Hi, i’m Rosin Alberto from Italy. I'm apologize from my English.
I have a problem with Yeastar S20 IP PXB (firmware 18.104.22.168) and Fanvil X3G (firmware 2.3.1) phone.
Sometime, when we pick up the phone from an external call we can’t take the line, and the phone continue to ring. So, we need to put down and raise the handset again.
When a call arrive, the phone ring 3 times, little pause, other 3 times and so on. The problem that i've described seems to happen if we pick up the phone during the pause.
Have got any advice for me? Do you know about this problem?
