About O1 Communications
O1 Communications is a California-based competitive local exchange carrier (CLEC) founded in 1998, initially focused on providing data telecommunications services to ISPs and later expanding to retail and wholesale business customers. It primarily serves enterprise businesses with voice and data services and wholesale carriers with VoIP peering, call origination, and termination in California and the US. In 2010, it sold its small and medium business customer base to TelePacific Communications; its legacy documents now appear under TPx Communications.
