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.
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.
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.
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,

Select Siemens early media support to turn on support for Seimens
early media.
Enter this (0~127 alphanumeric characters) to inform the SIP server
that this device is behind a firewall or NAT device. Fill this field in only if
you were given information by your SIP service provider.
Specify the maximum number of SIP calls (1~128) allowed to be made
through this trunk connection at one time.
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.
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.
