The InterTel Axxess had a good solution to this. Each station card had it's own ringing generator which produced ringing voltage at about 70 volts. It worked for most things but we had problems with a few modems and double-gong ringers. If you needed more, you would move a jumper on the card which would disable the internal generator. Then, you would provide 90/20 on the 25th pair of the AMP connector. In my mind, I imagine something very similar. It would look like an old SCSI card from the back of the PC with the big 25 pair connector. Pairs 1-24 would be the station lines and pair 25 would be for the external ring generator. --Shane _______________________________________________ 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
