Markdevoll,
I find that question to be an odd one to hear from a certified technician, so I will expand on DND ONs answer; which is the easiest solution.
Do a Call Pickup [Reverse Transfer Code: 4 is the default] from the Hunt Group pilot number. So if the Hunt Group is 2000 then they would dial 42000 and the ringing call will be pulled to them. Alternately you could give them a button for the Hunt Group and then they would press 4 and that button or you could create a personal speed dial that dials 42000 and it pulls the call to them.
I have had customers tell me that solution is too much, go figure, and they wanted a one button push that gave a visual indicator. You can do this depending on how the Hunt Group is setup, but if the above solution works for them then slowly back away and then make a run for it.
Thanks,
TE
