There in insufficient information to troubleshoot your issue.  Is this your own gateway or a 3rd party gateway?  If this is your gateway, do you see calls hitting your gateway?  run the command "debug ccsip all" on the gateway to get more debugging info.  Check if you have corresponding POTS dial-peer to terminate the call on the gateway as well.
