Call Mode

Direct Call Mode

Sets the call mode to direct. In this mode, terminals send ARQ messages to the Gate-

keeper, but pass the call signaling and media control signaling directly between them.

Routed Call Mode

Sets the call mode to routed. In this mode, terminals pass admission requests and call

signaling through the Gatekeeper. Media control information is sent directly between

the terminals.

Note: Though direct calls consume less of the resources of the Gatekeeper, indirect

calls provide better call control.

H.245 Routed Call Mode

Sets the call mode to H.245 routed. In this mode, terminals route all control signaling

through the Gatekeeper and its H.245 Proxy module.

Use Early H.245

Select to cause the H.245 address allocated by the H.245 Proxy to be included in the

outgoing Setup message, allowing H.245 channels to connect before the call is

actually connected.

Configuration Parameters

Maximum Number of Calls

The maximum number of concurrent calls allowed in the zone. This number can be

increased up to 1000, in increments of 20, by purchasing additional concurrent call

licenses.

Maximum Total Bandwidth

The amount of bandwidth in Kbps that call traffic can consume at any given time.

Maximum Bandwidth per Terminal

The maximum amount of bandwidth in Kbps allowed per terminal. This option

applies only to terminals and not to other endpoints, such as gateways or MCUs.

Note: The above three network consumption control parameters are interrelated.

Registration Timeout

Sets the number of hours of inactivity after which the dynamic registration of a

terminal expires. Only the dynamic (online) properties will be unregistered. If the

endpoint is also static (predefined), the static properties remain valid.

IRQ Interval

The interval, in seconds, between IRQ messages sent by the Gatekeeper. IRQ

messages are sent to all online endpoints registered as dynamic in order to verify that

the endpoints are online. The number you set determines the delay between two IRQ

messages to the same endpoint. Choosing the desired delay should take into account

the following factors:
