AG Projects and Voice System announce the availability of the first integrated NGN communication platform based on SIP protocol. “AG Projects NGN service platform” is a complete solution for carriers and telecom companies offering VoIP services to the residential market. Using the SIP protocol and based on Open Source components, it enters competition with traditional telecom vendors of carrier-class systems.

Easy service creation is one of the highlights of the SIP protocol. It promises a low cost, quick development cycle for applications around SIP. With so much theory on paper and more than two years of live deployments, what can SIP offer today in terms of classic telephony features and value added services?
ENUM is a protocol that provides a translation mechanism for E.164 telephone numbers into IP addressing schemes. Based on standards endorsed by IETF (Internet Engineering Task Force) and ITU (International Telecommunication Union), ENUM is the key ingredient of the convergence between PSTN and Internet.
Traversing NAT (Network Address Translation) is one of the issues that hinder SIP communications. Some background about the problem: With an ideal Internet, all devices would be able to communicate end to end without any intermediaries except routers. This assumes each device has a routable IP address, a public reachable Internet identity. In reality, today many of the devices connected on the Internet are using a NAT function present in the border router. While this stops the Internet to initiate connections to the device (bad for IP telephony or other forms of peer-to-peer communications), it also protects the users against malicious attacks. Using NAT, one may also connect multiple devices to the Internet by only using one public IP address. So NAT has both advantages and disadvantages.
