Using IP500s (4.2 and 5.0), SCN, centralized VM (4.2), and CCC 5.0.68. CCC is running at the central site (with VM Pro) and one other site (out of 6 total sites in the SCN.) Both the CCC sites are 4.2. The two sites with CCC use a projected PC wallboard to display the number of calls queuing and the longest waiting caller for the local call center.
Recently, the PC wallboard display at the remote site stopped displaying an accurate count (the central site is still working correctly.) The displayed count is generally zero. Something changed, but so far we can't find the problem.
This has occasionally happened before, and bouncing the Delta Server, rebooting CCC, etc. would clear the problem. But not this time.
The best clue we have is related to queue announcements. The call center hunt group (and the target for the PC wallboard) has announcements enabled (first at 10 seconds, second announcement at 30, repeat at 45, no synchronized calls.) The PC wallboard correctly displays the queue count until the first announcement starts (i.e. for 10 seconds.) When the announcement starts, the PC wallboard queue count goes back to zero and doesn't recover. We increased the first announcement delay time to 30 seconds, and, for 30 seconds the PC wallboard display is accurate. We also turned off queue announcements completely (for testing), and, the PC wallboard works perfectly.
The remote site has no apparent problems communicating with centralized VM Pro (auto attendants, voice mail, queue announcements, etc.) We use standard queued and still queued start points.
The PC wallboard used to work at the remote site. Networking obviously is a point of interest, but we can't find any recent change, and, all other Avaya traffic between the central site and remote site is working normally.
Any ideas?
