ABLE ROFILE AGE
Activate Profile When set to Yes the SIP Profile is activated.
Profile Name A name to identify a Profile.
SIP Server's IP address or Domain name provided by VoIP service provider.
SIP Server
Outbound Proxy IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border
Controller. Used by GXW410x 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.
If the GXW410x has an assigned PSTN telephone number, this field should be set to "Yes".
User ID is Phone
Otherwise, set it to "No". If "Yes" is set, a "user=phone" parameter will be attached to the
Number
"From" header in SIP request.
SIP Registration This parameter controls whether the GXW410x needs to send REGISTER messages to the
SIP Server. The default setting is "Yes".
Default is No. If set to yes, the SIP user's registration information will be cleared on reboot.
Unregister on
Reboot
Register Expiration This parameter allows the user to specify the time frequency (in minutes) for the GXW410x 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).
SIP Registration
This parameter is most used by Service Providers. It prevents message REGISTER overload
Failure Retry Wait
of SIP Server in case of downtime due to maintenance or power failure. By increasing
interval length, common message load is decreased. Interval range is 1 – 3600 seconds.
Time
NAT Traversal
This parameter defines whether the GXW410x NAT traversal mechanism will be activated or
not. If activated (by choosing "Yes") and a STUN server is also specified, then the GXW410x
will behave according to the STUN client specification. Under this mode, the embedded
STUN client inside the GXW410x 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 GXW410x 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 GXW410x 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 Expiration Grandstream implemented SIP Session Timer. The session timer extension 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.
Min-SE
The minimum session expiration (in seconds). The default value is 90 seconds.
If selecting "Yes" the phone will use session timer when it makes outbound calls if remote
Caller Request
Timer
party supports session timer.
