Extend reach and attractiveness


The Zaark SDK solution is aimed at companies that wish to add free- and low cost call functionality to an existing application. End users are thereby able to make calls directly from the app to fixed- and mobile phones around the world – either via click to call and/or by introducing a dial pad. On request, encryption can be enabled ensuring safe communication which is becoming an increasingly sought after feature at this day in age.

Zaark provides the call engine, server infrastructure as well as the management- and CRM system. The SDK ensures easy integration and comes complete with step-by-step instructions, example code and a pre-packaged communication module. The integration work can either be undertaken by in-house IT resources or with assistance from the Zaark professional services team.

Connection to the fixed- and mobile telephony networks can be facilitated via Zaark’s termination agreements offering low call rates to over 200 destinations. Alternatively you can utilize your own SIP-trunk agreements. Payment functionality can be provided via a separate web-based payment solution or through integration with existing systems.

There are endless examples of apps where communication functionality can be a natural add-on: white pages, dating sites, membership clubs, travel companies etc.
