Configuring H.323

To configure the VCS’s H.323 settings:

•VCS Configuration > Protocols > H.323. You will be taken to the H.323 page.

•xConfiguration H323

H.323 Mode

Determines whether or not the VCS will provide

H.323 gatekeeper functionality.

Registration UDP port

Specifies the port to be used for H.323 UDP registrations.

The default is 1719.

Call signaling TCP port

Specifies the port that listens for H.323 call signaling.

The default is 1720.

Call signaling port range start

Specifies the lower port in the range to be used by H.323 calls once they are established.

The default is 15000.

Call signaling port range end

Specifies the upper port in the range to be used by H.323 calls once they are established.

The default is 19999.

The call signalling port range must be

!great enough to support all the required concurrent calls.

Traversal

Registration conflict mode

Determines how the system will behave if an endpoint attempts to register an alias currently registered from another IP address.

Reject: denies the registration.

Overwrite: deletes the original registration and replaces it with the new registration.

The default is Reject.

Time to live

Specifies the interval (in seconds) at which an H.323 endpoint must re-register with the VCS in order to confirm that it is still functioning.

The default is 1800.

Call time to live

Specifies the interval (in seconds) at which the VCS polls the endpoints in a call to verify that they are still in the call

The default is 120.

Auto discover

Determines whether or not the VCS responds to gatekeeper discovery requests from endpoints.

The default is On.
