Call Park works on T22 but not a T42

[tbolick]

T22: version 7.73.0.50
T42: version 29.73.193.50

I have set up the line key for the T22 as Call Park : p-cid-XXXXXX
This does not have any of the choices for XSI or FAC or any other setup.
This works great, except it does not light up anything like I'd like.

The T42 however has the same setup, and fails. I can use Transfer with *70XXX to park to an extension, but I can't see any indication for it.

I'll probably end up using a different phone for rollout, but I am trying to get it working on what I have.
