Gareth Bowker is the Director of

Network Security company based in South Wales, who provide secure
Internet
connections, VPNs and Voice-over-IP systems for companies, councils and
charities throughout Wales
and Great Britain.
He has previously worked for British Aerospace,
and he has been
experimenting with VoIP since 2000, specifically using Asterisk
(www.asterisk.org), a GPL software phone exchange. Gareth has to
resist the urge to add ever-more elaborate dialplans to the company
phone
exchange, so that customers are able to speak to a human occasionally.

time, Gareth enjoys hang gliding, skiing
and learning about upcoming technologies. He's occasionally known to
help with
the translation of GNOME into the Welsh language.

This
talk
will give an overview of Voice-over-IP (VoIP), as well as a basic
grounding in
Asterisk, a Free Software VoIP Telephone exchange for Linux.
We
will take a quick tour of the history of
VoIP, the different standards involved and how we got to where we are
today. It
will go into more detail about how to find people using services such
as ENUM
and DUNDi and look at the issues surrounding security and QoS. It will
also cover
the various hardware and software phones that you can use to make and
receive
calls. Lastly, it will cover some typical setups that you might want
and will
give a quick tutorial on how to set up an Asterisk PBX for yourself and
some of
the technologies you might try. |
