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
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, 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.
Fax Option
This field controls how the ZyXEL Device handles fax messages.
G.711 Fax
Passthrough
Select this if the ZyXEL Device should use G.711 to send fax messages. The peer
devices must also use G.711.
T.38 Fax Relay
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.
