I have a 3300 with NuPoint UM and had an issue develop a couple of months ago where voice mails, and at one point pre-recorded greetings, are choppy and will skip. The only thing that has changed on our network is a Sonicwall router was replaced (exact same one as was previously in place). Mitel is stating the issue is related to our network, but it appears to me it is an issue with the NuPoint server. There are no issues with live calls, only recorded messages and greetings.
An example of the problem, if you leave a message and count 1,2,3,4,5,6,7,8,9,10 what you may hear on playback is 1,2,4,5,6,8,10 or 1,2,3,3,4,5,6,5,6,8,9,10. Has anyone experienced a similar problem or does anyone have any suggestions?
