We have 10 locations across 5 states on IPO 4.2.14 using an ASCN to connect: 8 406 controllers and 2 412 controllers with 1 VMPro 4.23 voicemail server. We have a fairly robust MPLS WAN, with at least 1 T1 in each location, and QoS is set up to prioritize voice traffic over data. Since March, we've had random alerts from the remote offices stating that the 'Voicemail Server is down', then three seconds later (literally)'Voicemail Server is operational.'
It is always the same amount of time, and there is no discernable pattern to the alerts. We've looked at all of out network monitoring tools and cannot figure out why this is happening. Any ideas / suggestions on how to track this down? It mostly happens after hours, but we have had a few during the day, and it breaks connections to voicemail when this happens.
