Rollover to line 2 if line 1 busy?

[FarmerBob]

Maybe I don't understand, but with the cloned line....when we are on a call on either line and another call comes in, not only will the CID show up, but the other line will ring...allowing the call to be answered.
This is normal functioning for me without any additional settings.

What I think people are looking for other than the way it is, which is what I would like also, is when a call comes in the line you are on does nothing. You wouldn't know that a call was coming in, other than the other line ringing. (That call waiting tone is horrendous and interrupts my call.) Then when the second/Cloned line rings, it's as if it were a totally separate line and an unassociated call. I'm wondering if I can turn off Call Waiting, it might cause this to happen that way?

UPDATE:
In the VPanel, there is an area under Beta > Misc = FXS Port Control where the option looks to enable what we are asking for. I have shut off Call Waiting for both lines with Busy forward to VoiceMail default. If this does what it implies the outcome should be exactly what, at least what I am looking for.
