Customer complaint - Intermittent issue (roughly 5 times a week). I have not been able to duplicate it yet. All calls are answered by the receptionist. She is telling me that when she does a direct transfer to ext. 402's (for example) mailbox that the caller will get ext.436's mailbox. The customer zero's out back to her and they say "I asked for Joe Smith and the mailbox greeting said it was Suzy Que".
Also, there have been complaints that when internal extensions call other internal extensions that intermittently they will get the wrong person. "I dialed 410 and Joe at 428 answered at his desk.

Work completed so far:
-replaced the back plane of main cabinet
-check all extension feature keys
-called many,many times to try to duplicate to no avail.
-checked that all VM ports answer individually and I can transfer to each.
-ran a maintenance check/test on the KSU through programming. All came back okay.
-watched the receptionist to be sure she is transferring correctly.

My hunch is that there are DTMF's being confused in translation by the system. I'm not sure how to check this though on a Tadiran ICE. Technical support has been no help other than to say that it should not be doing that.

Phone System issue or Voice Mail issue?
What can I check for?

Thanks!
