Distributel, COMsolve and NetNumber Establish a Trial Program of a STIR/SHAKEN solution

COMsolve Inc., a leading-edge Information and Communications Technology (ICT) solution provider, is pleased to announce a trial of a STIR/SHAKEN solution designed for Canadian Competitive Local Exchange Carriers (CLECs).

Toronto, ON – July 20, 2021COMsolve today announces the commencement of a technology trial with Distributel and NetNumber to provide a complete solution for CLECs to cost-effectively provide caller ID authentication and verification measures. This involves a complete solution for the signing and verification of known trusted calls, ensuring that their legitimate subscribers' calls are processed inside the STIR/SHAKEN trusted network.

North American consumers receive over 200,000 unwanted and/or fraudulent calls every minute, many using spoofed caller IDs to increase the likelihood that the called party will answer the call. To combat this growing problem, the Canadian Radio-television and Communications Commission (CRTC) has mandated service provider implementation of the STIR/SHAKEN set of standards as a solution to the widespread use of caller ID spoofing in fraudulent calls. Service Providers operating IP-based voice services must implement STIR/SHAKEN in their networks by November 30, 2021.

Through this trial, Distributel, together with COMsolve and NetNumber, is testing a secure cloud-based solution for call signing and verification using NetNumber’s Guaranteed Caller™ Service Provider and Guaranteed Caller Cloud Connect products to provide STIR/SHAKEN attestations associated with calling ID. This service enables CLECs to quickly and efficiently deploy a STIR/SHAKEN solution to meet the CRTC’s deadline.

Rishi Bahall, Vice President of Network Services says, "Distributel is pleased to work with COMsolve and NetNumber to trial a STIR/SHAKEN solution for the CLEC market in Canada. We always aim to provide the best experience for our customers and this will position us to deploy a quick and cost-effective solution to reduce the impact of caller ID spoofing on our customers."

“We are delighted to work with Distributel to bring NetNumber’s leading-edge Guaranteed Callerä solutions to the Canadian market,” says Ofir Smadja, Founder and CEO of COMsolve. “With our deep understanding of STIR/SHAKEN requirements for Canada, we are uniquely positioned to bring Guaranteed Callerä to the Canadian market, and offer these unparalleled solutions to carriers, TSP and enterprises.”

“We are excited to have been chosen to participate in this STIR/SHAKEN trial with Distributel and our partner, COMsolve”, says Matt Rosenberg, Chief Revenue Officer, NetNumber. “The need to provide cost effective and innovative solutions to manage the growing number of fraudulent calls, through spoofing of caller IDs, is a critical first step in ensuring a secure and trusted network. We look forward to working with them to make this STIR/SHAKEN trial for Canadian Competitive Local Exchange Carriers, a success.”
