Thanks for your input!

Previously I was using Nortel 10/100 switches, I replaced them some 
weeks ago with 3C16479 gbit switches. The phones are connected directly to 
the gbit switches. By coincidence I dit notice on one phone that in a 
split second a message appeared 'Ethernet cable disconnected'. Because I 
have cable unplug set to ignore the conversation was not interrupted and 
the conversation could continue.

But that still doesn't solve the occasional lockup.

One phone was giving me *lots* more reboots than others but that was due 
to it running firmware 6.0.4 without having the ramdisk converted to jffs. 
Apparently the firmware didn't like that at all or just runs out of 
memory and decides to reboot.
