For internal calls (at least, not sure about external), the number of rings the calling party hears before Unity voice mail answers is sometimes 8 to 10 rings. Usually it is only 4 rings and the RNA timers, etc. are configured to support 4 rings. The Unified Communications Manager Express version is System version: 220.127.116.1100-2. The Unity version is Version 18.104.22.16800-18 Why would it sometimes go to so many rings? How would I trace or troubleshoot these versions (on locked down Linux appliance) of the systems to know if the problem is not enough available voice mail ports at the time I see the increased number of rings? Thank you.
Yes, you're right. Thank you. I downloaded and installed the Port Usage Analyzer for Connection tool, version 7.0.12. I can run it, but fro some strange reason it will only let me select the most recent day of 5/24/2011 (today is 7/11/2011) to load data from. Why won't it let me select a more recent date? is there some database configuration I need to check/change?
I have the answer on this issue & would like to share it with all of you. The problem with Unity being slow to answer was caused by the configuration of the Call Routing Line Group for the Unity ports in the CUCM Admin page. The distribution algorithm for that line group was set to 'Longest Idle Time’. It should have been set to 'Top Down' I speculate the original setting was causing it to consider Unity ports that are not set up to answer calls when it should not have been doing so.
