I am fairly new to the world of phone systems, and am working with a Nortel system for the first time. I have run into a problem with a Compact ICS 4.0 with M7310 telephones. While changing telephone numbers for line 3 I lost the audible ring on line 3 only. Line 3 was ringing fine with the old #, But with the new # I have no audible ring. I have dial tone and can call in and out. The arrow flashes for line 3 when a call is coming in, but no audible ring. I first thought it was a blown fuse. Since this is the first time I dealt with a Nortel system I can't find any changeable fuses for this system. Does it have fuses and where are they located? I'm not if this is a programming issue or a problem with the system it's self. I feel like there is a simple solution, but since I have very limited time in this field, I'm stumped. If anyone can point me in the right direction I would greatly appreciate it.
