trying to figure the subject out. I'd like 2 phones connected to the same ATA having the same number. If the first line is busy, the second line should accept the call.
short testing with UID0 and UID1 having the same number didn't succeed. If the first line is busy, incoming call gets busy signal even if the second line is idle.
Does anybody know how it can be done within ATA config or maybe at the central GW?
