SOVoIP: True Convergence of Data and Voice Network
Voice Over Internet Protocol (VoIP) is the reality of future telephony provided over the Internet. In the process it is claimed that, voice and data networks are converging into one network. However, such claim only introduced new protocols for telephony on the Internet which are not truly interoperable with existing protocols. Thus we propose a service oriented VoIP architecture, Service Oriented VoIP (SOVoIP), which not only ensures inclusive convergence of Internet and telephony but also ensures Quality of Service (QoS), Enhanced 911 (E911), Communication Assistance for Law Enforcement Act (CALEA), NAT and firewall traversal issue.

Considerations for a Government VoIP Network
While government agencies are not driven by revenue and competition, they are interested in data and voice convergence for real cost reductions as well as supporting enhanced functionality for end users. Convergence allows for only one network to run both voice and data networks, removing the burden of having two separate networks. In addition, converged networks may provide enhanced services such as integrated multimedia messaging including voice, video, email, and fax. But introducing convergence into government networks is not the same as in a carrier network. Strong reliance on satellite links and the support of secure voice are two examples of these differences.

C6X Solutions for a Voice Over IP Gateway
The primary function of a packet voice gateway is to provide the interworking function between traditional voice telephony links and packet network links. For example, an Internet telephony gateway performs a translation between compressed speech packetized in Internet Protocol (IP) and Pulse Code Modulated (PCM) speech over Time Division Multiplexed (TDM) links.
