I understand the purpose of the gatekeepers and the call hand offs between them, etc. What Im looking for is some real world scenarios and how they would work.
Im working on a design that involves six gatekeepers world wide. There will be (6) Callmanager clusters. Im not overly worried about CUCM. i will basically have an access code that send calls to their local designated Gatekeepers.
6 access code to the H323 trunk to the Gatekeeper.
Users will then dial the (3) digit site code and (4) digit extension.
Im assuming the GK will pick up 7 digit number and route to the appropriate GK by zones, etc.
The Gatekeepers are doing the CAC and not CUCM in this design.
Basically, if I have (6) gatekeepers and 6 clusters , calls between the clusters go through the GKs. The GKs hand off the calls to the the CUCM. The CUCM routes to the appropiate MGCP SRST site.
Would this be a correct statement, or do I have something turned around in this "high level" overview?
about it CAC u can do it diffrent ways
but do it simple way as u have multiple GKs
on ur local GK make the CAC base on ur zone and every other zone or all other zones
also u can limit the amount of bandwidth for each call based on ur codec
