Configuring media flow protocols for SIP calls
Configuration prerequisites

Configuration procedure
To specify the media flow protocols for SIP calls:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter voice view.
voice-setup N/A
3. Enter SIP client view.
sip N/A
4. Specify the media flow
protocols for SIP calls.
media-protocol { rtp | srtp } *
Optional.
By default, RTP is adopted.
After you have specified both the
RTP and SRTP protocols as the
media flow protocols for SIP calls,
if the device is the call initiator,
both media flow protocols are
carried in the INVITE message for
the receiver to select. If the device
is the call receiver, the SRTP
protocol is applied for media flow
negotiation. If the negotiation fails,
the RTP protocol is applied.
