SIP Settings
SIP Registration This parameter controls whether the GXW410x needs to send REGISTER messages
to the SIP Server. The default setting is “Yes”.
Unregister on Reboot Default is No. If set to yes, the SIP user’s registration information will be cleared 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 Failure
Retry Wait Time This parameter is mostly used by Service Providers. It prevents message REGISTER
overload 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.
SIP Transport User can select UDP or TCP. Please make sure you’re SIP Server or network
environment supports SIP over the selected transport method. Default is UDP.
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.
Caller Request Timer If selecting “Yes” the phone will use session timer when it makes outbound calls if
remote party supports session timer.
Callee Request Timer If selecting “Yes” the phone will use session timer when it receives inbound calls with
session timer request.
Force Timer If selecting “Yes” the phone will use session timer even if the remote party does not
support this feature. Selecting “No” will allow the phone to enable session timer only
when t
he remote party support this feature. To turn off Session Timer, select “No” for
Caller Request Timer, Callee Request Timer, and Force Timer.

Force INVITE Session Timer can be refreshed using INVITE method or UPDATE method. Select

Enable 100rel The use of the PRACK (Provisional Acknowledgment) method enables reliability to be
offered to SIP provisional responses (1xx series). This is very important if PSTN inter-
networking is to be supported. A user’s request to use reliable provisional responses
is invoked by the 100rel tag which is appended to the value of the required header of
initial signalling messages.

Contact
Default is NO. If set to YES, then for Attended Transfer, the “Refer-To” header uses
the transferred target’s Contact header information.

messages from the peered SIP server.
