[Asterisk-Users] GXP-2000 1.1.0.13 Issues

[drew-asterisk-users at elysium.ltd.uk]

I have had 2 GXP-2000 for a while now and been slowly following the 
firmware releases made by Grandstream and am now up to 1.1.0.13.  This 
version works really well on these 2 original phones (MAC's 
00:0B:82:06:xx:xx), so I went ahead and ordered another 2 phones (MAC's 
00:0B:82:09:xx:xx).  One of these I upgraded to 1.1.0.13 (it came with 
1.1.0.5) and pressed it into use.
The Speaker phone does not work at all (no sound from the Speaker) and the 
phone completely hangs doing a soft-reboot, other than that the phone 
seems to work well.
Unfortunatly I do not have a copy of 1.1.0.5 so cannot downgrade the 
phone.
Has anyone else noticed these problems, or does anyone have a copy of 
1.1.0.5.
