[cisco-voip] MGCP gateway not registering to Subscribers

Sorry guys, have been unable to work this further due to other duties.
Bill, unfortunately providing the config of the working gateway is not
going to change anything- both the running-config and the FULL running
configs are nearly exactly the same between the functioning and
nonfunctioning gateways. I compared them line by line and verified the only
differences involve location-specific elements (hostnames, IP addresses,
etc). There were a couple other differences but the differences do not
correlate between other functional/nonfunctional gateways. For example, one
non-registering gateway has h323 bind to G0/0 and one functional gateway
does not. However, I look at another functional gateway and it does have
the command. I have yet to find something that correlates.
I took one of the known working gateways and forced it to register to the
Publisher and all three Subscribers and it did so successfully.
So: configs are idential. IOS rev has been ruled out. Model has been ruled
out. What should I look at next? Could there be switch port config issues
for the routers that are not registering? The debug clearly shows the
gateway and callmanager are communicating but for some reason the
registration is denied on the sub and the router resets to try and register
to the next sub.
Is this a replication issue? I *think* the sites with the gateways unable
to register to the Subs came online after all the ones that are able to
register to Subs. This would make sense, especially because the error code
500 points to "endpoint unknown." So if Publisher replicated the original
gateways and at one point stopped full replication, well there we go. The
question then becomes why can we see ALL the gateways but only some of
their endpoints? If we didn't have fully functional replication, we should
not see any entry. Unless there is a database issue...
Thanks for any insight!
