I have just installed a 6.0 system with swca keys 1-6 on ten m7310 sets, using these primarily to hold incoming calls at these sets until someone is able to handle the call. Several times in the past week three or four of these keys lock up and cannot be released. They show "busy on another call" but all channels on the Pri are idle or have another conversation on them. Can't do anything to release these locked keys.
Thanks in advance Joe
