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

[Lelio Fulgenzi]

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 Is gatekeeper still a relevant technology or has it been superceded by something else, i.e. IPIPGW?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