I am having a problem with a 128i. In a realty office, Line 10 is programmed to ring only at two extensions in the rental office. When the line rings and is picked up, the phone system immediately automatically puts the call on hold. Then, after 5 seconds, both phones start ringing again and then the call can be picked up and answered. I've looked all through the programming and can't find any setting that would do this. This doesn't happen with any of the other lines that ring at the reception phone. Does anyone have any ideas?
