More than occasionally I have a problem with what I can best describe as an out-of-sync issue. When I select the my connected 7975G phone (connected to a ISR 2901 with CME) on the W740 base, then hit the headset button on the 7975G base, it will begin to go on-hook and off-hook... cycling endlessly. I have to remove power from the base or try to re-cycle the power on the cisco base set. That only temporarily solves the problem.
I anyone knows if this is fixed in 7975G firmware, or there is something else to try, please share.
Thanks
