I have two phone the 3CX client and a Yealink T22P. The T22P can call the softphone no problem. When I call the hard Yealink from the soft phone the Yealink t-22p Beeps once the screen lights up as if it missed a call. in the call logs it shows a call from (005) to (006) was made and Not answered. I have rebooted both phones and the same thing occurs. I am not sure what might be the issue.
