[GnomeMeeting-list] FAQ

[Damien Sandras <dsandras seconix com>]

Rafaël, thanks for your answers and the useful links that you sent to
the mailing list. It is true that H.323 is a very complicated protocols
and the real H.323 gurus are the Equivalence guys who created OpenH323.

I would suggest to add those questions to the FAQ :
What is a Gatekeeper and what does it do?
This component of H.323 manages the bandwidth inbound
and outbound from the LAN. Gatekeepers register clients and coordinate
communications with other gatekeepers. There are four features in a
Gatekeeper: 
Admission control authorizes clients' access to the LAN.
Bandwidth control for each network segment managed.
Client network addresses are translated so those participants
can dial network locations with aliases (such as e-mail addresses)
instead
of IP addresses.
Call management monitors H.323 calls, tracks rejected calls,
accounts for use of WAN links and monitors other H.323 Components.

What is H.245 Tunneling?
This is the encapsulation of H.245 messages within H.225/Q.931 messages
(H.245 tunneling). If you have a firewall and enable H.245 Tunneling,
there is one less TCP port that you need to allow for incoming
connections.

What is fast start?
Fast Connect is a new method of call setup that bypasses some usual
steps in order to make it faster. In addition to the speed improvement,
Fast Connect allows the media channels to be operational before the
CONNECT message is sent, which is a requirement for certain billing
procedures. It was introduced in OpenH323 version2.
