Hmm. Maybe the dinosaur would make a nice answering machine. > I wouldn't try running a PRI card in one.

I've got a 266 Celeron in a laptop running W-me. Not much of powerhouse, that one. It was better when running Linux.

That makes me recall some things I read in the archives about DSPs on boards vs not on boards. > > > POTS phone-----[ * ]---PRI---[ * ]---POTS phone > > > > I assume that I'll need to get a couple line cards and a couple T1 > > cards. > > a couple of FXS cards and a couple of routers to handle a data T1/PRI. line side? generates ringing? http://www.marko.net/asterisk/archives/0001/0098.html Instead of routers I was thinking of using a twist cable with RJ45 on each end: 1 RT - TT 4 2 RR - TR 5 4 TT - RT 1 5 TR - RR 2 The PRI link is only one meter in a captive environment. Based on everything written so far, I think I'll build a couple of low-end machines sooner rather than later. -- Mike M. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
