Second Line and Simul Ring

[JimDog]

Maybe this will help...?

Default behavior with primary number and virtual number (i.e. cloned line)
An incoming call on either phone number will ring both the Line 1 and Line 2 ports on your adapter simultaneously. If either line is active in a call while another calls comes in on either phone number, the line in use will hear a call waiting beep and the unused line will ring.

Behavior with a virtual number assigned as a 2nd line
An incoming call on your primary phone number will ring only on Line 1. If Line 1 is in use while another call comes in to your primary phone number, Line 1 will hear a call waiting beep. Line 2 will not ring.

An incoming call on the virtual number will ring only on Line 2. If Line 2 is in use while another call comes in to the virtual phone number, Line 2 will hear a call waiting beep. Line 1 will not ring.

Note: With either option, there is no "busy" status per se like there is with Verizon. By default, an incoming call while the line is already in use will trigger a call waiting beep, a ring on the second line (if using cloned line) and forward to voice mail if neither are answered.
