Configuring an area prefix

When the local SIP server is connected to the public network, external users can originate calls to
internal users registered with the local SIP server. For calls from external users to internal users, the
local SIP server removes the configured area prefix from each called number to converts it to an
internal short number. For example, if an external user dials number 01050009999, the local SIP
server checks whether any area prefix matches the called number. If the area prefix 0105000 is
available, the local SIP server removes the prefix 0105000 from the called number and sends the call
to 9999.
To configure an area prefix:
Step
1. Enter system view.
2. Enter voice view.
3. Enter SIP server view.
4. Configure an area prefix.
Configuring a call route
The local SIP server uses a static routing table to forward outgoing calls. If the called number
matches a static route, the local SIP server forwards the call to the specified destination. The called
number does not need to register on the local SIP server. For example, as an external number,
5552000 does not need to register on the local SIP server. Configure a static route entry with the
area prefix of 333 and called number of 5552000 on the local SIP server. Upon receiving a call from
local number 1000 to external number 5552000, the local SIP server adds the area prefix 333 to the
calling number, and forwards the call to the destination specified in the static route entry.
To configure a call route entry:
Step
1. Enter system view.
