Intermittantly - extensions don't ring

[brianoakes]

Unfortunately this problem is intermittent, so I need some ideas of where to start looking. I have seen the problem occur a stock template as well as our custom one.

v15.5.13103.5
Polycom FW 4.0.11 Models 335/550/650

What we are seeing is random and pretty intermit. A call will not ring in at an extension. It will ring directly to voicemail, or in some cases ring once then goto voice mail. It has happened in a DID call and an internal transfer. The caller is hearing the rings, but on the physical handset, we see 0 missed calls or after the 1 ring and goto VM, we see a missed call on the display.

We didn't notice it until about 2 months ago. It was around 15.3 at that time I think, but not sure. We have sense upgraded to current just to make sure.

Any ideas/suggestions on where to start looking/logging?

It would appear that the set is not seen as registered (or is busy)at the time the cal comes in. You should be able to confirm this in the 3CX Activity Log for one of the calls. You'd then have to determine why the set is not registered, perhaps it is not re-registering in a timely manner.
