Short summary




United Kingdom


2017 – ongoing

Metaswitch (a Microsoft Company) is one of the most persistent telco software vendors on the market, and the world’s leading cloud-native communications software company. They support more than 1,000 service providers globally, including tier-1 operators such as Sprint, AT&T, Verizon, Orange, Telmex, and AIS.

The challenge

Working with Metaswitch was an honour, but it did come with its fair share of challenges.

Mobile communications are getting unified, blending the native dialer of the smartphone with network-based voice and messaging services, multiple personas, groups, etc.; overtopping the OTT apps’ experience (features).

Real-time communication applications are highly demanding in performance, usability, and feature richness, requiring expert domain and platform knowledge which DECODE has accumulated over the years.

The solution

By working closely with Metaswitch’s in-house engineers and exchanging knowledge and expertise on both sides, we were able to develop several apps with rich communications features and an unprecedented user experience.

Usability, seamlessness, and cross-device support are what consumers are looking for, and we know how to deliver it.

How we set up our team and tools when we start working with a software company

This blog will describe which tools, processes, and practices we use here at DECODE, and how we approach new projects.

Working with DECODE is a pleasure. Their expertise on iOS and Android is excellent and as well as working well with my team they’ve also presented workshops on mobile development to help train up my less experienced engineers.

The superb UX and quality of service we achieve in implementing video/audio calls & conferencing, rich instant messaging, content sharing, presence, group collaboration, and similar aspects on multiple devices (phones, tablets), allows us to cater to the most demanding customers.

Since realizing this ambitious project for Metaswitch, DECODE has become not only one of their key suppliers, but a trusted partner in the field of app development.

DECODE has built a reputation within Metaswitch as supplying quality code at the exacting standards we expect of our own developers.
