Expand Your Communications.
Maximize Your Investment.
O1 Communications specializes in delivering high-quality VoIP using SIP trunking to support your growing communications demands and evolving business requirements.

What is SIP?
SIP (Session Initiation Protocol) allows you to gain more control of your communications services and maximize the investment of your PBX business phone system. SIP trunking enables simultaneous calls over a single phone line and also supports Unified Communications options, such as video conferencing. With SIP’s flexibility, it is rapidly becoming business standard. SIP connections are sold per call path, and only one SIP trunk is required to handle all of the simultaneous calls a user wants to make, as long as bandwidth is sufficient. SIP trunks work with Direct Inward Dialing (DID) phone numbers and can use local, out-of-area, and toll-free numbers.
