Field Descriptions:
Number of Responses:
The number of positive responses received from gateway before marking a gateway as "up" (in a reachable state). Drop down menu has selections from 1 and 10 (Default = 3).
Up Timer:
Timer to define the interval the IMG will send the OPTIONS Keep Alive message to the gateway when the gateway is up and responsive. Timer is in seconds (Default=120 seconds) If the gateway does not respond within the timer specifications, the gateway will be marked as down and calls will not be routed to the gateway. The value can be changed by clicking in the field and entering the new value.
Range of Values = 10-600 seconds.
Default value = 120 seconds.
Down Timer:
Timer to define the interval the IMG will send the OPTIONS Keep Alive message to the gateway when the gateway is down (non responsive). If the gateway responds within the timer specifications, and the number of responses indicated happens, the gateway will be marked as up and the routing of calls to the gateway will resume. The value can be changed by clicking in the field and entering the new value.
Range of Values = 1-120 seconds.
Default value = 30 seconds.
200 OK response only:
Disabled (Default)- When property value is set to disabled, the feature is disabled meaning any response will be considered as a valid response and the gateway will be tagged as reachable.
