What is 1ov1 and what does 1ov1 do?

Founded in 2006, 1ov1 is the leading American-based business communication service provider. The company specializes in providing all-in-one managed telecom solutions to businesses, with Voice over Internet Protocol (VoIP) phone systems, phones, and phone lines.

1ov1 differentiates itself by actively managing their customer's systems, which includes making adds, moves, and changes as the customer's business evolves, allowing the customer to focus on their business. 

- 1ov1 was founded in 2006 under the TELESPEX name. 

- 1ov1 is an American provider of cloud-based communication and collaboration services.

- As of 2024, 1ov1 has over 100,000 customers across the US.

- Between 2006 and 2023 the company processed over 5.2 billion calls.

- In the year 2024 TELESPEX rebranded its communications division to 1ov1 and TELESPEX became a holdings company

In addition to mobility, 1ov1 offers advanced and unique features, a higher level of customization, and significant cost savings compared to traditional phone lines and to other VoIP providers.

1ov1 understands that most businesses, no matter their size, do not have resources to plan a full scale  telecom migration. So, 1ov1 provides an account manager who is the customer's dedicated migration planner, and manages the phone number porting, follows up with ongoing programming, maintenance, and support for the life of the account - always for free! You get the phones, and your dedicated account manager takes care of the rest. 

How Does 1ov1 VoIP Service Work?

All phone companies, even cellular companies, use VoIP today. It is a proven and reliable technology. 


VoIP converts your voice (audio) into secure IP data packets and streams them over the internet,  where it's received by the recipient's carrier and converted back to audio. Similar to what your smartphone does when you're using Facetime. IP Phones are mini-computers, and as long as they're connected to the internet they work.

1ov1 Network Requirements

The quality of your existing Internet connection is a factor when establishing consistent and reliable service. VoIP is a live streaming service and thus requires a healthy internet connection to function well. 

The health of your network has everything to do with your call quality. Computer viruses, failing network switches and routers, or degraded internet connections and outages will affect your call quality. So, it's your responsibility to maintain a healthy network for the best audio performance.

As for internet speeds, each VoIP phone requires a reliable 75Kbps (~0.075 Mbps) connection speed. If in doubt, we can perform a simple test to determine if your bandwidth strength can support our technology. Please get in touch with us for a network test.
