Trying to have a gate ring all extensions
For 20 seconds and then forward to a cell phone

I guess the first the question is, is this best achieved by having the gate act as a telco line or an extension?

From there what would be the best set up.

I am not an installer. The installer is unavailable for a while and we are wanting to achieve this if possible.

Thank you
