Greetings, I am looking for who everyone considers to be the best Tier-1 provider of wholesale TF inbound SIP services. We are currently using Level(3) and can't get them to generate a valid batch of CDRs for reconciliation if their life depended on it. The voice quality is fine as are the call setups, but the CDR problem is huge for us. We are doing about 5mm/mo of inbound TF and have about 20K TF numbers. Thanks. Geoff
