DSCP for SIP*
The SIP differentiated services

SIP signaling traffic is sent at a

important because SIP messages
travel over the same network as the
voice traffic. If this network is
congested, the voice data might
delay the SIP signaling packets,
increasing call setup time. Raising
the SIP packet priority in relation to
other traffic reduces the delay.
