The only person in our org that knew the phone system is unavailable for the time being, and my understanding is we don't have a support contract with our vendor any more--they came out so rarely that it wasn't cost-effective.
So now we're stuck with a problem that none of us can figure out.
An analog phone recently started reporting that the line was busy, even when the phone was hung up, sending the caller to voice mail. One ring, then the busy message. Outgoing calls still work, voice mail works. Resetting the extension didn't help, and someone compared every setting, line by line, with her own extension and they were all identical.
On the hardware end, I tried three different analog phones and even reterminated the cable, but there was no effect (no change when I tried even with the cable unterminated). I tried some of the default feature codes (to turn off busy forwarding, for example), but the phone immediately went to the invalid number tone when I hit *.
Our technical level on the Mitel is very low, so we're not going to be able to do anything remotely complicated to troubleshoot or fix, but if I could get some tips on where to look or a setting to change and avoid a out-of-contract service call, we'd greatly appreciate it.
