Intelligent Advanced Communications IP Telephony Feasibility for the US Navy - Phase 3

Abstract

The objective of this research paper is to detail our exploration of open source SIP solutions as a viable alternative to building an Assured Services SIP end instrument (aka IP phone) as defined by the DOD Unified Capabilities and requirements specification. This report is based on the following research and validation testing: - L-3 Maritime Systems internal research, - L-3 Maritime Systems VoIP lab research, - L-3 Maritime Systems prototyping of a VoIP Communications Terminal, - Unified Capabilities Requirements 2008 Change 1, - L-3 Maritime Systems Technical Report Intelligent Advanced Communications IP Telephony Feasibility for the US Navy, Volumes 1 and 2 (ISRN L3COM/Maritime Systems/TR-2007/001), - L-3 Maritime Systems Technical Report Intelligent Advanced Communications IP Telephony Feasibility for the US Navy, Phase 2 (ISRN L3COM/Maritime Systems/TR-2009/001), - OSIP, an open source SIP stack, - SipXtapi, an open source SIP stack, - SipXtapi-3.3.0, an open source SIP stack, - REDCOM Slice2100 soft switch with Transip, HDX, - GL Communications VoIP quality test tool, - Wireshark, - Licensing requirements and legal implications of various open source VoIP solutions. The major findings are: - SIP stack behavior and characteristics varies substantially among vendors. - Unlike traditional TDM based phones, SIP stacks and consequently SIP phones are somewhat switch specific in terms of compatibility and vary substantially in terms of what they chose to support. Though one can plug a TDM-based phone into another TDM network and base functionality will work, the same is not true for IP phones. - 2 of the 3 open source SIP stacks we evaluated were maintained outside the United States. - The SipxTapi package in particular has over 13,000 source files; vetting the source for potential malware or any type of security risk would be extremely difficult. None of the open source stacks we surveyed had support for IPV6 fully integrated with the SIP stack. A st
