UNINETT sanntid: A scalable SIP infrastructure for universities and colleges in Norway

TrackTrack 3 (Auditorium 3)
SessionServices
DescriptionUNINETT is in the process of building a SIP infrastructure for the
academic community in Norway. The task is to facilitate and help
colleges and universities to do peer-to-peer communication in compliance
with the SIP standards.
 
A major player in such communication is telephony and naturally much
focus is given to VoIP. The goal is to migrate all colleges and
universities from local ISDN connections to the SIP infrastructure with
a centralized PSTN connection. The process is nearly 40% complete but
already saving the connected institutions money and enabling them to
route calls directly. The migration process also serves as a motivator
for many institutions to modernize their local PBX solution to one that
uses SIP, being a commercial product or self-developed, based on open
source.
 
The talk will describe how the infrastructure is built. It will detail
why and how the use of open standards are important and why SIP and ENUM
are crucial components. Also the talk will show how the open source
platforms, notably KAMAILIO and Asterisk, has enabled us to create
connectors and SIP-enable all the various PBX solutions and platforms we
find amongst our members.
 
Building a SIP infrastructure is much more than setting up SIP proxies.
Opening up telephony to the Internet is often frowned upon due to
security concerns. Much effort has gone into the many layers of security
aimed at protecting from hacking and abuse. The transition to SIP has
also produced befits like the ability to better monitor and log activity
for statistical purposes, which in turn helps create a better service.
 
The talk will show some of the security measures that have been
implemented and some of the tools that have been developed for
monitoring, debugging and management of the infrastructure and its
services. Not having finished the work, there will also be a glimpse
into our future plans for improvement and development of the SIP
infrastructure and it’s supporting systems.
