| − | === Introduction ===
| |
| − | Setting up Trixbox for H323 <-> SIP telephony is not a straightforward procedure. There is basically only one source of information and that is the Trixbox forum. The people on this forum who have a working configuration all integrate a hardware H323 system (like cisco call manager) with the trixbox. We started out trying to directly connect our H323 extensions to the trixbox but this did not seem possible. As a solution we started working with an H323 gatekeeper to handle H323 functionality and let the Trixbox function as gateway. After playing around with the configuration of clients, gk and Trixbox we are able to let H323 -> SIP and SIP -> H323 ring but as soon as it is picked up the call is terminated by the Trixbox. We can handle H323 -> H323 by the just the gatekeeper. At first we thought this might be a codec problem but when we use the same client with SIP there is no problem. Also enabling just one codec on both the SIP and H323 client gives the same problem with no reference to a codec problem in any of the logs.

| | | | |
| − | To have come this far we have had extensive help from one person on the Trixbox forum who has a large H323 and sip network and we followed all his suggestions. What follows is the configuration of Trixbox, GnuGK gatekeeper and different H323 clients as we have it right now. We have intensely studied the output of the asterisk OOH323 and SIP debugger and the gatekeeper logs to figure out what goes wrong with this configuration but they do not show what the problem is. We think that it might be that the gatekeeper does not offer enough functionality to replace the hardware solutions other people have found.

| | | | |
| − | There is another post on the forum by somebody who seems to do it in a different way. If he talking about integrating a network or loose extensions is not clear. We have not had time to investigate his solution. It seems like an awful lot of compiling but it might be worth a try.
| + | '''[[Our Architecture]]''' |
| | | | |
| − | Several people on the forum advise to use trixbox 1.2.3 since they find ooh323 does not work on trixbox 2.0. They also use a very specific version of the asterisk add-ons.
| + | '''[[HOWTO SET UP TRIXBOX AS H323 GATEWAY]]''' |
| | | | |
| − | === Configuration of Trixbox 1.2.3 ===

| − | | |
| − | There are more forums where people say things about h323 but these seem to be the most helpful.
| |
| − | | |
| − | Following the suggestions we used Trixbox 1.2.3 with asterisk-addons-1.2.3. In order to do this we deleted the current addons:
| |
| − | | |
| − | rpm -qa | grep asterisk-addons
| |
| − | rpm -e asterisk-addons-1.2.4_1.2.12.1-1.294
| |
| − | | |
| − | And loaded the older addons: (these can be found ...............)
| |
| − | | |
| − | rpm -i asterisk-addons-1.2.3-1.219.i386.rpm
| |
| − | | |
| − | If this is really necessary we can't tell right now. Once you get everything working it might be worth trying it without these add-ons.

| − | ==== ooh323.conf ====
| |
| − | | |
| − | Next thing was to edit the ooh323.conf file. This file needs to be copied from the samples first:
| |
| − | cp /etc/asterisk-1.2.8-samples/ooh323.conf /etc/asterisk
| |
| − | | |

| − | Comments on this file:
| |
| − | * All parameters that have been changed by us are preceded with a comment line ''';CHANGED'''
| |
| − | * The Trixbox is going to act as gateway for the gatekeeper hence '''gateway = yes'''
| |
| − | * h245tunneling = yes (later our trixbox forum instructor suggested h245tunneling = no, but this did not change anything for us, but this might be an important parameter)
| |
| − | * For some reason it seems that you have to set e164 to the SIP extension number ??? (how to handle multiple extension???) (not true anymore ?)
| |
| − | * We will be using a gatekeeper so '''gatekeeper = 129.125.71.171''' (ip-address of the gatekeeper)
| |
| − | * The user profile section is a bit messy right now and we don't seem to be needing it anyway
| |
| − | | |
| − | ==== Adding H323 extensions ====
| |
| − | | |
| − | A H323 extension can be added in FreePBX as a custom extension. For example:
| |
| − | Extension number: 601
| |
| − | Displayname: Anneke h323
| |
| − | Dial: OOH323/601@129.125.71.172 (ip-address of machine where extension can be found/maybe gatekeeper?)
| |
| − | | |
| − | Asterisk saves these extensions in the file extensions_additional.conf at the ..............
| |
| − | | |
| − | ==== General remarks ====
| |
| − | Whenever you edit anyting in the .conf files makes sure to do
| |
| − | amportal stop
| |
| − | amportal start
| |
| − | | |
| − | at you asterisk prompt. If you then do
| |
| − | asterisk -vvvvr
| |
| − | you get an CLI and here you can type
| |
| − | ooh323 debug
| |
| − | sip debug
| |
| − | exit
| |
| − | to initiate the debugger
| |
| − | | |
| − | === Configuration of Gnomemeeting ===
| |
| − | '''Edit -> Preferences'''
| |
| − | | |
| − | * General: You can fill in your personal data and leave everything default
| |
| − | * H323 Settings: Gatekeeper:
| |
| − | | |
| − | Registering method: Gatekeeper host
| |
| − | Gatekeeper host: 129.125.71.171:1719
| |
| − | Gatekeeper alias: 601
| |
| − |
| |
| − | ''Gatekeeper host'' is the IP address and port of the gatekeeper. Port 1720 is the standard h323 port .
| |
| − | | |
| − | ''Gatekeeper alias'' is the primary alias with the gatekeeper, also the extension number in Asterisk to keep things simple.
| |
| − | | |
| − | Tick the "Register this alias as the primary alias with the gatekeeper" box and Apply (sorry, you need to do this after you've installed the gk) :).
| |
| − | * H323 Settings: Gateway:
| |
| − | ** For H323 to H323 - Do not use a gateway, these calls will only go via the gatekeeper, not the trixbox
| |
| − | ** However for H323 to SIP a gateway to the trixbox (so trixbox ip) is needed but this messes up the h323 to h323 settings. Right now we don't have another solution than manually check or uncheck the box depending on what kind of call you want to make :S
| |
| − | * Codecs: Audio Codecs - We enabled all available codecs.
| |
| − | * Codecs: Video Codecs - We have not been able to spend time on this
| |
| − | * Devices:
| |
| − | ** Audio Devices:
| |
| − | *** Audio Plugin ALSA
| |
| − | *** Output device: Intel ICH5
| |
| − | *** Input device: Intel ICH5
| |
| − | **'''Detect Devices'''
| |
| − | | |
| − | (All the audio and video devices settings are of course depending on your local system, this is more for our own reference) :)
| |
| − | | |
| − | === Alternative: Ekiga ===
| |
| − | To check the codec availability we decided to switch back to Ekiga since it supports SIP and H.323. We first made a SIP call and this worked fine. Switching to H.323 and calling a SIP phone and calling from the SIP phone to Ekiga(H.323) does not report any codec problems. (It seems that this is just a consequence of switching to Ekiga, no other parameters were changed).
| |
| − | | |
| − | === GnuGk Gatekeeper ===
| |
| − | Packages for this gatekeeper are not available for CentOS. We found out that this gatekeeper was already installed in Etch. (System administration provided us with two machines with etch so we could get the sound working).
| |
| − | | |
| − | Almost no configuring here. Just enable PROXY.
| |
| − | | |
| − | Once the gatekeeper is installed you can register your gnomemeeting clients with the gatekeeper (see section '''gnomemeeting'''.
| |
| − | | |
| − | We are still playing with the gatekeeper so this section is under construction.
| |
| − | | |
| − | Suggestions: Proxy, routing
| |
| − | | |
| − | === Progression ===
| |
| − | ==== Using Gnomemeeting ====
| |
| − | * H323 -> H323: via gatekeeper only (gateway unchecked in gnomemeeting preferences)
| |
| − | * H323 -> SIP : rings but no connection can be establihed (gnomemeeting says: no commmon codec). These calls seem to be terminated by the trixbox.
| |
| − | * SIP -> H323 : SIP phone says there is a connection but receiving end gets very short signal followed by the message: call cleared by the gatekeeper. These seem to be terminated by the gatekeeper.
| |
| − | | |
| − | ==== Using Gnomemeeting/Ekiga with GnuGK and TrixBox 1.2.3 ====
| |
| − | * H323 -> H323: via gatekeeper only (gateway unchecked in gnomemeeting preferences)
| |
| − | * H323 -> SIP : rings but no connection can be establihed.
| |
| − | * SIP -> H323 : rings but no connection can be establihed.
| |
| − | | |
| − | We cannot find any errors in the gatekeeper log. The error seems to be in Asterisk. '''Both''' ways the ooh323 debug output says:

| |
| − | This output describes the situation where SIP extension 501 tries to call the H323 extension 602. In this experiment the callee's softphone rings, but after accepting the connection on the softphone, the connection is mysteriously dropped.
| |
| − | | |
| − | Because the telephone do ring, we can conclude that the H323 name resolution part is correctly carried out by the H323 gatekeeper GnuGK.
| |
| − | | |
| − | The next step for a h323 terminal then is to route a connection through the gateway, in this case the h323 channel driver implemented in Asterisk.
| |
| − | | |
| − | By carefully looking at the ooh323c channel driver's output, we notice that for both extensions the data declared in freePBX is found and a connection is set up.
| |
| − | | |
| − | When the called softphone tries to answer, the connection seems to get established; then the sudden hangup seems to originate in the macro-dial but the exact cause is uncertain (''exited non-zero on "SIP/501-0841a378" '').
| |
| − | | |
| − | ==== Using Ekiga with GnuGK and TrixBox 1.2.3 - Update ====
| |
| − |
| |
| − | Another trial was done with almost the same setup: we suspect that the inbound/outbound routes do not play any role when routing calls locally on a Trixbox, even if between SIP and H323.
| |
| − | Moreover, we applied a couple of changes:
| |
| − | | |
| − | 1.in ooh323.conf check;
| |
| − |
| |
| − | h245tunneling=no
| |
| − | faststart=no
| |
| − |
| |
| − | 2.in sip.conf under the line "tos=0x68" check;
| |
| − |
| |
| − | notransfer=yes
| |
| − | canreinvite=no
| |
| − | We also activated both SIP and ooh323c debug messages on Asterisk; unluckily the end result is the very same: the phones ring but the voice connection is dropped when answering. This is the combined debug log:

