Simplified Development of SIP User Agent Applications
Session Initiation Protocol SIP has emerged as the standard for VoIP call control and next-generation service creation, supporting interoperability with existing telephony systems and mobility. NMS’s SIP protocol software enables any CG platform or PacketMedia HMP application to interface with SIP proxy servers and other SIP-based servers worldwide. The Natural Access and Natural Access MX development environments' protocol-independent call control API, Natural Call Control, abstracts the low-level details of the SIP protocol, simplifying development and reducing time-to-market for SIP User Agent deployments.
