We have fairly a larger deployment, over 1000 end points of CX 600 and few numbers of CX3000. Recent order of CX3000 and CX600 came with the firmware CU7 (4372).
None of the devices are getting registered to the Lync (2010). It gives error saying user name and domain is in correct. Whereas in the error, domain is replaced by the username. If an incorrect password is entered purposefully it gives an error saying the invalided password, and the error is displayed with the correct text. This is check with USB plugged in.
Any advice is highly appreciated.
