Expansion Module Keys

I'm attempting to provisiong a Polycom 650 with a backlit expansion module.  The phone is running UC 3.3.3 and we have a Metaswitch provisioning system.


The issue I'm experiencing is that I can't seem to correctly set the attendant keys.  I spoke with our Metaswitch contact and he explained that the keys must be set sequentially.  Unfortunately, our customers can be quite picky and we field many requests asking for certain functions to be placed on certain keys.


My question is, is there any way to put a "placeholder" on a key in such a way that the phone will view the key as programmed?  Does Polycom recommend any methods that could be more efficient?


Thank you,

Re: Expansion Module Keys

Hello Charles,


welcome to the Polycom Community.


You should check out the new UCS 4.0.0 which added the following:


Example Flexible Line Key Assignment Configuration

To enable flexible line key assignment, in the features.cfg template, set the lineKey.reassignment.enabled parameter to 1. Then assign each line key a category and an index. The category specifies the function of the line key and can include: Unassigned, Line, BLF, SpeedDial, and Presence.

Note that the category Unassigned will leave that line key blank. The index specifies the order in which the line keys will display on the phone screen. Use Table 6-20: Assigning Flexible Line Keys to help you assign a category and an index to the line keys on your phone.
