All of the sudden my analog night service extension stop ringing, but i can answere the phones and have dial tone and can make calls outside and internally and when dialing 0 at the console which is a brown colored one old style it does ring at the console , the problem is that the incomming ringer wont ring on that extension but can answer if i pickup the phone checked the ringer on the phone all good also cancelled all call forwarding option.
what could be wrong could it be the card or some programming issue? my system is SX-200 216G -03
