Registration | Description: This is the timeout interval for | |
Time | registration of the MultiVOIP with a SIP | |
| proxy server. The time interval begins the | |
| moment the MultiVOIP gateway registers | |
| with the SIP proxy server and ends at the | |
| time specified by the user in the Re- | |
| Registration Time field (this field). When/if | |
| registration lapses, call traffic routed to/from | |
| the MultiVOIP through the SIP proxy server | |
| will cease. However, calls in progress will | |
| continue to function until they end. | |

Proxy Polling | integer | The interval between the voip |
Interval | 60 - 300 | gateway’s successive attempts |
|
| to connect to and be governed |
|
| by a higher level SIP proxy |
|
| server. The Primary Proxy is |
|
| the highest level gatekeeper. |
|
| Alternate Proxy 1 is second; |
|
| Alternate Proxy 2 is the lowest |
|
| order SIP proxy server. |
TTL Value | The SIP proxy “Time to Live” value. As soon as a | |
in seconds | MultiVOIP gateway registers with a SIP proxy | |
| server (allowing the proxy server to control its call | |
| traffic) a countdown timer begins. The TTL Value | |
| is the interval of the countdown timer. Before the | |
| TTL countdown expires, the MultiVOIP gateway | |
| needs to register with the gatekeeper in order to | |
| maintain the connection. If the MultiVOIP does | |
| not register before the TTL interval expires, the | |
| MultiVOIP gateway’s registration with the proxy | |
| server will expire and the proxy server will no | |
| longer permit call traffic to or from that gateway. | |
| Calls in progress will continue to function even if | |
| the gateway becomes | |
