So in your CCS trace you see your dial out. The record with have "RO" in it.
For the incoming record it will have a "RI" in it. (If you call from your cell phone will not have to worry about seeing the "RO" record.
Are you seeing the "RI"?
If not, call your carrier.
If yes, check for number conflicts.
Then check to be sure your COS, call rerouting, tenant, interconnect restrictions are all set the same.
If you don't see anything then it may be easier to call the carrier and ask them what they see when you call in.
