On one of our clusters running 5.1, we have an issue at one of our offices. This particular office has multiple shared line appearances between users (dozens of phones with anywhere from 5 to 10 shared lines on each phone -- with up to 10 shared lines per DN). Intermittently, when a shared line is picked up, another phone with that shared line continues to ring until the phone is hard reset.
I'm not local to that office, so am relying on end users to explain the issue. All of the phones are 7960's with SCCP load P00308000800. All of the shared lines have the primary appearance on line 1, while the other appearances are on other lines -- some on 7914's.
I'm at a complete loss on this one. Any ideas??
