  • Gain without the pain

    Sinch's robust, nationwide all-IP network solution lets you connect to the public switched telephone network (PSTN) without building or maintaining your own telecom ecosystem.

  • Deliver excellence

    Our comprehensive PSTN Connect offers world-class service, diversity, simplicity, and cost savings by eliminating legacy TDM connections — a smart solution for local exchange carriers (LECs), wireless carriers, communication service providers (CSPs), and cable companies.

  • Enjoy unmatched quality and reliability

    Our 100% IP network was designed and built by experts to be the largest and highest quality on-net footprint in the U.S. — and the fact it isn't pieced together with multiple providers means you’ll avoid backbone outages.

  • Rely on the industry leader

    Sinch is the biggest provider of PSTN Connect service, with many wireless, LEC, cable, and CSP customers. Plus, we completed the largest and most successful nationwide implementation for two of the country's largest wireless carriers!

  • Get support for all call types

    Sinch provides transport for all inbound local and long distance calls, including toll-free and delivers voice traffic to you via diverse SIP connections, with support for outbound local and long distance routing.
