That generally means that there is a problem with the Codecs you are trying to use.

It means that this device is not completely compliant to RFC3264
3CX Phone offers audio and video media (video media can be disabled in phone configuration).
In any case, device should not reject offer completely, it should simply reject video media and continue with audio.
