[Asterisk-Users] H.323 Audio problem UPDATE

[Scott Stingel]

Hi-

In answer to your questions:

Someone on Friday had said that disabling Fast Start corrected the audio
problem with H.323, so yesterday I tried to disable it in
~/asterisk/channels/h323/ast_h323.cpp.  Today, I noticed that Jeremy
(NuFone) uploaded a new version of this file with the same fix:

Change the line:
BOOL	noFastStart;
To:
BOOL	noFastStart = TRUE; 

Unfortunately, this made no difference for connections from my customer's
Cisco 5300, so I decided to abandon the built-in h323 in favour of oh323.
Maybe you'll have better luck with the original code.

I don't have the option of going back to the so-called STABLE version, since
there are now many fixes and updates in the current HEAD that effect me.

Anyway, so far I'm happy with Michael Manousos' oh323 drivers.  Here's the
full link:

http://www.inaccessnetworks.com/projects/asterisk-oh323

Suggest that you try it and see if it works for you, if you have any
problems with the built-in h323 code. The web site provides a lot of info
about versions and what is supported.

I'm running the latest oh323 0.6.2a, which requires PWLib 1.6.6 and OpenH323
1.13.5.  Don't use any other versions of these - might not work

Regards
Scott

Hi, Scott. Are you telling me that this "native" h.323 has been hardcoded
with fast start? Can you tell me where in ast_h323.cpp it is that you
disabled this faststart? Have you tried using the Stable cvs of the
Asterisk.

Can you let me know which version of the OH323 are you using ? Is it the
0.6.2A? Which version of the Pwlib and OpenH323 you used, is it the newest
version as stated? Did you apply the patch? I tried using this driver, but I
have problem with cdr_mysql, it is not recording cdr. Please share your
information, thanks alot.

Update on this problem:

I gave up on  the "native" h.323 because, like others, I couldn't get audio
working.  (yes, I tried disabling FastStart in ast_h323.cpp - no change)

So I went and got the OH323 code from www.inaccessnetworks.com.  Glad to say
that everything seems to work so far.  Not only does audio work, but even
the handshaking is now working in both OpenPhone and even NetMeeting (for
the first time).

Notes to others who want to try OH323:

* The installation is a bit more complicated than h323.  Follow the
instructions in the ReadMe file exactly.

* You must choose and install the proper versions of PWLib and OpenH323, as
stated.

* Don't forget to edit the Makefile as stated.

Some load testing to following this week, but I'm encouraged!

Regards
Scott
