Hi,

Does anybody know how I can turn on the logging for H323 in Asterisk? I have
set the logging path and the file name in the ooh323.conf file however it
did not help. The file is created but is empty. I want to, if possible, turn
on the logging in DEBUG level.

The file name is ooh323c.conf (note the extra 'c').

It is used by chan_ooh323c, rather than chan_h323. chan_ooh323c is
unmaintained and not recommended for new installations.

This was because until recently, the most up-to-date chan_ooh323 driver
and stack were the ones in the 1.2 branch of asterisk-addons.

However, I recently ported the 1.2 version forward to 1.4, trunk and
1.6.0, and added a couple of bug fixes. Those changes were accepted into
SVN, so that all those variants are now up to date. It should therefore
now be easy to keep them maintained as far as Asterisk API changes are
concerned.

Having tried chan_h323, chan_oh323 and chan_ooh323, I *would* strongly
recommend chan_ooh323 over the first two. It is clean and lightweight,
uses the Asterisk RTP stack (and can therefore bridge properly), and
doesn't creak under the bloat of OpenH323 like the first two do.

I don't know whether Objective Systems have abandoned chan_ooh323 and
the ooh323c stack, but it would be great to see them moved from -addons
into the main Asterisk tree.

I am still looking to know if all of these h323's are
able to work as gatekeeper, so endpoint can register?

About "chan_ooh323 and using It is clean the Asterisk
RTP stack (and can therefore bridge properly), and
doesn't creak under the bloat of OpenH323 like the
first two do":

The other two: how they use the RTP stack if they do
not use Asterisk RTP?

And what do u mean by bridge properly? (How?)

Your kindly help is high appreciated.

I think they all run only as a gateway, not a gatekeeper, but I'm not
100% certain.

Looking at http://www.voip-info.org/wiki/index.php?page=Asterisk+H323+channels
it appears I was only partially correct. I never got chan_h323 working,
so have less experience of that. According to the above wiki page,
chan_h323 does use the Asterisk RTP stack, although it still uses the
OpenH323 library for the protocol part.

I used chan_oh323 for a long time 2 or 3 years ago, and it definitely
didn't use Asterisk's RTP stack, nor its codecs. It used the ones that
are part of OpenH323, and communicated with the chan_oh323 driver using
pipes (I guess in slin format). It was very profligate in its use of
system resources (file descriptors, CPU, etc), such that even on a dual
Xeon system we got degradation above about 15 simultaneous calls.

With both those versions, you easily run into version number hell with
OpenH323 and PWlib, which is another reason, IMHO, to avoid them.

I tried chan_ooh323 much more recently, and it just felt cleaner, more
streamlined and better integrated with Asterisk. However, I have not yet
used it in production. When I need to, this is the H.323 driver that I
will use, and if necessary bug fix and/or enhance.

Quote:

I guess since chan_h323 does indeed use Asterisk RTP, that it can bridge
channels at the RTP packet level just like chan_ooh323 and chan_sip can.
But chan_oh323 always had to pass audio through the Asterisk core because
it didn't use Asterisk RTP.

Hi Sema,

Thanks a lot for the tips. I have turned on the logging and saw them in the
console. However, this applies only for startup, when I try to register a
user, which I cannot succeed, there is no logging done.

Check your logger.conf file and make sure that verbose is going either to
messages, or full or both. Then you will be able to extract relevant debug
output for any future posting.

Quote:

Do you think you can give me an idea why my user cannot register? All I want
to do is, send the register to a GK which has the IWF functionality.

I haven't enough information to answer that, and I am not very familiar
with gatekeepers anyway.

Quote:

Attached I am sending my extensions.conf and ooh323.conf files.

A few things I noticed:

In your extensions.conf, you have this:

[h323]
exten => _1NXXNXXXXXX,1,Dial,H323/${EXTEN}

When using chan_ooh323, you need to use OOH323 instead of H323, and you
also need to name the peer you want to dial out through:

exten => _1NXXNXXXXXX,1,Dial(OOH323/${EXTEN}@mypeer1)

Or possibly "Sema" instead of "mypeer1", depending on what you need.

In your ooh323.conf, you should disallow all codecs first, and then just
allow the ones you want. For initial testing, just stick with ulaw or alaw:

disallow=all
allow=ulaw
allow=alaw

Then remove the "allow=all" from your peer, user and friend sections.

There may well be other issues, but fix these first. Then if you still
get problems, include the verbose output from the log file.

Cheers
Tony

This was always the plan from the beginning.

I have a post from one of the Objective Systems developers:

"We are working closely with digium towards making it an official
channel driver once the testing phase is complete."

I'm not sure what happened subsequently - perhaps licencing issues, but
I agree, it is an easy to build implementation that I have had in light
production use for 3 years.

Hi Richard,

I could not succeed to make my ooh323 work somehow. I can see the peers
and the users but although my exten definition states that the call
should be forwarded to a GK, Asterisk does not send it out. I also have
the same problem with registration.

Do you think you can give me some ideas? Maybe send your conf as a
reference?

I am sorry I have no experience using ooh323 with a gatekeeper.

My setup is as an endpoint between asterisk and a Panasonic TDM100 PBX.
