Hello group, I’m developer myself but creating dial plans is little bit different I guess 🙂
I created very simple automated attendand (with a help of book), below is code. But logic is simple:

Depending on time – I want:
If during business hours – give them menu and handle extensions If after hours – give them message and take to voicemail.

This dial plan accomplishes just that.

What I don’t like is side behavior of this plan When after hours – I can still press 1/2/3 and go into Sales/Support queue or to operator, etc. It’s probably OK to allow dialing of extensions of actual users (101, 102, etc)
But I don’t want them to dial operator (0) or 1,2,3 and such.

How do I fix it?

Thank you!
Ivan
