Grandstream Networks GXW-410xv

TABLE 11: GRANDSTREAM CONFIGURATION PAGE DEFINITIONS

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-410xv 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

Number

If the GXW-410xv 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-410xv 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 will be cleared on

reboot.

Expiration

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

GXW-410xv 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-410xv 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-410xv NAT traversal mechanism will be

activated or not. If activated (by choosing “Yes”) and a STUN server is also

specified, then the GXW-410xv will behave according to the STUN client

specification. Under this mode, the embedded STUN client inside the GXW-410xv

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-410xv 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-410xv 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.
