If my business is busy I forward the phones from the business to an employee who is on calls cell phone. What is the difference between this and the new queue to queue overflow feature? And which makes more sense for what I'm using it for..
I have double checked with our Tier 3 engineers and Danno is exactly correct. The small delays in ringing each users phone would likely cause issues such as continued ringing for some users, after the call is answered.
simultaneous ringing uses a lot of resources and could present issues with continual ringing after answered - depending on the network router and/or ISP - usually caused by sip invite/refer problem.
