Chapter 9: VoIP QoS

VoIP QoS

The Branch Gateway provides voice services over IP data networks using VoIP. VoIP is a
group of protocols for transmitting and receiving various types of voice data over an IP network.
VoIP includes protocols for transmitting and receiving the following types of information:
• Digitally encoded voice data
• Call signalling information
• Call routing information
• QoS information
VoIP uses the RTP and RTCP protocols to transmit and receive digitally encoded voice data.
For more information about configuring RTP and RTCP on the Branch Gateway, see
RTCP configuration
You can use many types of telephones and trunks that do not directly support VoIP. The Branch
Gateway translates voice and signalling data between VoIP and the system used by the
telephones and trunks.

RTP and RTCP configuration
VoIP uses the RTP and RTCP protocols to transmit and receive digitally encoded voice data.
RTP and RTCP are the basis of common VoIP traffic. RTP and RTCP run over UDP and incur
a 12-byte header on top of other (IP, UDP) headers. Running on PPP or frame relay, these
protocols can be compressed.
