Siperb

Siperb is a modern softphone powered by WebRTC, paired with a hosted WebRTC-to-SIP proxy that connects it to your existing PBX. Rather than replacing your phone system, Siperb bridges it: if your Asterisk or FreeSWITCH PBX isn't WebRTC-ready, Siperb's proxy handles the protocol translation, NAT traversal, and media negotiation so your team can make and receive calls from a browser, mobile app, or desktop client - no hardware, no forced migration. The softphone client runs on Web, Windows, macOS, Linux, Android, and iOS, with call recording (audio & video), blind and attended call transfer, 3-way conferencing, and end-to-end encrypted media. On the proxy side, Siperb supports inbound and outbound SIP registration, register-less connections, mobile and web push notifications, and DTLS-to-RTP media transcoding for PBXs that don't natively support WebRTC's encrypted media format. A free Personal tier covers the hosted proxy and softphone clients for individuals and small setups. Business (£2/domain user/month) adds message and call recording storage/sync, custom integrations, and multi-user domain management. Business Pro (£5/domain user/month) adds extended storage, call transcoding, and upcoming AI agent features. Core client and proxy code is open source (AGPL-3.0) on GitHub for teams who want to self-host.

Smartz Solutions

Smartz Solutions is the disruptor reshaping the contact center landscape. Traditional legacy systems, with their entangled infrastructures and exorbitant fees, have held businesses hostage for too long. Contact centers are tired of being burdened by disjointed systems with hefty price tags and bad customer and employee experiences. We’re redefining the contact centre experience through our AI-powered 360-degree experience platform. We’ve been there. We paid for the legacy systems. We had 15 different systems running (at a snail's pace) at once to be able to run our call centre. We know the pain of not being able to find data quickly enough (sometimes at all) to help customers. And we sure know what it’s like to have employee information in multiple systems; never showing a clear view of the business. Losing money, opportunities and patience doesn’t have to be how you continue to run your call centre. Through a comprehensive tech stack, you will finally have your entire customer and employee experience in one place with the data and insights to make strategic decisions in real time.
