I don't believe you are heading in the correct direction to resolve this issue. My view is that you have already done what you can to resolve this; however you may be able to achieve a short lived success, but just not something you can fully rely on all the time, i.e. true business class telecom service. My initial thought is that you should contract with a carrier that will deliver your services via MPLS (Multi-Protocol-Label-Switching, this is the platform for carriers to deliver all next generation IP technologies). MPLS will provide you the customer QoS back to the carrier CO and bi-pass the public internet, which is were I believe you are more than likely having your issues. When the carrier delivers an MPLS circuit this allows you to eliminate or reduce any jitter or latency back to the carrier switch. Preferably, you want to have MPLS on both ends, meaning your business and were your VoIP servers reside. This is really the only way to ensure real business class phone service.
