We are using redundant callmanagers with 2600s as voice gateways and 7960s for phones. Once and while we get inbound calls where the inbound number is passed as 911 or our local area code. This should be coming in as number unavailable. How can we fix this?

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.
Is this the case?

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:
dial-peer voice 1000 pots
direct-inward-dial
port 1/0:23
!
dial-peer voice 911 pots
destination-pattern 911
direct-inward-dial
port 1/0:23

That worked. Thanks!

Another option is using translation-rules, like this:
Define a translation rule which explicilty uses
no calling number if one is not presented in the ISDN Setup. This should take of the problem your seeing below.
Define a translation rule like the following:
translation-rule 5
Rule 1 null null
Apply the rule to a voice port:
voice-port 1:D
translate calling 5

I'm not sure this works. I believe that the keywords NULL and ANY only work for the "from" part of the translation-rule. I haven't tried this in the latest bleeding edge IOS versions, but you cannot translate TO NULL.
