About O1 Communications

Our company is built around two core assets: its technology and its people. O1 Communications’ staff is diverse, multidisciplinary, and well educated. As a privately owned company, we encourage an entrepreneurial spirit that helps O1 respond successfully to new opportunities and consistently improve our methods, often resulting in trendsetting telecommunications developments.

O1 Communications was founded in 1998 as a California-based CLEC to provide next generation data telecommunications services to Internet Service Providers (ISPs). O1 quickly became one of the largest dial access providers to ISPs in California. O1 continues to serve wholesale bandwidth and PSTN trunking to telecom service providers today. O1’s SIP services include origination and termination, turnkey VoIP services, and national/international termination. O1 responds to the very specific needs of service providers and CLECs by working with them to design solutions based on their unique requirements. O1 helps VoIP providers create cost-effective peering arrangements with the flexibility to route SIP sessions to a single provider for national termination.
