What Our Clients Think About Us

Enterprise Call Center / High-Volume Operations

Switching to Viber Sip for our contact center was one of the smoothest technical upgrades we’ve made this year. Their smart routing and direct carrier interconnects dramatically improved our Answer-Seizure Ratio (ASR), and our call quality has been crystal clear. The flexible channel capacity allows us to scale up during peak campaign hours without any hitch.

Marcus Vance

VP of Infrastructure & Operations

IT & Telecom Specialist / PBX Integration

As an IT consultant deploying 3CX and Asterisk systems for medium-sized businesses, I need a reliable SIP trunk provider that just works. Viber Sip’s portal makes provisioning DIDs and setting up IP authentication practically instantaneous. Their fraud protection protocols also give our clients total peace of mind.

Global E-Commerce / Global Reach & Virtual DIDs

We needed local phone numbers across 12 countries to establish regional support hubs for our e-commerce brand. Viber Sip allowed us to instantly acquire local DIDs and route inbound calls straight to our web endpoints. Transparent per-second billing with zero hidden fees made tracking our ROI seamless.
