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.

Did you ever get and answer to this problem? I'm experiencing the same problem.

Can either of you narrow this down some? Does it always happen only on 1 set, or 6 sets, or 8 sets? Does it always happen on 1 line, or 2 or 3 particular lines?

Have any components been replaced by your vendor - processor, expansion modules, remote access/backup restore card, etc.?

After further testing we have been able to make it fail on ext 23 & 24 (only) analog station lines locally. These lines were originally connected to an opx line without an oprse. Since then we have purchased an oprse as required. The disconnect is very Intermittent. Question could we have burnt ports 23 & 24 without an oprse.

Wait - these 2 extensions are on the far end of an OPX circuit? Now it makes a lot more sense about dropping 5 seconds after connecting to the phones, regardless of how long the caller was in voicemail. I would first try changing them to different ports if you have enough free ones since that is extrememly easy and will eliminate the ports as the problem. If the problem continues, connect a trunk line directly through the opx circuit and try to replicate the problem. If you still get the problem with a CO trunk connected through the OPX circuit to your analog phones, talk to your carrier the problem is with the opx circuit itself (or the wiring associated with it - check for loose wires at the cross connect fields).

PS Just for hoots you might consider bringing a spare analog set with you (bring one from home if you have to) when you do your testing with the CO trunk.
