How does Caller achieve such low international calling rates?

Caller leverages Voice over Internet Protocol (VoIP) technology and direct peering agreements with tier-1 telecommunications carriers and local providers globally. By routing calls over the internet to the nearest point of entry to the destination's public switched telephone network (PSTN), the platform bypasses the traditional, costly international long-distance circuits used by mobile operators. This software-defined network architecture, combined with a high-volume operational model, allows for drastically reduced per-minute costs which are passed directly to the user.

What are the technical requirements to use Caller?

The primary requirement is a stable broadband internet connection. For the application itself, you need a modern web browser (e.g., Chrome, Firefox, Safari, Edge) that supports WebRTC standards, which includes most browsers released within the last 5 years. You will also need a functional microphone and speakers or a headset. No specific hardware, SIM card, or landline is required. The service is accessible from desktop computers, laptops, tablets, and smartphones.

Is call quality reliable and secure?

Yes, Caller utilizes enterprise-grade global infrastructure with multiple points of presence to ensure reliable, low-latency connections. Calls are encoded in high-definition (HD) voice codecs for crystal-clear audio. All call signaling and media streams are secured with bank-level SSL/TLS encryption, ensuring that your conversations are private and protected from interception. Payment transactions are also processed through PCI-compliant systems.

Can I receive calls on a Caller virtual number?

The provided context primarily details Caller's outbound calling functionality from the browser.

Perkoon ensures your files remain private by utilizing peer-to-peer transfers where data never passes through central servers. For cloud storage, files are encrypted on the servers, protecting them from unauthorized access.

Is there a limit to the file size I can send?
