Configuring H.323 Gatekeepers and Proxies

H.323 Gatekeeper Configuration Task List

The number of remote gatekeepers multiplied by the delay per LRQ cannot exceed the Routing Information Protocol (RIP) timeout. Therefore, we recommend that you limit your list of remote gatekeepers to two or three.

If LRQ forwarding is enabled on the directory gatekeeper, the sequential setting for LRQs is ignored.

Only E.164 address resolution is supported.

Using redundant H.323 zone support in the “directory gatekeeper” can generate extra RAS messages. Therefore, the number of “directory gatekeeper” levels should be kept to a minimum (two or three at the maximum).
