<p class="MsoNormal"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">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.<br>
<br>
Do I use a gatekeeper for this? Is gatekeeper still a relevant technology or
has it been superceded by something else, i.e. IPIPGW?<br>
<br>
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? </span></p>
<ul type="disc">
<li class="MsoNormal" style="color: black;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">Can I get away with only one zone?</span></li>
<li class="MsoNormal" style="color: black;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">Can I configure two gatekeepers in some sort of
redunant mode?</span></li>
<li class="MsoNormal" style="color: black;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif";">Can a gatekeeper assist with COR lists in anyway?</span></li>
</ul>
<p class="MsoNormal" style="margin-bottom: 12pt;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">Hopefully someone can point me
in the right direction....<br>
