Adrian Georgescu, Founder and CEO of AG Projects:

"CAIW's move to open standards like SIP and ENUM is an important step for enabling voice, video and interactive messaging via the Internet for its cable subscribers. AG Projects provides the turnkey solution for the SIP residential services and the interconnect with the Dutch SIP-Exchange, which will realize a total PSTN by-pass for SIP sessions between cable operators. By enabling CAIW to use the latest IETF-based standards we witness a major milestone in the migration from Dutch PSTN to Internet real-time communications"

AG Projects 'Multimedia Service Platform' provides a carrier class scalable VoIP platform and includes the most tested individual components of the SIP vendor market. The components are OpenSER, distributed MediaProxy for NAT traversal, CDRTool for accounting, Managed DNS for ENUM routing and NGN-Pro, a SOAP/XML integrated provisioning/accounting engine for all components. OpenSER, a project emerged from FOKUS institute in Berlin, is the most mature SIP Proxy/Registrar solution with more than 4 years of real-life deployments.

AG Projects components complete the signaling core with the necessary front-ends for distributed provisioning, interfaces for accounting, ENUM number translation and NAT traversal.

AG Projects strategy is to help carriers and ITSP's migrate to NGN by providing environments with the same performance and reliability as classic TDM solutions. AG Projects platform addresses the high-availability and redundancy requirements of our target customers. SIP protocol and its extensions have become the natural successor for PSTN signaling protocols.
