IP Telephony for Fun and Profit


It is called by various names Voice over IP (VoIP), IP Telephony,
packet telephony. Whatever it is called the underlying foundation is
the Internet Protocol (IP) and its accompanying technologies, packet
switching, for example. As distinct from the old Ma Bell circuit
switched, dedicated circuit approach that was the old way of doing
telephony for most of the 20th century. With an operating system like
Linux and free, open source readily available IP telephony software you
can do amazing things. Hip things to amaze your cool self, and powerful
chores, no less nifty, to provide for eager consumers. Read on,
provisioning, billing systems are deployable today, the possibilities
for growth, the likely pent up demand is real.

We all (or most of us can) understand how IP networks are cobbled
together, and what makes them interoperate. Telephony, for geeks, has
always been a subject of interest, but, tools neccessary to
meaningfully play with it on a larger scale were unavailable until
relatively recently. The advent of open IP-telephony tools and
standards has made the difference.

Tools such as free software PBX'es (AsteriskPBX); or open source
software that provides call control, routing, media, policy, billing
information and provisioning (VOCAL); and GNU's Bayonne project, a
telecommunications application server.

To whet your interest here are a few things you can do, and, or will be
shown how to by Alex Pilosov (NYLUG member), our presenter this July
16th,
* Getting voicemail-over-web
* Voice reader for your email
* Automated attendant
* Follow-me service, discriminating between calls based on Caller-ID
or passwords (e.g., if my wife calls, ring my cell phone---or
perhaps not? maybe your boss is a better bet?)

and other cool things. Of course the standard voicemail needs are also
met with IP telephony, items such as Muzak-like service for call
holders (music on hold, or on transfer, with MP3s, etc.), call
forwarding/tranfering/parking, remore call pick-up, etc. Moreover,
packet telephony can offer facilities such as overhead paging,
multiple-conferences bridging, intercoms tie-ins. On it goes. Piqued?
You'll crave reading some IP telephony books, myriad RFCs by the time
you are done that evening.

Alex will run through:
* The history of telephone networks, from pre-1984 to SS7 to
post-1996 environment, through evolutions in protocols, and
comparisons to similar IP technologies.
* Overview of IP telephony, the various ways to interconnect an IP
network and the public switched telephone network (PSTN). Will
compare current protocols (SIP vs H.323), will layout a brief
overview of Free Software for IP telephony/VoIP.
* An introduction to Asterisk PBX, highlighting the many things you
can do with Asterisk PBX, broadband connection, and VoIP service.

Alex is very knowledgeable and experienced with IP telephony
technologies, as he should be, he uses it in his firm's current litany
of services.

Wednesday July 16 will be this month's meeting date. It will be a treat
to be regaled with such depth of knowledge. Come early, good sitting
will go quickly and be scarce.
