Hi,

I work with Bill. Here is a review of what has been done so far.

New 509 Processor, 308EC, (2) 400 and large pc mail card installed. Installed 6 18-Button Display phones and the customer used 9 plantronics T10 analog headsets for their telemarketers.

After installation, system would crash. Log shows "software initiated cold start".

We started by adding a UPS to the system. No change.

Swapped out 509 Processor. No change.
Swapped out 5-slot carrier. No change.
Swapped out 308 expansion. No change.
Swapped out 400 mods. No change.

Found 2 pairs reverse on cable for Ext. 10. Corrected and system stayed up for 2 days without crashing. Then crashed.

Have checked all other cabling. Have removed groups of the analog headsets. System continues to crash.

We are taking each CO line out of the system one at a time to see if that could be the cause.

Have not swapped out VM card yet.

We are currently trying a new 18-button phone at ext. 10 and will rotate it through the other locations as the system crashes.

Any other suggestions?
