Hello,

I'm trying to find a good tutorial that explains VOIP 'in a
nutshell'.

The textbooks go into too much detail for my purposes. I am
looking for something that someone can read and come away with a basic
understanding of the technical detais of VOIP.

If you have any URLs and could send them my way, I'd really
appreciate it.

Regards,



Fred

Packet structure. That is one hell of a complicated question.

First, you need to decide which VoIP protocol you are interested in.
Viable options are SIP, IAX, H.323 and MGCP, plus a lot of proprietary
protocols usually based on one of those.

SIP is probably the most popular.

If you want to know all the details, then read RFC 3261. Not for the
faint hearted.
http://www.ietf.org/rfc/rfc3261.txt

Also RFC 1889 - RTP - this is how the audio/video data is transmitted

And RFC 2327 - SDP - for describing the RTP sessions.

I've never read that one before. You learn something everyday.

Bookmarked for reading another day.
