| Failover SIP Server |
|
|
| ||
|
| Failover SIP Server’s IP address or Domain name provided by VoIP Service provider. |
| |||
|
|
| This server will be used if the Primary SIP server becomes unavailable. |
| ||
|
|
|
|
|
|
|
|
|
|
| |||
| Prefer Primary SIP |
| Default is no. If set to yes it will register to Primary Server if registration with Failover |

|
|
|
|
|
|
|
| |||
| Outbound Proxy |
| IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border |
| ||
|
|
| ||||
|
|
| Controller. Used by GXW40XX 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. |
|
| |
|
|
|
|
|
|
|
|
|
|
| |||
| SIP transport |
| User can select UDP or TCP or TLS. Please make sure you’re SIP Server or network |
| ||
|
|
| ||||
|
|
| environment supports SIP over the selected transport method. Default is UDP. |
| ||
|
|
|
|
|
|
|
|
|
|
| |||
| NAT Traversal |
| This parameter defines whether the GXW40XX NAT traversal mechanism is activated or |
| ||
|
|
| ||||
|
|
| not. If activated (by choosing “Yes”) and a STUN server is also specified, then the |
| ||
|
|
| GXW40XX performs according to the STUN client specification. Under this mode, the |
| ||
|
|
| embedded STUN client will detect if and what type of firewall/NAT is being used. If the |
| ||
|
|
| detected NAT is a Full Cone, Restricted Cone, or a |
| ||
|
|
| will 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 GXW40XX |
| ||
|
|
| will periodically (every 20 seconds) send a blank UDP packet (with no payload data) to |
| ||
|
|
| the SIP server to keep the “hole” on the NAT open. |
|
| |
|
|
|
|
|
|
|
|
|
|
| |||
| DNS Mode |
| One from the 3 modes available for “DNS Mode” configuration: |
| ||
|
|
| ||||
|
|
|
| |||
|
|
|
| |||
|
|
|
| |||
|
|
| One mode can be chosen for the client to look up server. |
| ||
|
|
| The default value is “A Record” |
|
| |
|
|
|
|
| ||
|
|
|
|
| ||
|
|
|
| |||
| User ID is Phone |
| If the GXW40XX has an assigned PSTN telephone number, this field should be set to |
| ||
|
| |||||
| Number |
| “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 GXW40XX 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 is cleared on reboot. |
| ||
|
| |||||
|
|
|
|
|
|
|
|
|
|
| |||
| Outgoing Call without |
| Default is No. If set to “Yes,” user can place outgoing calls even when not registered (if |
| ||
|
| |||||
| Registration |
| allowed by Internet Telephone Service Provider) but is unable to receive incoming calls. |
| ||
|
|
| Any port, member of a Hunting Group that is not registered with a SIP account, will be |
| ||
|
|
| able to place outbound calls using the SIP credentials of the primary Hunting Group port. |
| ||
|
|
| For example: Port 1, 3 and 5 are members of the same Hunting Group. Port 1 is |
| ||
|
|
| registered with a SIP account. Ports 3 and 5 are not registered. Ports 3 and 5 will be |
| ||
|
|
| able to place outbound calls using the SIP account of port 1, even if Outgoing Call |
| ||
|
|
| without Registration is set to No |
|
| |
|
|
|
|
|
|
|
|
|
|
| |||
| Register Expiration |
| Allows the user to specify the time frequency (in minutes) for the GXW40XX 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). |
