To give you a bit of background about our setup, we have 2x ring groups, one had 8 people in, the other has the same eight plus an additional 2x people. If someone is on the phone when the other phones start ringing, then finish their call. Their phone does not ring until the next ring group starts ringing. I've changed it so the ring groups ring for a shorter amount of time, however it's a bit of a work around. Basically we just need someone's phone to start ringing again as soon as they finish the call they are on. (If there is a call waiting) Does anybody have a better solution?
