An example of creating "personal blacklist" function in the Asterisk (Elastix)

In this example, we add a function "personal blacklist" in /etc/asterisk/extensions_custom.conf  for followme calls (in the previous post, we added a feature "out of office")

Example:
Users phones: 10XXX

Then users can use this function from phones:
*13 - add
*14 - remove

1. Add to /etc/asterisk/extensions_custom.conf enable and disable blocks

[from-internal-custom]

;personal blacklist
exten => *13,1,Goto(personal-blacklist-add,s,1)
exten => *14,1,Goto(personal-blacklist-remove,s,1)

2. Add to /etc/asterisk/extensions_custom.conf check blocks in Followme
