Asterisk Extension Setup

=Asterisk extension setup=

In order for all of the features that we want in asterisk to work, 4 extensions and a ring group must be set up for each extension. The general flow is this: Home (SIP or IAX2) extension = 7xx M21 (SIP) phone extension = 3xx dialin (Custom) ext = 2xx followme (Custom) ext = 5xx ring group = 1xx
 * 1) Call comes in
 * 2) Caller dials the 2xx extension
 * 3) This forwards (follow-me) to the 1xx group which rings the 3xx phone in the office and the 7xx extension at home (if any)
 * 4) If this times out, the fall-through is to the 5xx extension's follow-me which calls a home or cell phone if wanted
 * 5) The fall-through if this fails is to the 2xx voicemail.

Enter the 3xx and 7xx SIP extensions without any voicemail, but with the proper secret in place

In the 1xx ring group, the 3xx and the 7xx extensions go into the extension list and the follow-me points directly to the follow-me of the 5xx extension.

2xx extension gets the 1xx ring group in its follow-me and the name of the person properly put in and voicemail activated

5xx extension has only a follow-me entry in which confirm calls is checked and the home/cell number goes with a # sign at the end. The Destination if no answer is the voicemail box on the 2xx extension.

This makes a big circle: 2xx (follow me) -> 1xx -> 3xx/7xx -> 5xx (follow me) -> cellphone -> 2xx voicemail. That means that these cannot be created in any simple order and it actually takes creates and follow-up edits to create each of the 4 extensions, 2 follow-mes and 1 ring group involved for each person.
