You haven't adequately described your full inbound call path. Please post the complete details. For example, which number are people calling, a GV number, or a CC number. If it's a GV number, is that number now provisioned directly on SP2, or is the GV number being forwarded through CC? I hope you are not trying to use both methods, one on SP1 and one on SP2.
There is no way we can magically understand your setup unless you explain the issue in more detail; as-is, it makes no sense.
