CALLTOWER'S GLOBAL PSTN.
Cloud collaboration, UC and Contact Center tools have quickly enabled the new remote and distributed worker environment. However, these powerful “internal” communications tools often have limited access to the “outside” PSTN and call routing integration that enable a complete, cost effective enterprise telephony solution.
Cloud Voice Hub, the evolution of CallTower’s award-winning global SIP trunking service, is purpose-built to solve these challenges. Available in over 70+ countries, Cloud Voice Hub provides certified, secure cloud SIP PSTN connectivity to all major cloud collaboration, unified communications and contact center services including Cisco (Webex Calling and UCM Cloud), Microsoft Teams (Direct Routing), Genesys, Avaya, Zoom and NICE InContact.
