SolutionQuality voice traffic has different network requirements
than does typical network traffic. The Meru Wireless LAN System is
designed to automatically provision voice traffic with a level of QoS
appropriate for voice calls. The result is that VoIP traffic works much
better over a Meru Wireless LAN System than it does over most WLANs. The
controller watches the traffic passing through it and when it sees
packets from stations to servers on ports reserved for SIP or H.323
service, it tracks subsequent communication in that sequence and
provisions the VoIP call with a level of service appropriate for a VoIP
call. The port numbers
watched are:
5060 for SIP service
(UDP)
1720 for H.323 service
(TCP)
5200 for Vocera
(UDP)
These are the standard port numbers for these
services. If your VoIP devices use these ports to communicate with their
servers, you do not need to configure VoIP QoS rules on your system. If
your VoIP devices and servers are configured to use different ports,
you will need to modify the QoS rules on the controller to match the
ports your system
uses.
