Cheers...
We seem to be experiencing problems with phones (so far only Grandstream 
GXP2000s) falling off the list of registered SIP clients.
I'm presuming that this is because they're failing to re-register within 
the previously agreed registration lifetime.
Any tips on debugging this would be useful, but I'm going to start by 
setting a very short timeout on the phone and watching to see what 
happens on the server.
