11.6 SIP QoS Screen
Use this screen to maintain ToS and VLAN settings for the ZyXEL Device. To access this
screen, click
VoIP > SIP > QoS .
Enable Select this if your VoIP service provider has a SIP outbound server to handle voice
calls. This allows the ZyXEL Device to work with any type of NAT router and
eliminates the need for STUN or a SIP ALG. Turn off any SIP ALG on a NAT router
in front of the ZyXEL Device to keep it from retranslating the IP address (since this
is already handled by the outbound proxy server).
Server Address Enter the IP address or domain name of the SIP outbound proxy server.
Server Port Enter the SIP outbound proxy server’s listening port, if your VoIP service provider
gave you one. Otherwise, keep the default value.
MWI (Message
Waiting
Indication)
Enable Select this if you want to hear a waiting (beeping) dial tone on your phone when
you have at least one voice message. Your VoIP service provider must support
this feature.
Expiration Time Keep the default value for this field, unless your VoIP service provider tells you to
change it. Enter the number of seconds the SIP server should provide the
message waiting service each time the ZyXEL Device subscribes to the service.
Before this time passes, the ZyXEL Device automatically subscribes again.
