Hi i'm having problems with our phone system where by calls are being dropped intermittently. The call quality seems slightly degraded also?
On looking at the error logs i can see every now and then it has a major alarm then a few seconds later will go back to showing no alarm and all fine. Some of the diag logs since a full reboot are shown below - I notice D-Channel keeps reporting going UP and Down.
I've reported to BT who have checked the line and referred it back to a Mitel local phone system issue. I know they pretty much always say this! Hopefully the errors below will indicate where the problem lies?
Thanks in advance
