Item Description
ID Enter the ID of the call-out route.
Destination Number
Prefix Enter the destination number prefix and length. Suppose the destination number
prefix is 4100, and the number length is 6. This configuration matches destination
numbers that are 6-digit long and start with 4100.
A dot can be used after a number to represent a character. This configuration does
not support other characters.
Number length
Destination IP address
Enter the destination IP address and port number.
Port Number
Area Prefix Enter the area prefix added before the calling numbers of outgoing calls.
Area prefix
When the local SIP server is connected to the extranet, 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.
Select Voice Management > SIP Local Survival > Area Prefix from the navigation tree to access the page
as shown in Figure 771 .
