Hi

I have purchased a Yealink T20P phone and have configured it to work on the 2Talk service. I can make calls without any problem. However, for an incoming call, when I pick up the handset to receive the call it does not answer it and the caller gets a continued ring tone. When I pick up the handset, my phone stops ringing as if it has answered. This is the same whether I use the handset or the speaker phone button.

 

Any ideas about why this might be happening and how I can resolve it?

Thanks
