I have just performed a clean install of our UC500 with CCA 2.0 and software upgrade package 7.0.3. The system is set up as a Key System with the CO Lines configured on everyones phone, along with their primary internal extensions. It was conifgured completely using the CCA.
Recently, we have had calls drop when they are answered on an outside line, and transferred to an internal extension. The call drops right when the internal extension that it is being transferred to picks up. It does not occur every time, kind of hit and miss.
Any ideas why this could be happening, and why it seems to be random?
