I have a band new Avaya Parnter ACS R6 with Partner VMS R6, and 34D keysets, and on a Verizon CO in California. Very intermittently, when a call comes in and gets routed through the VM, exactly 5 seconds after a user answers it, it gets dropped. At that exact instance, the user who answered the inbound call hears a two-tone signal, similar to a french police siren (the outside caller hears nothing, however, just a dead line.) It's the same tone that you get if you leave a Partner line or intercom engaged and unattended for a minute or so. The tone is not coming from the CO, it's definately from the Partner, since you can generate same tone even if you are not connected to the CO (again, by leaving a line or intercom engaged and unattended).

The drop happens about every 10 or 20 incoming calls. It can happen on any line, any extension, and while any number of people are using the system. One interesting point... it always happens 5 seconds after a user answers an incoming call, NO MATTER how long the caller had been listening to a prompt before choosing an extension. And, amazingly enough, if a call is connected normally (not dropped), but the user puts the call on hold, then when the call is returned to it can still happen, again, exactly 5 seconds after returning to the call. And it's ONLY on incoming calls.

The local vendor has double checked the wiring and programming, and we've had the lines tested and re-tested by Verizon. Any help appreciated.
