We have a group of staff that rotate on-call duties. In the past they would setup IVR to allow customers to contact on-call in an emergency and that would ring to a cell phone they manually rotated amongst each other. I am trying to assemble a solution that would allow them to use their personal cell phones and easily sign in or out of the "after hours call queue" as needed (i.e. when they are on call they would sign in). Has anyone tackled this and come up with a simple user friendly solution?

I am planning to use call queue and then train them to use the "Do not accept call queue calls" option in the user portal. But that is not exactly user friendly. In the old days we had third party apps we would use that plugged into your PBX to allow people to sign in and out of the after hours on-call via a simple web page or by dialing in and following voice prompts.

Thanks for brainstorming with me!
