SIP Server
SIP Server’s IP address or Domain name provided by VoIP service provider.
Outbound Proxy IP address or Domain name of Outbound Proxy, or Media Gateway, or Session
Border Controller. Used by GXW–400x for firewall or NAT penetration in different
network environments. If symmetric NAT is detected, STUN will not work and
ONLY outbound proxy can correct the problem.
SIP transport
User can select UDP or TCP or TLS. Please make sure you’re SIP Server or
network environment supports SIP over the selected transport method. Default is
UDP.
NAT Traversal
This parameter defines whether the GXW–400x NAT traversal mechanism is
activated or not. If activated (by choosing “Yes”) and a STUN server is also
specified, then the GXW–400x performs according to the STUN client specification.
Under this mode, the embedded STUN client will detect if and what type of
firewall/NAT is being used. If the detected NAT is a Full Cone, Restricted Cone, or
a Port-Restricted Cone, the GXW–400x will use its mapped public IP address and
port in all of its SIP and SDP messages.
If the NAT Traversal field is set to “Yes” with no specified STUN server, the GXW–
400x will periodically (every 20 seconds or so) send a blank UDP packet (with no
payload data) to the SIP server to keep the “hole” on the NAT open.
Use DNS SRV:
Default is No. If set to “Yes” the client will use DNS SRV to look up server.
User ID is Phone
Number
If the GXW–400x has an assigned PSTN telephone number, this field should be set
to “Yes”. Otherwise, set it to “No”. If “Yes” is set, a “user=phone” parameter will be
attached to the “From” header in SIP request.
SIP Registration
This parameter controls whether the GXW–400x needs to send REGISTER
messages to the proxy server. The default setting is “Yes”.
Unregister on
Reboot
Default is No. If set to “Yes”, the SIP user’s registration information is cleared on
reboot.
