DESCRIPTION

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.
