OS7400 + SVMi-20E.

If person A calls in and presses [1] for ring group 1, when person B calls in and selects an extension that exists in ring group 1, it immediately goes to voicemail for that extension if person A is still ringing.

Is there any way to supersede the ring group ring on an extension when another person dials an extension directly?

Thanks!
