asterisk users - Aug 2003 - Gatekeeper

Hello

I am a newbie to Asterisk. We have set up Asterisk on a PC with Redhat 9.0. We
have installed H323 openphone on our PC's. We are wondering what a
gatekeeper does. It seems we need one but what I have seen in this group is that
a gatekeeper must be installed on another box on the network. As all our
PC's on the network use Microsoft OS is there a free gatekeeper software for
microsoft operating system?

Does Asterisk have a built in gatekeeper? 

Many thanks
Wayne

Asterisk does not included a gatekeeper but you can download a one from
http://www.openh323.org <http://www.openh323.org> 
 
As for whether or not you NEED gatekeeper, probably not.  If you have a
gatekeeper you can register your h323 endpoints (openphone) with the
gatekeeper, then have asterisk register with the gatekeeper.  Only the phone
numbers with the prefix specified in h323.conf would get routed from the
gatekeeper to asterisk, otherwise the gatekeeper would handle all of the
routing, but asterisk can do all of that.
 
If I were in a relatively small office (where a map of phone numbers to ip
addresses are easy to keep track of) I probably wouldn't bother with a
gatekeeper.

I've setup an asterisk server H.323 compliant, with a GnuGk gatekeeper.

My h323.conf is:

[General]
port=1720
gatekeeper=127.0.0.1
context=default

[PABX]
type=H323
e164=PABX
prefix=0
context=default

my gatekeeper.ini contain:

[RasSrv::GWPrefixes]
PABX=0

When i call, from a gatekeeper registered endpoint a number with prefix
0 the call is forwarded to asterisk, but asterisk send the call in
extension s, how send the call to (prefix)NUMBER to extension NUMBER ???

Thanks,
Igor
