Configuring a Domain
Name for the SIP UA
During the communication between caller and callee, dual tone multi-frequency
(DTMF) codes can be transmitted transparently between them in two ways:
in-band and out-of-band. In the in-band approach, DTMF is encoded in RTP voice
packets, and in the out-of-band approach, in SIP messages.
To implement DTMF out-of-band transmission, you need to configure it for the
VoIP entity on the calling UA and for the corresponding POTS voice entity on the
called UA.
Configuration prerequisites
The configuration at the SIP server end is completed.
Configuration procedure
Follow these steps to configure the out-of-band SIP DTMF transmission mode:
To do...

For more information about the outband sip command, refer to
on page 2243.
You may specify a source IP address for the packets sent by the SIP UA. This source
IP address is usually the address of a logical interface such as a loopback interface
because this type of interface is always up.
Configuration prerequisites
The configuration at the SIP server end is completed.
Configuration procedure
Follow these steps to configure a source IP address:
To do...
Enter system view
Enter voice view
Enter SIP client view
Bind a source IP address to the
UA to send packets
SIP addresses can be domain names or IP addresses. As IP addresses of SIP UAs are
more likely to change, domain name addresses are preferred where fixed SIP
addresses are desired.
