Configuring source address binding

Use source address binding to specify a source address for signaling and media flows initiated from
private SIP users to a SIP server group. Perform this task by using one of the following methods:
•
Static IP address binding—Uses a static address as the source IP address.
•
Interface binding—Uses the IP address of a source interface as the source IP address. In a
large-scale network, an interface obtains its IP address from a DHCP or PPPoE server. In this
scenario, you can use this method to configure an interface as the source of SIP signaling and
media flows to avoid manual configuration.
This feature is supported by Layer 3 Ethernet interfaces, Layer 3 Gigabit Ethernet interfaces, and
dialer interfaces.
For more information about DHCP, see HPE FlexNetwork MSR Router Series Comware 5 Layer
3—IP Services Configuration Guide.
For more information about PPPoE, see HPE FlexNetwork MSR Router Series Comware 5 Layer
2—WAN Configuration Guide.
