ContactPoint IP Phone review
A focused, open-source Windows SIP client with useful desktop calling tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ContactPoint IP Phone is a lightweight, open-source SIP softphone for Windows. It connects to SIP accounts and registrars, including Asterisk-based systems, and supports both 32-bit and 64-bit Windows. The core feature set covers SIP calling, a contacts book, call logs, hotkeys, operating-system-native click-to-call, incoming-call browser triggers, and advanced SIP headers for call centers. It is aimed at individuals and teams that want a focused desktop SIP client rather than a broad communications suite.
Its strongest fit is the combination of practical desktop controls and extensibility. Contacts and call logs cover everyday calling workflows, while hotkeys and native click-to-call can connect calling to existing Windows habits. The customizable plugin architecture gives technical teams a way to adapt the client, and Asterisk integration supports deployments built around that platform. Advanced SIP headers also make the product relevant to specific call-center workflows that depend on SIP-level control.
The trade-off is a narrow product scope. ContactPoint IP Phone is centered on Windows desktop SIP calling, so it suits buyers who already have SIP accounts or registrars and want a compact client for that environment. Teams seeking a wider communications platform should look elsewhere if they need broader platform coverage or capabilities beyond this SIP-focused desktop model. Choose ContactPoint IP Phone when open-source availability, Windows support, and configurable SIP behavior matter most; avoid it when the priority is an expansive multi-platform communications stack.
