Activate Profile When set to Yes the SIP Profile is activated.
Profile Name A name to identify a Profile.
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-410x 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.
Use DNS SRV: Default is No. If set to Yes the client will use DNS SRV to look up server.
User ID is Phone If the GXW-410x has an assigned PSTN telephone number, this field should be set
Number 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.
This parameter controls whether the GXW-410x needs to send REGISTER
SIP Registration
messages to the proxy server. The default setting is "Yes".
Unregister on Default is No. If set to yes, the SIP user's registration information will be cleared on
Reboot reboot.
Register This parameter allows the user to specify the time frequency (in minutes) for the
Expiration GXW-410x to refresh its registration with the specified registrar. The default interval
is 60 minutes (or 1 hour). The maximum interval is 65535 minutes (about 45 days).
Local SIP port This parameter defines the local SIP port the GXW-410x will listen and transmit.
The default value for Account 1 is 5060. It is 5062, 5064, 5066 for Account 2,
Account 3 and Account 4 respectively.
NAT Traversal This parameter defines whether the GXW-410x NAT traversal mechanism will be
activated or not. If activated (by choosing "Yes") and a STUN server is also
specified, then the GXW-410x will behave according to the STUN client
specification. Under this mode, the embedded STUN client inside the GXW-410x
will attempt to detect if and what type of firewall/NAT it is sitting behind through
communication with the specified STUN server. If the detected NAT is a Full Cone,
Restricted Cone, or a Port-Restricted Cone, the GXW-410x will attempt to 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-410x 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.
Proxy-Require SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.
Early Dial Default is No. Use only if proxy supports 484 response.
Session Grandstream implemented SIP Session Timer. The session timer extension
Expiration enables SIP sessions to be periodically "refreshed" via a SIP request (UPDATE, or
re-INVITE. Once the session interval expires, if there is no refresh via a UPDATE or
re-INVITE message, the session will be terminated. Session Expiration is the time
(in seconds) at which the session is considered timed out, if no successful session
refresh transaction occurs beforehand. The default value is 180 seconds.
