Grandstream GXP-2000 Enterprise IP Telephone

I said I would post again should I find any problems... well;

In GSM mode the phone is reliably unreliable - it seems to freeze randomly during a call [sits and repeats the last 0.1second of audio before the crash].. the only way to recover is pull the power out and put it back in.

It could just be network conditions as my ADSL line is well overused.. but I suspect its a bug with the GSM implementation on the phone and the silence suppression built into the codec?

Using it in PCM mode is perfect - no complaints otherwise!
