Solved Registering/Provisioning Yealink W60B wireless ip phone

[CXteleco]

Hello,
I just can`t register an extension in my Yealink W60B ip phone (firmware version 77.83.0.25 ).
Provisioning doesn`t work. I can't see anything about its registration in the activity log of my pbx. Is any special procedure to register this kind of Yealink Phone? It worked fine with my old pbx for year.
I've tryed this:

Yealink phone shows Register Error.

Any help is welcome.

Check if IP address of W60B is not blacklisted.
Reset the W60B to factory default, re-provisioning it and try again.

Thanks complex1, you were right, it was blacklisted due to initials tests. Thank you very much.
