[cisco-voip] gatekeepers - when, why, how?

[Lelio Fulgenzi]

Thanks Chris. Unfortunately we do not have access to 8.X code (no UCSS), we're building our new infrastructure on 7.X code. 

That being said, if I were to want to use this just during SRST times and all my devices were running the appropriate IOS code, could I get away with it?

Hi Lelio, 



You may want to investigate using the new Service Advertisement Framework and Call Control Discovery that are included in the new 8.0 release. It can be more distributed and is much simpler than a gatekeeper deployment.

So, taking off from a previous discussion about requiring MGCP enabled endpoints to support SG3 speeds, I was thinking, how do I get all these devices to talk to each other during SRST/H323 fallback. I could configure a whole bunch of dial-peers, but that doesn't sound like fun with ports assigned with non-consecutive extension ranges. 

Do I use a gatekeeper for this? Is gatekeeper still a relevant technology or has it been superceded by something else, i.e. IPIPGW? 

Assuming I have a stack of 8 x VG224s and 8 x 2901s (w/ VIC3-2FXS-E/DID for long distances) and 2 x 3945s (to hold all the SCCP registrations) what would be the recommended approach? 

    • Can I get away with only one zone? 
    • Can I configure two gatekeepers in some sort of redunant mode? 
    • Can a gatekeeper assist with COR lists in anyway? 


Hopefully someone can point me in the right direction....
