Sipek Phone Project
SIPek is a small open source project that is intended to share common VoIP software design concepts and practices. It'd also like to become a simple and easy-to-use SIP phone with many useful features.
SIPek's telephony engine is based on common library used in Sipek project. The telephony part is powered by great SIP stack engine PJSIP (http://www.pjsip.org). The connection between pjsip code (C) and .Net GUI (C#) is handled by simple wrapper which is also suitable for mobile devices. Sipek use C# Audio library from http://www.codeproject.com/KB/graphics/AudioLib.aspx. The SIPek's simple software design enables efficient development, easy upgrading and user menus customizations.
