Just installed an OS7100 for customer. 3 analog Comcast hunt lines connected to system. Customer has a google voice number advertised as their main number and it's pointed to line 1 on the system.

When ring plan 1 (night mode,rings to 519) is set and caller dials google voice number, the call just rings no answer and never goes to main greeting (line 1 button flashes). When ring plan 2 is set(day mode, rings to 501)the call rings thru and overflows to main greeting after 4 rings. I tried putting a delay in night mode but call never goes to greeting.

However if I call the analog number direct everything works fine.
