    Hi,
    I'm using latest version of 3cxphone for windows (12.0.37098.0 on Win 8.1 in 3cx mode) and latest firmware of Yealink T20 ( 9.72.0.80) and only thing I can get with it is quick flash of both links on Yealink and that's all, no missed call, no ringing. I can call from Yealink to my 3cxphone rings but quality of call is so so.
    But when I use older version of 3xcphone (6.0.19548.0) everything works.

    Any suggestions?

    Thanks
    DoubleB

    Hi there,
    Please always stick to latest supported firmware for your handsets, you can get this info through Phones page / Upgrade firmware button, in your case for T20 fw should be 9.71.1.1, not higher so please downgrade and see if issues persists.
