Flashing BLF for on-hold / on-park calls

[bcytepg]

Using QX50 with 8 Polycom VVX 450 phones.

Can I adjust the BLF to "flash" or change color while calls are on-hold or parked? As of now, they can only be solid red while calls are active / on-hold / parked. I don't know if this is a Polycom setting or something that can be controlled from the QX50.

Hello,

The BLF color change and flashing attributes are the behaviors controlled by that phone depending on its model. The QXs have no control over them.
