Usage guidelines
You can configure source interface binding both globally (by using the bind command in SIP view) and
for a specific VoIP entity (by using the voice-class sip bind command in VoIP entity view). The
configuration in VoIP entity view takes precedence over the global configuration. A VoIP entity uses the
global configuration only when source interface binding is not configured in VoIP entity view.
If the specified source interface does not have an IP address or its IP address is invalid, the device uses
the default configuration.
The following table describes how source interface binding works in different conditions:
Condition Result
Configure a new source interface when
ongoing calls exist.
• The new source interface takes effect for subsequent SIP
media sessions but does not take effect for existing SIP media
sessions.
• The new source interface immediately takes effect for all SIP
signaling sessions.
The bound source interface is shut down.
The source interface binding function does not take effect, and
the default setting is restored.
The IP address of the bound source interface
or the bound source interface is removed.
The physical or link layer state of the bound
interface is down.
The bound source interface obtains a new IP
address from the DHCP or PPPoE server.
The new IP address is used as the source IP address.
Configure a new source interface during SIP
registration.
The new source interface takes effect for subsequent
registrations.
Examples
# Specify Dialer 0 as the source interface for outbound SIP messages.
<Sysname> system-view
[Sysname] voice-setup
[Sysname-voice] sip
