Problem reports started coming in on Tuesday of this week, 5 days after introducing the new (local) Sub to the mix and moving everyone over to it. No problem reports last Friday or this past Monday. The original sub was 150 miles away and prior to adding a local sub everything was registering to the local *Pub* (bad design I know, but I didn't do it, the VAR did) - anyway after adding the 2nd sub (which is now local to us) we moved everything over from the Pub to the local Sub. Recent changes: Last week we added the 2nd sub. Last night we forced everything over to the *Pub* but today (Thurs) we're still getting isolated reports. On internal failures 1 party will see 'UCM Down' the other party will see 'Fail'. This is occurring internally within the local network on station to station calls as well as on external (trunk) calls. Yesterday (Wednesday) about 5 more complaints, various but similar symptoms, some reporting 1-way audio, some reporting dropped call.

Second Sub recently added (middle of last week)ДЇirst report 2 days ago (this past Tuesday), 1 enduser reported a dropped call, her phone (7942) shows UCM fail then goes to re-registering
