WB6RDV NetLojix Communications, Inc. - http://www.netlojix.com/ _______________________________________________ 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
