• Min. Accept Digits— The minimum number of digits that must be dialed to
be accepted as a correct number. This includes the prefix.
• Max. Accept Digits— The maximum number of digits that can be dialed to
be a valid phone number. This includes the prefix.
• Delete Digits— The number of digits at the beginning of the dialed number
that will be taken off. For example, if you dial the number 88-0930-123-456
and have a rule with prefix 88 and set the number of digits to be deleted as 2,
then it will dial the number without the 88 prefix at the beginning and insert
the 2 in its place.
• Insert Digits— The digits that will be inserted at the beginning of the dial-
string after the specified digits are first deleted.
• Type— There are 3 types of dial plans: PSTN, VoIP, and block. You can
create dial plans for PSTN and VoIP numbers in addition to dial plans that
you want to block. For example, if you want to block a phone number with a
certain prefix, you need only to enter the prefix and the Min. and Max.
Accept Digits and select Block under the Type column.

The phonebook allows you to filter calls from specified IP addresses. Enter the IP
addresses in the Call ID field and then decide whether you want to allow or deny
those enabled callers. You can also organize the calls by ring group (default, family,
friend, and colleague).
