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.

VoIP frames that are received on ports that have the Auto-VoIP feature enabled are assigned 
to queue 6.

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.
