I purchased a cisco UC320 as a one stop shop answer to our phone system.
I need to divert unanswered extensions to an external number - a mobile for instance.
Currently I can see no way to do this.
I have 2 analog external lines connected and no VOIP lines - thinking about maybe having these at a later date.
Any suggestions - I have tried all the obvious.
When I attempt this from the cfwd button on the phone then I try to enter my number all I get is invalid number.
320 is set up in "Key System" mode
