Feature Comparison
Caller
Browser-Based WebRTC Calling
Caller's core technology is built on the WebRTC framework, allowing users to initiate and receive voice calls directly from their web browser without any plugins or downloads. This ensures maximum compatibility across devices and operating systems, from laptops to tablets. The architecture leverages secure peer-to-peer-like connections optimized by global media servers, ensuring low-latency, high-definition audio that bypasses the limitations and costs of traditional Public Switched Telephone Network (PSTN) routing.
Transparent Pay-As-You-Go Billing
The platform operates on a pure usage-based billing model with no monthly subscriptions, contracts, or hidden fees. Users pre-pay for credits that never expire and are charged only for completed call minutes at published rates starting from $0.02 per minute. This financial model, powered by a real-time billing API, provides complete cost control and transparency, making it ideal for variable usage patterns and for businesses looking to optimize communication expenses with precise, auditable spending.
Global Number Provisioning API
Beyond outbound calling, Caller offers an API-driven service for provisioning dedicated virtual phone numbers in countries like the US and UK. Users can acquire local, toll-free, or mobile numbers to use as a professional caller ID or for establishing a business presence. This feature integrates seamlessly with the core calling stack, enabling instant activation and management of numbers directly from the user dashboard for use in outbound communication strategies.
Enterprise-Grade Security & Encryption
All communication on the Caller platform is secured with bank-level SSL/TLS 1.2+ encryption, ensuring that both signaling (call setup) and media (audio streams) are protected from interception. This end-to-end security model safeguards sensitive business conversations and payment transactions. The platform's infrastructure is designed with privacy-by-design principles, requiring no personal phone verification for outbound calls, which enhances user anonymity and simplifies onboarding.

Frequently Asked Questions
Caller FAQ
What technology does Caller use for browser-based calling?
Caller is built on the standardized WebRTC (Web Real-Time Communication) API, which is natively supported by all major modern browsers. This technology handles the real-time capture and encoding of audio directly in the browser, establishes a secure peer-to-peer connection (facilitated by STUN/TURN servers for network traversal), and manages the streaming of high-definition voice data over UDP for optimal performance and low latency, eliminating the need for any external software.
Do I need a phone number or SIM card to use Caller?
No, you do not need a personal phone number or SIM card to make outbound calls with Caller. You simply sign up with an email address, add credits, and start calling. Your caller ID can be set to a private number or to a dedicated virtual number purchased through Caller's number provisioning service. This makes it ideal for privacy and for users who want a separate business line.
How does the pay-as-you-go credit system work?
You pre-purchase credits into your Caller account wallet via secure payment methods. These credits have no expiration date. When you make a call, the platform's billing system deducts credits in real-time based on the per-minute rate of the destination country and the exact duration of the connected call. You only pay for completed minutes, and you can track your remaining balance and usage history in your account dashboard at any time.
Can I use Caller on my mobile device?
Yes, Caller is fully functional on mobile devices. Because it is a web application built on WebRTC, it works within the mobile web browsers (like Safari on iOS or Chrome on Android) on smartphones and tablets. There is no native app to download from an app store; you simply navigate to the Caller website, log in, and the calling interface will be optimized for your mobile screen, providing the same features and call quality.
