The History of OpenCNAM

  • 2011

    OpenCNAM is Born In 2011, the first RESTful Caller ID API was introduced featuring CNAM from the databases that housed carrier supplied CNAM values in North America. Back in 2011, the need for a modern API that delivering Caller ID to the new world of engineers working with HTTP and SIP protocols was clear.

  • OpenCNAM gains support from the developer community and becomes a staple for many open source projects such as FreePBX.

  • Development of Version 2 begins with the goal of offering a real-time network CNAM by directly querying the authoritative storage providers for each carrier through a paid OpenCNAM service level.

  • 2012

    Version 2 Launched With the launch of V2 in 2012, OpenCNAM begins to gain praise from several high-profile influencers in the tech world such as David Weekly, a former Google product leader.

  • 2013

    More Popularity Within the Open Source Community Several more open source integrations surface. Open source developers begin to built OpenCNAM into projects like CyanogenMod, and build libraries, wrappers, and plugins for a wide variety of programming frameworks.

  • 2014

    Telo is Formed In late 2014 Telo was formed by Chris Brunner and Brent James, partner in the company that founded OpenCNAM. The focus at Telo was build telco-rooted data products that made life easy for engineers and provided a clear value-add for companies.

  • Telo recruits and adds talented core team members and consultants to build out its vision of the company and products.

  • 2015

    Development of Version 3 Begins Work on V3 begins with a goal of making OpenCNAM an international carrier-grade service in terms of latency, accuracy, reliability, compatibility and support.

  • The vision of creating the first international carrier-grade Caller ID API begins to become a reality as carrier relationships are formed and data partners are carefully analyzed and selected.

  • 2016

    Version 3 is Launched In early 2016, after a year of product development, Telo unveils OpenCNAM V3. The third generation of OpenCNAM boasts the Plus service level, which brings name coverage in the +1 dialing plan up to approximately 87% and offers 57% coverage across more than 200 countries world-wide.

  • The launch also features new interfaces support for telephone carrier technologies including SS7, SIGTRAN, ENUM, and SIP alongside the original RESTful API. These new interfaces and OpenCNAM's account flexibility now make managing mixed networks easy.

  • Telo begins engaging platform experts to publish official integration guides. Platforms such as Broadsoft, Sonus, Metaswitch, Asterisk, FreeSwitch, FreePBX, and many others now come complete with guides and support to make integration simple.

  • As Telo continues to make things easier for carriers, the original modern RESTful API continues to gain popularity amongst the programming landscape. OpenCNAM is featured on ProductHunt exposing it to a wider range of developers.
