The Sip:phone - A scalable mobile client for your NGCP platform.

The Sip:phone - A scalable mobile client for your NGCP platform. Sip:phone is not an isolated consumer softphone - it is a completely white-label mobile extension of the Sipwise NGCP platform, designed for operators who want to deliver a seamless voice experience tightly integrated with their SIP/NGCP services. Built on top of the Sipwise Next Generation Communication Platform (NGCP), Sip:phone aligns with the same architecture principles: modularity, operator control, predictable integration with billing and provisioning systems, and full branding flexibility so that it can be offered under your own identity to end customers. Strategic collaboration: Sipwise & DualBit. To accelerate both feature quality and UX polish, Sipwise GmbH work in active development with DualBit, a specialized software partner from Italy experienced in mobile client development for VoIP. This partnership ensures: * Modern, user-centric mobile interfaces * Feature alignment with backend service logic * Faster iterations based on operator feedback * Cross-platform compatibility (iOS & Android) Together, Sipwise GmbH bring a solution that is truly operator-grade, beyond simple off-the-shelf SIP clients. Key platform notes. Just as the Sipwise NGCP is a complete platform and not just a VoIP server, Sip:phone is an extension of that platform - designed to be: * Integrated into your OSS/BSS workflows * Managed with the same provisioning and billing APIs as the rest of NGCP * Operated under the same administrative framework that operators already trust Reach out its Sip:phone product page to have additional information about the app features. Early-Bird launch bundle. For new service launches, Sipwise is offering free branding and store set-up! This offer is only valid through a purchase of the Sip:phone, and for 2026 only. Its Sales team at Sipwise is available to guide you through the complete offering, help assess the right licensing model for your needs, discuss optional modules such as branding, support, or virtualization, and provide pricing and deployment guidance. You can contact them directly via [email protected], or request a personalized consultation to explore how SIP:phone can fit into your existing NGCP environment.
