IVR to dial a mobile, if no answer then dial a different one

Hi there

I am trying to get our system to do the following:

On choosing option 0, dial a mobile number. If there is no answer after 30 seconds, dial a different mobile number.

I have tried a few different methods but didn’t get much success.

At the moment I have “dial 0 for the first person, or dial 1 for the second person” but I am hoping there is a way to tie this down properly.

Any help will be so greatly appreciated!

Thanks

setup fake sip extensions for each cell phone and add a followme feature to each extension that contains the cell #

then add those fake sip extensions to a ring group.
