First time caller, long time reader…

I’m looking to leverage * voicemail application. I see other posts but never a firm answer. My question is:

How do I program SER to recognize “unavailable and/or busy” (similar to how * does this)? Then, if this

state is recognized, I want SER to re-direct the call to *. If I can figure this out, then I believe all I have to do with

* is set it up for no rings and do the normal “exten” commands. Seams pretty simple…

TIA and happy new year,
