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.
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!
