UCSS), we're building our new infrastructure on 7.X code.<br>

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?<br>

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has it been superceded by something else, i.e. IPIPGW?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><span style='color:black'><o:p></o:p></span></p>
