Enterprise CPaaS Platform

Telnxo — Voice, SMS,
and Messaging on One API

Telnxo is a cloud communication platform by Rackwave Technologies — providing programmable voice, SMS, and WhatsApp messaging through a single API, along with a cloud contact centre for support and sales teams that need reliable telephony without managing on-premise hardware.

Programmable Voice SMS & WhatsApp API Cloud Contact Centre Developer-First API
Overview

Communication Infrastructure Without the Hardware

Telnxo replaces on-premise PBX systems and disconnected messaging tools with a single cloud platform for voice calls, SMS, and WhatsApp — accessible through a developer-friendly API for teams building communication into their own products, and through a ready-to-use contact centre interface for support and sales teams that just need to make and take calls reliably.

Rackwave Technologies implements Telnxo for businesses replacing legacy telephony, building click-to-call and notification features into their own applications, or standing up a cloud contact centre from scratch.

As a CPaaS (Communications Platform as a Service), Telnxo sits in the same category as Twilio and Vonage — a business messaging platform that gives enterprises programmable voice, SMS, and WhatsApp without building or maintaining telephony infrastructure themselves.

FAQ

Frequently Asked Questions

Everything you need to know about Telnxo.

  • What is Telnxo?

    Telnxo is a cloud communication platform developed by Rackwave Technologies, providing programmable voice, SMS, and WhatsApp messaging through a single API, along with a ready-to-use cloud contact centre interface. It's built for both developers integrating communication into their own products and support or sales teams that need reliable telephony without on-premise hardware.

  • What is CPaaS?

    CPaaS (Communications Platform as a Service) is a cloud category that lets businesses add voice, SMS, and messaging capability into their own applications through an API, rather than building telephony infrastructure from scratch or licensing separate hardware-based systems. Telnxo is Rackwave's CPaaS offering — the same category as providers like Twilio or Vonage, positioned as a business messaging platform for enterprises that want communication infrastructure without managing it themselves.

  • Can Telnxo replace our existing office phone system?

    Yes. Telnxo's cloud contact centre replaces traditional on-premise PBX systems with call queuing, skill-based routing, and supervisor monitoring accessible through a web interface — no phone hardware or IT infrastructure required beyond an internet connection. Number porting from your existing provider is handled as part of implementation.

  • Does Telnxo support WhatsApp Business messaging?

    Yes. Telnxo includes WhatsApp Business API access for sending transactional messages, notifications, and supporting two-way customer conversations, alongside standard SMS — both accessible through the same API and reporting dashboard as voice.

  • Can developers build directly on Telnxo's API?

    Yes. Telnxo provides a REST API for programmable voice and messaging, with webhook-based event notifications for call and message status, and SDKs for common programming languages. Rackwave also provides hands-on integration support for teams building Telnxo into an existing CRM, helpdesk, or internal application rather than just handing over API documentation.

  • Is call recording available, and is it compliant for regulated industries?

    Yes. Telnxo supports automatic call recording with searchable transcription and configurable data retention policies by call type or department, suitable for quality assurance, training, and compliance requirements in regulated industries such as financial services and healthcare.

  • How do we get started with Telnxo?

    Getting started begins with a demonstration and requirements discussion covering your current telephony setup, call volume, integration needs, and whether you need the contact centre interface, the API, or both. We then provide a proposal with implementation scope, number porting plan, timeline, and pricing. Contact us via the form above or connect on WhatsApp to schedule your Telnxo demonstration.
