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 Layer 3—IP Services Configuration Guide.
For more information about PPPoE, see Layer 2—WAN Configuration Guide.
Configuration prerequisites
• Configure a SIP trunk account for registration. For more information, see "Configuring a SIP trunk
account for registration."
• Configure call routes for outbound calls. For more information, see "Configuring call routes for
outbou
nd calls."
