DESCRIPTION
Enter the IP address or domain name of the SIP register server, if your
VoIP service provider gave you one. Otherwise, enter the same address
you entered in the SIP Server Address field. You can use up to 95
printable ASCII characters.
Enter the SIP register server's listening port number, if your VoIP
service provider gave you one. Otherwise, enter the same port number
you entered in the SIP Server Port field.
Enter the SIP service domain name. In the full SIP URI, this is the part
after the @ symbol. You can use up to 127 printable ASCII Extended
set characters.
Enter the listening port number(s) for RTP traffic, if your VoIP service
provider gave you this information. Otherwise, keep the default values.
To enter one port number, enter the port number in the Start Port and
End Port fields.
To enter a range of ports,
• enter the port number at the beginning of the range in the Start
Port field.
• enter the port number at the end of the range in the End Port field.
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.
RFC2833 - 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 and G.726) can
distort the tones.
SIPInfo - send the DTMF tones in SIP messages.
Select the transport layer protocol (TCP, UDP or TLS) used for SIP.
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 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 re-translating 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.
