I rebooted my SH which had R36 on it and it upgraded to R37. This then reproduced the issue on my SH as well. Interestingly, I have my own VOIP phone, a Gigaset DE900 IP Pro and this worked ok. So it looks like the Grandstream is not compatible.

Not to be beaten, I found a workaround and it now works ok. I bought a cheap router from PC World and hooked that up to the SH, but left the SH still in router mode. I then plugged the phone into the cheap router and it worked immediately. Why this works, I do not know, probably need a network guru to explain that one away.
