Outbound Server Select Enable if your VoIP service provider has a SIP outbound server to handle voice
calls. This allows the LTE3311 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
LTE3311 to keep it from re-translating the IP address (since this is already handled by
the outbound proxy server).
Outbound Proxy Enter the IP address or domain name of the SIP outbound proxy server.
Subscribe for MWI Select Enable 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 the MWI
(Message Waiting Indication) feature.
Refresh Time for
MWI
Enter the number of seconds the SIP server should provide the message waiting service
each time the LTE3311 subscribes to the service. Before this time passes, the LTE3311
automatically subscribes again.
MWI Server URI Enter the domain name of the MWI server.
Registration Status This shows the current registration status of the SIP account.
