Do you other phone have the same issue?
Does your PBX enable call waiting?
I assigned Line 1 to all three of the line buttons and tested again, but to no avail, I'm afraid. So my only thought at this point would be to downgrade the dysfunctional phone to the same version of firmware that's working on the other T26P, unless you have any further suggestions, of course.
EDIT: I might also add that this wasn't necessary on the other T26P that has functioning call waiting as it stands now.

I definitely appreciate the suggestion, but they're basically both receptionists, which is why we got them the T26Ps (so that they can daisy-chain all the extra buttons, which our Cisco phones don't have the capability of doing). So it's a good thought, but I'm afraid it wouldn't really help in this case, as both phones need this feature working.
