BLF Keys - Watch a different extension

[Asanka]

Hi Guys,

We've a T46S. Just trying to see if this is possible (Asterisk Based).

I want to monitor *280. This is a day night toggle so that the person will be able to see if it's turned on or off.

However, if I press this button, I want the phone to dial *200 instead of the normal *280 above.

With Cisco this is achievable like this:

fnc=blf+sd+cp;sub=*280@$PROXY;ext=*200@$PROXY;
