Headset Prior (Yealink T21P)

[dreemer]

Hello,

I'm having a huge issue at one of my offices; we have three Yealink T21P phones with Jabra headsets (these work great).

We purchased a Jabra remote handset lifter in order to be able to answer phone calls without having to push the "headset" button on the phone itself. I made sure to set "headset prior" to "true" in the web interface (of each phone); I can see that it's working because the icon changes from a phone to a headset on the phone's display (showing headset prior is active).

Everything is working, except when the lifter picks up the handset, it auto switches to the handset and you still have to push "headset" on the phone itself in order to talk via the headset (even if headset prior is active).

Am I doing something wrong? Can this issue be fixed?

Thank you in advance,
Ray.
