Grandstream Networks GXW-410x

SIP Registration This parameter controls whether the GXW-410x 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.

Expiration This parameter allows the user to specify the time frequency (in minutes) for the

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

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 the remote party support this feature. To turn off Session Timer, select “No”

for Caller Request Timer, Callee Request Timer, and Force Timer.
