We upgraded our IP Office system to the latest firmware about 3 months ago. We continue to have issues with the system, post-upgrade.
Issue #1
Primarily, our CID does not display correctly anymore. We now see "External" about 50% of the time on incoming calls. This started happening the morning after our upgrade to 4.12.
Issue #2
We randomly get an Error "8kHz clock source changed. Previous source was internal".

Aside from these issues, I do have a few questions as well:
In the call monitor software we can look at line utilization, active calls, etc... It appears as though incoming calls are placed on channels 1-12 and outgoing calls are put on channels 13 - 23. If all channels of the PRI are in use, what happens to incoming calls? Is there a way to prioritize calls so that INCOMING calls get priority over outgoing calls? We are looking to install another PRI and have 2 total with 46 channels available. Our Control Unit Module shows Port A and Port B (port A has a T1 and Port B is empty). Can Port B be equipped with another T1 module to handle the 2nd PRI or would we be forced to get a totally different Control Unit?
Thanks so much for your time and love the fact that this forum is available for the end user. Our Avaya support "team" is not always responsive and most of the time has very ambiguous answers that appear to indicate they themselves do not really know the answers either
