Initiation Protocol) is potentially a very disruptive protocol to existing
methods and modes of communication," writes Paul Curto, DETECON, Inc. Senior
Consultant, in SIP Technology: A New Market Enabler, a White Paper newly
released by the innovation and telecom engineering company. The paper is posted
at http://www.deteconusa.com/white_papers.shtml

Some new resources added to The SIP Center
SIPthat.com - Erik Lagerway's daily comments on VoIP, SIP & IP communications.
XTunnels Freeware WIKI
Forum - XTunnels is a solution for Firewall and
Private Proxy traversal for SIP end points. It has been built with one primary
purpose in mind, to allow SIP softphones and videophones to get off the local
firewall without forcing the end user to communicate with network IT managers to
do so or even worse mess with their firewall ports themselves.

voice telephony over the internet and other data networks. Join as a member and
obtain your free UK local-rate telephone number which can be forwarded to any
landline in a number of countries in the World, or your SIP software or hardware

SIP Server Technical Overview
by Amir Zmora, 
SIP Servers are essential network elements that enable SIP endpoints to
exchange messages, register user location, and seamlessly move between networks.
SIP Servers enable network operators to install routing and security policies,
authenticate users and manage user locations.
SIP Server applications may take many forms, but the SIP standard defines
three general types of server functionality that apply to all Proxy, Redirect
and Registrar servers. These standard functionalities can be used according to
the needs of the specific implementation. A SIP Server can also function as a
Presence Server or a Back-to-Back User Agent (B2BUA). In addition, since SIP
defines other event types, such as Winfo and Register, a SIP Server may function
as an Events Server for handling the various SIP events.
With the advance of SIP, server logic has become increasingly complex. SIP
Servers need to deal with varying network topologies (such as public Internet
networks, cellular networks, broadband residential networks), complex routing
policies, security and SIP extensions. SIP Servers often need to handle high
message/transaction rates and yield real-time performance and scalability, high
throughput, and low delay. This chapter discusses the protocol aspects of SIP
Server behavior and the usage of the RADVISION SIP Server Platform to address
the challenges of effective SIP Server development.

The ENUM Forum
We had an excellent response to last months contribution from AG Projects (see ENUM - On its way to
Maturity
). Many thanks to Bob Bownes for letting us know
about the ENUM Forum. I hope this is a useful resource for many of you and if
you know of another resource you would like to see on The SIP Center, please
drop me a line.
The ENUM Forum, organized in 2001, has the mission of establishing industry
standard processes, proceedures, and requirements to implement public and
private instances of an ENUM Domain Name structure within the US and potentially
other countries in the North American Numbering Plan. The ENUM Forum has, in the
past, developed recommendations for implementations and strategies and presented
these recommendations to the US goverment. A Number of ENUM Forum members are,
at the urging of the US goverment, examining the formation of an LLC to move
forward on the implementation of ENUM for the US segment of country code 1.
