I have the exact same problem with my Grandstream phones (Snom's are 
fine) and others have reported it as well with GS phones but this is the 
first time I have heard of this problem in X-Lite..

All I can suggest is that you use the latest version of x-lite and see 
if it helps, other than that I have not been able to find the answer..

Good luck, and if you find a solution let us know..

Later..
