Wow...
I also had problems with two networked 100's that had version 2.69.
The most common problem was as follows...
CO Trunk call comes into System A, transfers across the network via the T1 to the Central Operator on System B. Central Operator does an announced transfer back across the network to an extension at Site A... but the her call goes back across the SAME channel and the caller is able to hear the conversation between the Central Operator and the extension. Then when Central Operator releases the call to the extension the caller is dropped and has to call back.
The customer got burned bad once because the person who answered the extension had some "unpleasant" things to say about the caller... who heard EVERYTHING!
I spent two weeks with Samsung and they were unable to find any solution!
