Auto-VoIP Configuration
Auto-VoIP automatically makes sure that time-sensitive voice traffic is given priority over data
traffic on ports that have this feature enabled. Auto-VoIP checks for packets carrying the
following VoIP protocols:
• Session Initiation Protocol (SIP)
• H.323 (Prioritize only signaling packets)
• Skinny Call Control Protocol (SCCP)
All three protocols are checked during the signaling, call identification stage. Once the VoIP
call is established, only the SIP and SCCP protocols are checked.
This feature supports up to
48 bidirectional VoIP calls.
V
oIP frames that are received on ports that have the Auto-VoIP feature enabled are assigned
to queue 3.
Auto-VoIP and QoS CoS/DiffServ mode features can co-exist and be activated at the same
time. If both features are active at the same time on the same port, the manual QoS
assignment might override the VoIP QoS assignment.
To configure the
Auto-VoIP parameters, use the Auto-VoIP configuration screen. The
Interface column specifies all the configurable Auto-VoIP interfaces.
The Traffic Class
displays the traffic class on which the received VoIP frames are marked.
 To enable Auto-VoIP:
