Hmm, I read a little more (checked the index) about Centrex and I found this as well: Centrex phone lines are POTS lines with special, business-releated calling features like four-digit private endpoint dialing. These are the lines on which you have to dial a 9 to get out. Centrex has the same economics of POTS - you generally pay a monthly fee that covers a certain amount of utilization on the line; after that, you pay by the minute. Centrex is less widely available than POTS. It's often absent from residential and rural areas. Like POTS, each Centrex line can support one phone call at a time. Seems the Centrex lines are exactly like regular POTS, you just get some added features. So I am not 100% sure how they have it worked out because I would think each POTS line which have a number (555-1111 and 555-1112 would be extenion 1111 and 1112 within the Centrex group). However, you say they have two lines but 5 extensions. The only thing I can think is they have two POTS which give them only two simultaneous calls at any given time, but have 5 telephone numbers assigned to this Centrex and just have the two Centrex lines in hunts group...but then again this would imply that if two extensions are talking directly to eachother, this would be utilizing the only two POTS available (since its Centrex and has to go all the way to the CO), leaving no available lines for incoming calls.....no? - Gabe _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
