Enable Forwarding through Action URI?

[Rayfield]

I have customers who have T28P's with 3CX PBX's. I need to be able to allow these customers to easily use No-Answer Call Forwarding. Specifically, they need to be able to easily enter the number to which the phone should forward when enabling No-Answer Call Forwarding. So far, I have found no easy way to do this in 3CX. Of course, it can be done in the T28P through the Menu on the phone, but that's not very 'easy' for some users to do.

Some older documentation that I have indicates that this can be set on T3X phones through an Action URI. I tried this on my T28P and it did not work, but I may not have the correct 'syntax' for doing this on a T28P.

Can this be done on a T28P and if so, what is the correct syntax for the URL to send to the phone?
