Can only use 4 BLFList Keys with Broadsoft

[AGingerich]

We've been evaluating the T26P and T28P phones for deployment to potential Broadsoft/Broadworks customers.

Largely, it has been a pretty good process... however, I've run into a peculiar problem.

When using the BLFList, the T26P does not correctly work with more than 4 BLFList entries configured in broadsoft. If I put 1-4 entries in, it seems to work correctly.

However, when I add a 5th entry, all of the lamp buttons turn off, and remain off until I delete the 5th entry.

I was originally using 6.61.0.83.rom, but upgraded one phone to 6.70.0.130.rom, and it did not fix the problem. We have a customer who would like to use this feature on the T26P today, but it so far is severely limited by the arbitrary 4-entry limit.
