Voice over IP / IMS stacks
Voice over IP, or more generally multimedia over IP, is the ability to set up interactive messaging, telephony and video conferencing over an IP network. IP Multimedia Subsystem (IMS) is next generation network architecture designed to deliver integrated multimedia services, network convergence, and create an open, standards-based network.
Data Connection provides carrier-grade VoIP signalling and IMS stacks as portable source-code for OEMs developing VoIP/IMS solutions or adding VoIP/IMS capabilities to existing products.
