"With a large call center and four remote offices, our long distance needs are many. TMC monitors our account and contacts me when they see changes in our traffic, just to verify that "all is going as planned." I have one go-to person that can answer all my questions and handle any issues in a turn around time that I have not seen with other carriers. They have even contacted me to tell me they can lower my per-minute costs with my existing account. What other carrier will do that?"
