Call Forward if Busy from CO Line to another CO Line Опции

[HatemHusam]

Hello Team,

How are you today

1. I would like to know how to transfer a call from CO1 to CO2 if CO1 is busy ?

2. one more thing, I have something unusual, if some one called CO1 or CO2 or CO3 ... etc, and no one answer that call the Flex1 button keeps flashing and we will not be able to use that CO unless the attendant station pickup and phone and put it again !! any idea about that ?

The user calls on your PBX 1 CO line, but the line is busy.
The CO switch the incoming call to another line.
Right?
On analog lines it is possible only on the side of the provider
