Service Domain Select Disable to not use a SIP service domain or select Define
service domain and 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.
Outbound Proxy Enter the IP address or domain name of the outbound proxy server
provided by your VoIP service provider. You can use up to 127 printable
ASCII characters. It does not matter whether the SIP server is a proxy,
redirect or register server. If you choose not to use an outbound proxy
server, select
Disable .
Outbound Proxy
Port Enter the outbound proxy’s listening port number, if your VoIP service
provider gave you one. Otherwise, leave it as the default ‘5060’.
If the outbound proxy is disabled, then this port will be ignored.
DTMF Mode Control how the X2002 handles the tones that the IP phones on your
network make when they push their buttons. One use of the tones is to
distinguish between numbers when trying to dial a PSTN phone number.
You should use the same mode as your trusted peer. The choices are:
• rfc2833 - Follow the RFC 2833 standard and send the DTMF tones
in RTP packets.
• inband - Send the DTMF tones in the voice data stream. This 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.
• info - Send the DTMF tones in SIP messages.
Privacy Select Disable to display caller ID as displayed in this screen’s
CallerID Viewer field. Select Enable to replace the caller’s name and
number with “Anonymous”. For example,
“Anonymous”<Anonymous@172.1.1.253>.

you were given information by your SIP service provider.
Channel-limit Specify the maximum number of SIP calls (1~128) allowed to be made

Timer
Select this activate the X2002’s session timer. If you encounter
connectivity issues with your network or Internet, then it is suggested
that you use the session timer.
Minimum SE Enter the minimum session expiry time in seconds. The allowable range
is 90~1800 seconds.
When an incoming call requests a session expiry time that is lower than
this, the X2002 uses this value instead.
