Blacklist
Blacklist is used to block an incoming or outgoing call. If the number of incoming or
outgoing call is listed in the number blacklist, the caller will hear the following prompt:
“The number you have dialed is not in service. Please check the number and try
again”. The system will then disconnect the call.
You can add a number with the type: inbound, outbound or both.

Callback Settings
1)
If you’d like to use callback feature, please make sure it’s enabled on the
IP->Port or Port->IP/Port route setting panel.
2) No callback rules needed to be set if the trunk supports call back with the caller ID
directly.
3) Add Callback numbers, then callback will work for the added callback numbers.
Tick “Allow All Numbers”, callback feature will work for all numbers.
the call is placed. For example, if a trunk requires 10-digit
dialing, but users are more comfortable with 7-digit dialing,
this field could be used to prepend a 3-digit area code to all
7-digit phone numbers before calls are placed.
