vvx Line key serve as Prepend

Hi All.

This is the Phone Information

Phone Model VVX 300     

UC Software Version

Updater Version



I want a line key to serve as a Prepend.

Not a soft key but a line key, the keys on the side of the screen.


So when dialing a specific Line key for example line key 4, the phone should prepend *952 before the destination phone number.


Can someone give me the code to upload to the phone to have this done.


Thank you all.

Hello @Jack Noe,


welcome to the Polycom Community.


I do not believe the exact scenario is possible as an EFK action would probably only send the stored digits. You could look at a prompt or the Digitmap.

I think we currently have an enhancement ENH-1262 for this but you would need a Polycom Sales Engineer to add your opportunity to this.
