EyeBeam for Android: A Technical Overview of a Mobile SIP Softphone
[Generated for informational purposes] Date: April 14, 2026 Abstract EyeBeam is a legacy Session Initiation Protocol (SIP) softphone developed by CounterPath Corporation, originally designed for desktop operating systems (Windows). While a fully-featured native "EyeBeam for Android" does not exist as a standalone branded product, the technology and protocol implementations that defined EyeBeam have been integrated into CounterPath’s mobile SIP client, Bria . This paper examines the functional equivalent of EyeBeam on the Android platform, detailing its architecture, core VoIP features, security considerations, and practical deployment scenarios. It also addresses the transition from EyeBeam to Bria and the current state of SIP-based softphones on Android. 1. Introduction Voice over IP (VoIP) softphones allow Android devices to place calls over data networks using SIP, a standard signaling protocol. EyeBeam (circa 2005–2010) was one of the most popular desktop SIP clients, known for its wide codec support, presence features, and enterprise interoperability. As mobile usage surpassed desktop, CounterPath shifted focus to Android/iOS clients. While no official "EyeBeam for Android" exists, the Bria Android app inherits EyeBeam's SIP stack, user interface philosophy, and feature set. This paper uses "EyeBeam for Android" to refer to this lineage. 2. Architecture & Protocol Stack The EyeBeam/Bria architecture on Android follows a layered model:
