There are several H323 modules in asterisk. ooh323 comes with asterisk add ons and h323 comes in the asterisk directory. ooh323 has worked better for me how ever it has crashed my server's under heavy usage (IMHO H323 support in asterisk is very poor).

In your configuration you seem to be trying to register to a peer called h323 which does not exist.

Code: Select all
;Contents of H323.conf are
[general]
register => 2222:2222@H323/2222; here 2222:2222 are username and password
register => 2222:2222@00H323/2222
register => 1234:1234@OOH323/1234
register => 1234:1234@H323/1234
register => 1235:1235@OOH323/1235
register => 1235:1235@H323/1235


While I have never tried to register using h323 on asterisk it seems that the statements above are register statements to other servers.

I am not sure the exact settings that ekiga requires (i.e. codecs, faststart etc.) but I use the following code below.

ooh323.conf
Code: Select all
; Objective System's H323 Configuration example for Asterisk
; ooh323c driver configuration
;
; [general] section defines global parameters
;
; This is followed by profiles which can be of three types - user/peer/friend
; Name of the user profile should match with the h323id of the user device.
; For peer/friend profiles, host ip address must be provided as "dynamic" is
; not supported as of now.
;
; Syntax for specifying a H323 device in extensions.conf is
; For Registered peers/friends profiles:
;        OOH323/name where name is the name of the peer/friend profile.
;
; For unregistered H.323 phones:
;        OOH323/ip[:port] OR if gk is used OOH323/alias where alias can be any H323
;                          alias
;
; For dialing into another asterisk peer at a specific exten
;       OOH323/exten/peer OR OOH323/exten@ip
;
; Domain name resolution is not yet supported.
;
; When a H.323 user calls into asterisk, his H323ID is matched with the profile
; name and context is determined to route the call
;
; The channel driver will register all global aliases and aliases defined in
; peer profiles with the gatekeeper, if one exists. So, that when someone
; outside our pbx (non-user) calls an extension, gatekeeper will route that
; call to our asterisk box, from where it will be routed as per dial plan.


[general]
;Define the asetrisk server h323 endpoint

;The port asterisk should listen for incoming H323 connections.
;Default - 1720
port=1720

;The dotted IP address asterisk should listen on for incoming H323

bindaddr=0.0.0.0   

;This parameter indicates whether channel driver should register with
;gatekeeper as a gateway or an endpoint.
;Default - no
gateway=no

;Whether asterisk should use fast-start and tunneling for H323 connections.
;Default - yes
faststart=yes
h245tunneling=yes


;H323-ID to be used for asterisk server
;Default - Asterisk PBX
h323id=ObjSysAsterisk
e164=100

;CallerID to use for calls
;Default - Same as h323id
callerid=asterisk

;Whether this asterisk server will use gatekeeper.
;Default - DISABLE
;gatekeeper = DISCOVER
;gatekeeper = a.b.c.d
gatekeeper = DISABLE

;Location for H323 log file
Default = /var/log/asterisk/h323_log
logfile=/var/log/asterisk/h323_log


;Following values apply to all users/peers/friends defined below, unless
;overridden within their client definition

;Sets default context all clients will be placed in.
;Default - default
context=from-external

;Sets rtptimeout for all clients, unless overridden
;Default - 60 seconds
;rtptimeout=60       ; Terminate call if 60 seconds of no RTP activity
                    ; when we're not on hold

;Type of Service
;Default - none (lowdelay, thoughput, reliability, mincost, none)
;tos=lowdelay

;amaflags = default

;The account code used by default for all clients.
;accountcode=h3230101

;The codecs to be used for all clients.Only ulaw and gsm supported as of now.
;Default - ulaw
; ONLY ulaw, gsm, g729 and g7231 supported as of now
disallow=all     ;Note order of disallow/allow is important.
;allow=ulaw
