Configuring Source Ip Address Binding For Sip Messages - HP FlexNetwork MSR Series Configuration Manual

Configuration prerequisites
If a SIP server is used to forward calls, complete the configurations on the SIP server. To implement
bidirectional DTMF out-of-band transmission, configure it in the VoIP entity on the calling UA and in
the corresponding POTS voice entity on the called UA. For specific configurations, see
out-of-band SIP DTMF transmission
Configuration procedure
To configure the out-of-band SIP DTMF transmission mode:
Step
1. Enter system view.
2. Enter voice view.
3. Enter voice dial program
view.
4. Enter voice entity view.
5. Configure the out-of-band
SIP DTMF transmission
mode.

Configuring source IP address binding for SIP messages

Perform this task to specify a source IP address for SIP signaling or media messages 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.
Source IP address binding is supported on Layer 3 Ethernet interfaces, 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.