| − | ==== Common codecs among Ekiga and X-Lite ====
| |
| − |
| |
| − | As recommended on the TrixBox.org fora, we try to limit the codecs set to the common ones. to do so, we register Ekiga as a SIP phone to the TrixBox and make a call; the Ekiga log shows then the following:
| |
| − | | |
| − | 10:07:42 Started Ekiga 2.0.3 for user fabio
| |
| − | 10:07:47 Registered to 129.125.21.241
| |
| − | 10:07:57 Call from Anneke SIP freePBX
| |
| − | 10:07:59 Answering incoming call
| |
| − | 10:08:00 Opened Intel ICH5 for recording with plugin ALSA
| |
| − | 10:08:00 Opened codec PCMU for transmission
| |
| − | 10:08:00 Opened Intel ICH5 for playing with plugin ALSA
| |
| − | 10:08:00 Opened codec PCMU for reception
| |
| − | 10:08:00 Connected with Anneke SIP freePBX using Asterisk PBX
| |
| − | 10:08:10 Closed codec PCMU which was opened for transmission
| |
| − | 10:08:10 Closed codec PCMU which was opened for reception
| |
| − | 10:08:11 Local user cleared the call
| |
| − | The X-Lite unluckily doesn't report any codec information.
| |
| − |
| |
| − | From this log we can conclude that the used codec is the Ekiga's '''PCMU''', which is likely to be X-Lite's '''G711u'''.
| |
| − | | |
| − | ==== Ekiga SIP/H323 capabilities ====
| |
| − | | |
| − | Ekiga is basically gnomemeeting with SIP capabilities added. Ekiga was used at a certain point in order to discover codec-related problems and to conveniently test Asterisk's setup.
| |
| − | | |
| − | At a certain point it was not clear any more which protocols Ekiga was using: removing the gatekeeper parameters made impossible to make any calls (even despite the problem that when the gateway parameter is set, peer-to-peer H323 calls cannot be made any more). Moreover, Once a SIP account is cearted and used, Ekiga starts to listen to all the SIP ports even if the SIP account is disabled.
| |
| − | | |
| − | These and other fuzzy behaviors led us back to gnomemeeting, which can only support H323.
| |
| − | | |
| − | ==== A small experiment with Ohphone -> Asterisk -> X-Lite ====
| |
| − | | |
| − | Inspired by a test found on the ooh323c-devel mailing list, we tried shortly to call a SIP extension of Asterisk by using Ohphone:
| |
| − | | |
| − | As a test first we start the gatekeeper gnugk:
| |
| − | | |
| − | gnugk -ttt
| |
| − | | |
| − | We then start GnomeMeeting on another linux workstation.
| |
| − | | |
| − | On a third linux workstation we dial
| |
| − | ohphone -g 129.125.71.171 -u 601 -e -f -T 602
| |
| − | this succeeds in calling the GnomeMeeting. see the log:
| |
| − | | |
| − | 15:21:28 Started GnomeMeeting 1.2.3 for user fabio
| |
| − | 15:28:58 Gatekeeper set to GNU Gatekeeper@129.125.71.171
| |
| − | 16:31:55 Call from 601
| |
| − | 16:32:03 Answering incoming call
| |
| − | 16:32:03 Opened Intel ICH5 for recording with plugin ALSA
| |
| − | 16:32:03 Opened codec MS-GSM{sw} for transmission
| |
| − | 16:32:03 Connected with 601 using Open H323 Project OhPhone 1.4.5
| |
| − | 16:32:03 Closed codec MS-GSM{sw} which was opened for transmission

| |

| − | Note: Scheduling destruction of call ...
| |
| − | | |
| − | === Conclusion ===
| |
| − | | |
| − | After many trial and error runs and following instructions on the web we have not been able to directly add H323 extensions to the Trixbox. Installing a gatekeeper got us a bit further in the sence that a connection can be established but is destroyed as soon as the ringed extension is picked up. All suggestions on the web come from people with large networks with a hardware H323 solution (Cisco Call manager, Alcatel).
