[cisco-voip] Calls dropping

[costas georgiou]

Hi All,
 
We have a CME gateway running at one of our sites.  Apparently calls have been dropping today.  I had a look at the logs and I could see the following:

I am quite sure this is a Carrier issue, I have raised it with them and they say the line is clean.  Anyone come across this befor?
