WebRTC is a media and transport engine, there is no signaling part. To cater this we built a connector which translates web requests (using websockets) to SIP requests (and vice versa). Now it is fully working with WebRTC based softphone. Users can make audio or video calls from browsers directly to our mobile and desktop clients. It is important to note that WebRTC to SIP interworking requires certain network elements like STUN/TURN and support for certain audio and video codecs and encryption. We provide all necessary components to make it work not only in client to client (ONNET) scenarios but also to interconnect it with OFFNET elements (breakout gateways, carriers)

They are always offered as whitelabel meaning they are made with a provider’s brand. The branding include logo, name, some changes in the graphics. Also we can modify the skin and flow of the application, such changes are discussed between the customer (provider) and our design team.
We also provide customization in terms of feature set and compatibility with 3rd party systems. For example we made applications for business IP PBX manufacturers (LG Ericson) or to be delivered as a part of some broader service (Orange business PBX). Also we incorporate our dialers in 3rd party apps or integrate our apps with external libraries realizing specific functions.

Are the mobile dialers uploaded under my account on appstore?

What is Rich Communication Suite RCS?

It is a set of requirements that a next generation service should offer. They are based on growing customer expectations which are reaching now far beyond a simple voice calling. Users demand an easy way to share their multimedia with their contacts, make video calls and many more. Also the general trend is that the communication application should be contact oriented which means that on one click on a contact a user can start various interactions. For the application it entails support for certain functionalities like capabilities and user discovery, presence and others. Also the RCS services require backend APIs. Voipswitch provides both applications and the RCS Node which is set of API and mechanism catering for RCS services. It also comprises of a Presence and other application servers (depending on particular deployment). The RCS Node can work with Voipswitch or 3rd party softswitches.
Voipswitch’s RCS Node provides support for RCS services and Voipswitch’s extensions (additional services). We can also provide a solution compliant with GSMA RCS standards

What are DID services?

(DID, also called DDI. In VOIP often called Virtual number) Direct Inward Dialing is a  service that enables customers to be reached directly at their own phone numbers. In VoipSwitch’s realm by DID is understood any phone number associated with a user, without specifying whether the number is  available only from within the system or also from external networks.
