Shenandoah Telecommunications Selects TNS Call Guardian For Robocall Detection

Sponsored by Businesswire

Transaction Network Services (TNS) today announced that Shenandoah Telecommunications Company (“Shentel”) (Nasdaq:SHEN) – a leading provider of fiber-optic services in the Mid-Atlantic region – has chosen TNS Call Guardian for its robocall mitigation services, continuing a nearly three-decade partnership between the two companies.

Americans received a staggering 77 billion unwanted robocalls in 2020, frustrating subscribers and leading carriers of all sizes to adopt robocall detection tools and technologies to authenticate calls from unknown numbers. As revealed in TNS’ 2021 Robocall Investigation Report, 37% of calls placed to wireline telephone numbers are unwanted, compared to 17% of calls to wireless numbers, impacting regional carriers that want to provide quality service to their subscribers.

TNS Call Guardian is an industry-leading call analytics solution uniquely capable of addressing the robocall threat by analyzing over 1 billion daily call events. As a result, TNS Call Guardian enables carriers to more accurately identify spoofed robocalls.

“It’s becoming increasingly vital that all carriers deploy a reliable solution for call analytics to address and solve the negative impact of robocalls on consumers and businesses alike,” said TNS’ CEO Mike Keegan. “We’re thrilled Shentel has chosen TNS Call Guardian – the most accurate reputation profile solution available – making them one of the first regional telecom providers to take this step.”

Shentel – a TNS network signaling and database routing customer since 1993 – selected TNS Call Guardian as its robocall detection solution based on the companies’ long-standing relationship, TNS’ flexible network integration that provides a quick and economical go-to-market solution and TNS’ superior analytics capabilities. In order to align with the FCC’s mandate for carriers to implement a STIR/SHAKEN-compliant call authentication solution, Shentel will also onboard TNS’ Call Guardian Authentication Hub – a managed end-to-end call authentication solution that analyzes real-time call events combined with STIR/SHAKEN authentication and validation of caller ID – in a phased approach.

“Robocalls are more than just a nuisance to our customers; they can have more serious implications if a bad actor gets ahold of personal information and/or money,” said Shentel’s Matt Krueger, Vice President Product Management. “When we decided to pursue a robocall detection solution, we looked no further than our partner of almost three decades, TNS, whose dedication to their carrier partners helps us fulfill our promise to our subscribers.”
