After converting to Unity Connection everything seemed fine. But now my users are reporting getting a busy signal some of the time when they hit the message button, and outside callers are sometimes getting a busy signal instead of a greeting when the call goes to voicemail. Any suggestions on where to look for problems?
Look at your Unity Connection integration with your phone system. If CallManager, are all of your ports registered? On Unity, how many of the ports are capable of answering calls? Your symptom sounds like all ports are in use. Look at Telephony Integrations in Cisco Unity Connection Administration. You can add and edit integrations there, as well as set port capabilities. A general rule of thumb is 75% of your ports should be configured to answer calls. Under Reports, I would run the Port Usage Report, which will tell you the number of ports in use by hour/day.
