I have contracted with Optidial for many years and on different projects (IT infrastructure/long distance/VOIP) and have always found I can reduce costs and improve reliability every single time. I work with multinationals and the requirements can be tricky. Optidial has always come through with cross border VPNs and VOIPs. He can also deliver US phone numbers in Mexico. etc. I would highly recommend Optidial to any business that wants to improve their telecom services.
