DISA - Direct Inward System Access

DISA ()
Direct Inward System Access leaves out the people who call into the system and provides them with an internal dial tone.
DISA (password [context [callerid [mailbox [@-voice context ]]]])
DISA (file with a password, [callerid [mailbox [@-voice context]]]) provides a dial tone internal callers outside so that they can make calls as if calling from inside extension . Upon hearing the dial tone, an access code must be entered followed by the "#". If it is correct, the caller hears another tone, which is the system of dial tone and the caller can make and initiate calls.
[Caution] This type of access represents a serious threat to security and real and must be carefully considered and planned before use, but you should be used at all!
The option is a numerical code that access should be introduced to the caller to make calls. Following this syntax, all users on the floor using the same access code. If you want to allow access unsecured, enter the string "no password," instead of a real password.
The context option specifies the context in which it began the call is placed. If not provided, DISA () assumes that the context called disabilities.
The callerid option determines the number of mail (and the optional voice context) of a mailbox. If the mailbox containing new messages to the caller will hear a stuttered dial tone to indicate this.
Alternatively, you can use the password file to define multiple access passwords. Each line of this file can contain either an access code or a combination of an access code and a context, separated by the "|" character (pipe). If not specified the context, it is assumed disability.
If the caller is authenticated successfully with a valid access code, DISA () will start the call in the context specified.
