Are you by any chance using H.323? This problem can happen if the called device (IP phone) is unreachable, and the "huntstop" command is not placed on the last VoIP peer you want searched, it will keep going and more than likely will find the wild card that's set to send calls to the PSTN. This is how the snowball starts and won't stop until all channels are used up. It will also happen if the called party on a remote H323 VGW is busy and you don't have huntstops on the POTS peers on that side. THe call will get kicked back to CCM and will start all over.
