Hello I have a grand stream as a sip extension of a Toshiba IP Edge and I am tying to get the programmable keys to work in a similar fashion to your DSS keys on your Toshiba light up when an extension is busy ring the extension Under the programmable keys I have line keys as well as soft keys under the line key there is something about BLF does not seem to work and not much under the soft keys? I see the GXP2140 can get a extra panel 20 keys and they are called multi purpose keys. Do not want to buy panel unless I am sure it will work a DSS keys
Lastly would also be nice to be able to program a one touch(Toshiba)on the grand stream. Has any one had any experience with the grand stream and the IP Edge and any more tips would be welcome much appreciated
