Hi There,
We've recently had our Mitel tech's link up our 5000 to our 3300 via SIP. The connection joining the two systems is a 1.5meg DSL connection over a private mpls.
The issue we are having is periodically throughout the day if you try and call between the two systems in either direction you get a destination unreachable error on your phone and then your phone reboots.
This happens on either side. The connection between the sites is fine during this period.
Any ideas? Also reports of terrible call quality between sites. ATM the only data passing over this link is voice traffic, and a single call at a time...
