The customer just switched dialtone providers on Thursday. We will see what happens next.

I have also placed another 509 processor in the same phone closet connected to nothing but the power supply. It has cold started once vs. multiple times for the entire system.

Other ideas that have been floated:

The system has the Avaya Large PC Mail card. This company runs a lot of help wanted ads and gets flooded with calls. Is it likely that the system gets overloaded with all of the calls trying to get through the 2 ports on the PC card? I would have thought it would just be "ring no answer" until a port frees up.

Another theory is that the telemarkets using the analog headsets get their line access via a pool. Extensions 14 & 15 (18-d's) have access to these lines on their phones and select lines by pushing a button. Is it possible that there is some sort of collission confusing the system if someone in telemarketing is trying to get the same line at the same time. Seems unlikely to me, but throwing it out there.
