I do not think the call manager would be getting the call unless you have an voip dial peer on the gateway which points at the call manager and has a destination of 9T or .T or something to this effect.
Yes, the reason you are seeing 911 as the caller ID for some calls is that when the telco does not send you a caller ID for a call for whatever reason, the router uses the destination-pattern of the originating dial-peer which in this case is 911. This can be worked around by putting another dial-peer in the configuration file before this one that has no destination-pattern. The configuration would look like this:
