Softphone / Mobile with PortaPhone

Offer new-generation UCaaS using a white-label softphone app for any device via WebRTC

In today’s softphone market...

Many CSPs and MSPs are having trouble competing and monetizing OTT solutions and are in danger of getting left behind.

The biggest vendors and providers of softphones are closing down, slowing development, or becoming direct competitors of smaller CSPs

End-users are choosing new-age OTT services, with features absent from traditional telecom solutions

And they’re losing revenue due to a lack of differentiation in their offers and therefore a lack of monetization

Over The Top (OTT) communication has rapidly become one of the most popular ways for end users to send and receive audio, voice, share files, and collaborate – all while using the Internet.
