Configuring H.323 Gatekeepers and Proxies
H.323 Gatekeeper Configuration Task List
VC-303
Cisco IOS Voice, Video, and Fax Configuration Guide
• 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).
