I've got one that's kicking my butt-- hopefully you smart guys can help. [Linked Image from sundance-communications.com]

I have a G1632 Comdial DSU (v 20A) with a Key Voice Corp Office Dos (v 8.2) with Rhetorex boards. The system will not reliably dial all digits of a phone number (usually a cell phone) when notifying of messages in the voicemail box. I figured that out by monitoring a SMDR port and noticing that all of the digits are not dialed. Also, random internal extensions are dialed when the failure occurs.

Any ideas? This system used to work ok, but now doesn't. I tried reloading an old COS setup into the DSU, and have tried several other vmail PC's and Rhetorex boards to no avail...

Thanks for any help!
