The Swiss solution for modern Business Messaging, CPaaS and A2P communication

eCall is the versatile Business Messaging and CPaaS platform from Switzerland – designed for companies, organisations and public authorities that want to manage customer communication reliably, securely, automatically and across multiple channels.

Whether SMS, WhatsApp Business API, RCS, email, voice, online fax or a Cloud Contact Centre: eCall combines proven communication technologies with modern digital channels, providing a powerful and future-ready solution for professional business communication.

A key focus is Application-to-Person Messaging, or A2P Messaging. With A2P Messaging, companies send automated messages directly from applications, platforms, CRM systems, ERP solutions, monitoring tools or APIs to customers, employees or business partners. Typical use cases include appointment reminders, login codes, OTP SMS, two-factor authentication, delivery notifications, alerts, outage notifications, service information and opt-in marketing communication.

With eCall, communication processes can be centrally managed, automated and integrated into existing systems – in compliance with GDPR and the Swiss Data Protection Act, and hosted in Switzerland.

All channels – one platform

With eCall, companies can send and receive messages across all major communication channels from a single system. Messages can be sent manually via the web portal or triggered automatically via APIs, gateways and platform integrations.

SMS Service & SMS Gateway:

Send classic text messages via a scalable SMS gateway – automatically via API or manually through the web portal. Ideal for appointment reminders, customer notifications, alerts, OTP codes, two-factor authentication, order information and security-related messages.

Application-to-Person Messaging (A2P):

Send automated messages from software solutions, platforms, applications or business systems to individuals or large recipient groups. This enables recurring communication processes to be handled efficiently, reliably and at scale – from transactional messages to time-critical alerts.

WhatsApp Business API:

Reach customers through one of the most widely used communication channels. With the WhatsApp Business API, companies can implement professional WhatsApp messages, notifications, service dialogues, campaigns, opt-in communication and customer interactions in a secure and structured way.

WhatsApp Marketing and WhatsApp Newsletters:

Communicate through a preferred channel for many customers – with personalised messages, images, buttons and interactive elements. Ideal for offers, news, customer retention, service updates and relevant opt-in marketing communication.

Omnichannel customer communication:

Reach your customers via WhatsApp Business API, SMS, RCS, email and more – centrally, automatically and scalably with eCall, the Swiss CPaaS and A2P Messaging platform.

Omnichannel Customer Support & Service:

Bundle customer enquiries across channels, relieve your teams and automate service processes with WhatsApp Business API, SMS, RCS, email, CPaaS and A2P Messaging.

Rich Communication Services (RCS):

RCS is the modern evolution of SMS and enables richer messages with images, buttons, branding, interactive elements and direct feedback. This makes mobile customer communication more visual, convenient and effective.

Additional channels:

In addition to SMS, WhatsApp Business API and RCS, eCall supports email, voice messages, text-to-speech, online fax and other digital communication channels – all integrated into one central communication system.

CPaaS: flexible integration into existing systems

As a CPaaS solution, eCall enables companies to integrate communication functions into existing applications, processes and workflows. Through APIs and interfaces, messages can be triggered directly from CRM systems, ERP solutions, helpdesk tools, monitoring systems, e-commerce platforms or individual applications.
