phone number.

Phonebook Rules:
To meet the requirements of communicating with trunk gateway or other
applications, Phonebook has following characteristics to be noticed.
When the destination side is a terminal, for ex: IP Phone or soft phone, e164
number stands for exact destination phone number.
When the destination side is a gateway, for ex: T1/E1 gateway, e164 phone
number stands only for gateway prefix. That is, users have to continue to dial
destination number, following the prefix number. An example is as below: A is
a VoIP FXO gateway and B is a E1 Trunk gateway, which is connected to
PSTN with E1 PRI. There’s a record in A’s phone book
Index Name IP E164
1 B_gateway 192.168.1.2 0
-------------------------------------------------------------------------------------------
If users want to make a call to PSTN number “82265699”, they have to make
a call to connect to VoIP FXO gateway A, and then dial “082265699”. After
receiving the complete dialed number, VoIP FXO gateway A will search for its
Phone Book, find “0” as matched prefix, and then dial out to B’s IP address
directly with destination e.164 (phone number) “82265699”. Pleased be noted
that “0” is eliminated from VoIP FXO gateway itself.
Note:
Because of above characteristics, users have to take care of the number plan
very well to avoid the numbering conflict. If users already defined “0” for
specific trunk gateway, other terminal started with “0” shall be avoided, or the
number will be routed to the trunk gateway defined “0”.
