Enhancing Security

preventing calls being made from the outside via Voicemail access in IP Office mode

by  Westi  Posted    (Edited  )
There have been many questions about this and usually they are answered with: not possible with the IP Office as it is secure.
Intuity mode does not have this option but it should also be programmed this way as the mailbox has outcalling notification and can do the same thing when a message is left

The voicemail code should be secure (not 1234, 2580, 1590 or the 3 digit extension with 1 digit added) to avoid people hacking into it and being able to listen to your messages and access outcalling options.

Callers can leave a message and log into the voicemail pressing ** to call back the sender because of the caller ID (only IP Office mode)
that can be prevented by changing the outcalling of the system via the system shortcodes. (Information thanks to intrigrant, give him a star for it on a post)

[code ]9N
Dial
N
ARS or Line ID[/code]
should be changed to
[code ]9N
[color #EF2929]Barred[/color]
N
ARS or Line ID[/code]

This will prevent the system from outcalling at all.
then add shortcodes for allowed numbers like 911 or other emergency codes
[code ]911
dial
911
ARS or Line ID[/code]
also if outcalling is setup on any mailboxes these numbers [color #4E9A06]MUST[/color] be setup as system shortcode as well

Now to the good stuff to make users call out again
assign a user shortcode (best done via user rights)
Code: 
 9N          looks familiar, doesn't it
dial
N
ARS or Line ID
this way the outcalling for anything is strictly allowed to users

to allow any number for the system to be dialed you can set area codes or any other parameters that make sense for your setup via system shortcodes

Code: 
9234N               this will allow calls only to area code 234
Dial                you can change the area code to match your area or
234N                just make it 9xxxxxxx if you have 7 digit dialing
ARS or line ID      in your area so that you allow local calls

with this information also keep in mind to change all default passwords if the system is used on a network.
