Hello. I have an MICS with 7.0 software. We have added a new expansion cabinet, 6-port fiber card and 2 line cards. All of the new lines are causing a weird disconnect issue.
When someone answers the ringing phone, they are connected and talking to the person, but the phone continues to ring as if it were not answered on the other extensions. When you pick up the ringing line (after it has been answered at another extension), there is just dead air and it continues to ring on the rest of the extensions.
We've reviewed the programming and supervision is turned on. When we disconnect the cabinet, the original lines work fine. We have swapped out the DS cards, expansion cabinet and fiber card with different ones - but we still have the issue.
The minute we plug the expansion cabinet back in - all of the lines are effected.
We had the phone company verify the signaling is the same on the new lines as on the old.
Has anyone else experienced this? Any ideas on what to try?
