IVR Gateway is receiving "False Calls"

We are implementing a IVR system across our network, and have over 30 sites converted and in Production. One office is giving us problems in the fact that after they close for the day, their IVR gateway starts receiving calls that appear to have a real caller behind them. Every couple seconds, the IVR will pick up a call, start running through it's default script, and treat the call as a "Rotary Phone Transfer" when it doesn't receive any response from the caller. Logs state that we receive over 5000 of these "Rotary Phone Transfer" calls for this one office between 5:00 pm & 8:00 am every night.

I need help with how to figure out if our IVR is the source of the problem or their PBX.

Re: IVR Gateway is receiving "False Calls"

The most common problems with IVR include:

The application is not properly configured on the plain old telephone service (POTS) dial-peer.

Make sure that the incoming Telephony call matches the POTS dial-peer with the application. The POTS dial-peer matches the first dial-peer with the matching port command in the configuration or if the called number matches the dial-peer subcommand incoming called-number .

Check that the application actually exists through the show call application voice summary command. Make sure that the application name does not contain a syntax error.

Make sure that direct-inward-dial is not configured on the dial-peer pots.

Ensure that the proper audio files are loaded into Flash.

Ensure that the authentication with username and password is properly configured.
