DESCRIPTION
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.
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).
Enter the IP address or domain name of the SIP outbound proxy server.
Enter the SIP outbound proxy server's listening port, if your VoIP service provider
gave you one. Otherwise, keep the default value.
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.
Keep the default value, 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.
This field controls how the ZyXEL Device handles fax messages.
Select this if the ZyXEL Device should use G.711 to send fax messages. The peer
devices must also use G.711.
Select this if the ZyXEL Device should send fax messages as UDP or TCP/IP
packets through IP networks. This provides better quality, but it may have inter-
operability problems. The peer devices must also use T.38.
Select which call forwarding table you want the ZyXEL Device to use for incoming
calls. You set up these tables in VoIP > Phone Book > Incoming Call Policy.
Select the check box if you want to specify what tone people hear when they call
you. The ZyXEL Device provides a default tone, but you can add additional tones
using IVR. See Section 11.8 on page 157
Select the tone you want people to hear when they call you. You should setup
these tones using IVR first. See
