DTMF Mode
Control how the ZyXEL Device handles the tones that your telephone makes when
you push its buttons. You should use the same mode your VoIP service provider
uses.
RFC 2833
- send the DTMF tones in RTP packets
PCM
- send the DTMF tones in the voice data stream. This method works best
when you are using a codec that does not use compression (like G.711). Codecs
that use compression (like G.729) can distort the tones.
SIP INFO
- send the DTMF tones in SIP messages
STUN
Active
Select this if all of the following conditions are satisfied.
•
There is a NAT router between the ZyXEL Device and the SIP server.
•
The NAT router is not a SIP ALG.
•
Your VoIP service provider gave you an IP address or domain name for a
STUN server.
Otherwise, clear this field.
Server Address
Enter the IP address or domain name of the STUN server provided by your VoIP
service provider.
Server Port
Enter the STUN server’s listening port, if your VoIP service provider gave you one.
Otherwise, keep the default value.
Use NAT
Active
Select this if you want the ZyXEL Device to send SIP traffic to a specific NAT
router. You must also configure the NAT router to forward traffic with the specified
port to the ZyXEL Device. This eliminates the need for STUN or a SIP ALG.
Server Address
Enter the public IP address or domain name of the NAT router.
Server Port
Enter the port number that your SIP sessions use with the public IP address of the
NAT router.
Outbound Proxy
Active
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.
NAT Keep Alive
Active
Select this to stop NAT routers between the ZyXEL Device and SIP server (a SIP
proxy server or outbound proxy server) from dropping the SIP session. The ZyXEL
Device does this by sending SIP notify messages to the SIP server based on the
specified interval.
Keep Alive with
SIP Proxy
Select this if the SIP server is a SIP proxy server.
Keep Alive with
Outbound Proxy
Select this if the SIP server is an outbound proxy server. You must enable
Outbound Proxy
to use this.
Keep Alive Interval Enter how often (in seconds) the ZyXEL Device should send SIP notify messages
to the SIP server.
