Fusion Embedded™ SIP Stack
Embedded Session Initiation Protocol (SIP) Software Stack
The Fusion Embedded™ SIP stack is at the heart of Unicoi's Voice over Internet Protocol (VoIP) offerings, such as InstaVoIP. Fusion Embedded SIP software stack is a lightweight, transport-independent, text-based protocol suite designed for use in IP phones, VoIP gateways, RoIP devices, and other IP-enabled products.
Note: For information on the security-enhanced implementation of Fusion SIP, go to our Fusion SIPS page.
Embedded SIP Software Stack
Fusion Embedded SIP stack source code is specifically designed for use in embedded devices, has a small footprint, and is completely ROMable and re-entrant. The Fusion Embedded SIP stack provides a simplified API for easy integration with the application and transport stack (TCP/IP).
