Re: Urgent! IP Phone every day needs to plug in the netwowk

Muhammad,
                    Replace the patch cable from the 7975 to the Switch with a
Factory made (Cat5/6 ) and re-test.Then qualify the Cable run from the switch
to the Network drop , make sure all is well . Plug the 7975 into a diff rent
drop and observe behaviors.
            If the cables check out the problem is most likely the switch port
on the 7975. Regards,
                                                          Karl.
