I had an identical problem with CM 3.09 and two 7940's. A PC could connect to the network fine using both data jacks, but any 7940 would continually reboot. It ended up being a cabling issue at the patch panel on the first and a cabling issue at both ends on the second.
Does the problem follow the phone or does it stay with the connection?
For what it's worth, I remember back when I assisted with a migration from a AS/400 CISC box to a RISC box, some of our existing cabling suddenly wasn't good enough any more . . . the RISC box amplified our problem runs (of which we weren't aware of up to that point).
In our testlab we had also some phones that were booting non-stop. The solution: the bandwidth to the phones was very limited (32 kbit/s) and the download of the new phone-image was terminated too soon. Using a better link (64 kbit/s) solved the problem.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
