Gabe,

My Linksys phones do seem to reboot every time they sync the config. 
However, I have the Message_Waiting option turned off. Is there another 
option that you think might be related to the rebooting? I do not think it 
is a DHCP issue because the phones get the same IP address each time they 
request one from the DHCP server. I am using the 5.1.8 firmware, which I 
believe is the latest for the 921 and 941 phones.

I have put one of my configuration files online here:
http://209.190.22.48/fs/linksys/

I changed a few things like username/password/proxy/provisioning URL, but 
otherwise left everything the same as one of my real configuration files.

Do you have a sample config you could send to me for a Linksys 901, 921, 
or 941? I would love to be able to compare to see what other options might 
make a difference.

Regards,
Wellie
