I have a customer with a Nortel CICS and when he is on line 1 and 2 and line 3 rings...he hears 1.5 rings and then the calls goes somewhere and he's not sure where the calls is ending up. He does not end up getting a voice mail so he believes the call is being dropped. Any ideas?

Two things to consider:

1. Call forwarding on CO line #3 from the telco. Try dialing *73 from this line to cancel it. A half-ring reminder that CO call forwarding is turned on could be causing the system to start a normal ring cycle. This sometimes happens when telco voice mail used to be installed on the lines but has been discontinued. The mailbox is gone, but the forwarding isn't removed by the telco.

2. Ring Trip: The CO line could have enough of a fault on the ring side to cause calls hitting it to ground out and cause the CO to think it's been answered. Is there humming noise on the line (3)? Are you able to call the number associated with line 3 and get through?

Both of these are likely telco issues, but you have to cover all of your bases. If these aren't the solution, then it's an issue with system programming or hardware that will likely require the services of a technician who knows that system inside and out. I figure that you'll see replies from people with more knowledge about this system shortly.

Hi eastcoast,

When line three stops ringing, does the indicator light solid, or does it go out?

If the indicator is lit, push the button. The system will tell you which extension has answered the call. This could help your troubleshooting if it is a system problem.

Good Luck!
