Open H.323 Channel Driver for Asterisk
|
|
By Jeremy McNamara
|
|
For The NuFone Network
|
|
|
|
First public release on November 10th, 2002
|
|
|
|
|
|
Developed using: RedHat 7.2/7.3/8.0
|
|
Open H.323 v1.11.7
|
|
PWLib v1.4.11
|
|
GCC 2.96/3.1
|
|
|
|
Dependancies: openssl-0.9.6b
|
|
openssl-devel-0.9.6b
|
|
expat-1.95
|
|
expat-dev-1.95
|
|
|
|
We have implemented this driver using Asterisk's RTP stack insted of trying
|
|
to implement a pseudo sound card driver.
|
|
|
|
NOTICE: Whatever you do, DO NOT USE distrubution specific installs
|
|
of Open H.323 and PWLib. In fact you should check to make sure
|
|
your distro didn't install them for you without your knowledge.
|
|
Check everything out of CVS. If you dont know how to deal with cvs, learn.
|
|
Also, if you are not using the listed versions of Open H.323 or PWlib
|
|
you are on your own, sorry.
|
|
|
|
Warning: Older versions than listed will NOT work, but newer versions
|
|
~should~ work but are untested and you would be on your own.
|
|
|
|
As of June 16th, 2003 the release version of Open H.323 does not compile
|
|
due to the G729Capability is missing. If you want G.729 support see
|
|
the Makefile.
|
|
|
|
Some chan_h323 users have reported success and others have reported dramatic
|
|
failures when using newer versions of Open H.323. We haven't personally tested
|
|
this and will not be able to assist you if you have 'issues'. Sorry.
|
|
|
|
IN OTHER WORDS: Run Open H.323 v1.11.7 nothing newer nothing older if u want
|
|
this to work.
|
|
|
|
|
|
To compile this code:
|
|
Issue a make in the asterisk/channels/h323 directory, then go back to the Asterisk
|
|
source top level directory and issue a make install.
|
|
|
|
|
|
|
|
Most common compile error:
|
|
|
|
If you receive anything that says 'undefined symbol' you are experiencing
|
|
typical version skew. For example:
|
|
|
|
libh323_linux_x86_r.so.1: undefined symbol: GetNumberValueAt__C14PAbstractArrayi
|
|
|
|
You need to search and destroy every version of libh323 and libpt then
|
|
completely recompile everything
|
|
|
|
Example commands to make sure everything gets cleaned and then
|
|
rebult in proper order:
|
|
|
|
cd /path/to/pwlib
|
|
make clean opt
|
|
cd /path/to/openh323
|
|
make clean opt
|
|
cd asterisk/channels/h323
|
|
make clean install
|
|
|
|
(Note: Open H.323 or PWLib never get a 'make install' so don't do it)
|
|
|
|
|
|
Most common run-time error:
|
|
|
|
libpt_linux_x86_r.so.1: cannot open shared object file: No such
|
|
file or directory
|
|
|
|
You have not set the LD_LIBRARY_PATH environment variable.
|
|
|
|
Example environment for sh/bash:
|
|
|
|
PWLIBDIR=$HOME/pwlib
|
|
export PWLIBDIR
|
|
OPENH323DIR=$HOME/openh323
|
|
export OPENH323DIR
|
|
LD_LIBRARY_PATH=$PWLIBDIR/lib:$OPENH323DIR/lib
|
|
export LD_LIBRARY_PATH
|
|
|
|
We recomend puting the above directives into your /etc/profile so
|
|
you do not have to remember to export those values every time you
|
|
want to recompile.
|
|
|
|
|
|
If you still have trouble please contact 'JerJer' in #Asterisk on
|
|
irc.freenode.net or send and email to jj@nufone.net
|
|
|
|
If you happen to be lucky enough to segfault this code please run a
|
|
backtrace and send me the gory details. Segmentation faults are not
|
|
tolerated, no matter what Distro you run!
|
|
|
|
bt example:
|
|
|
|
# /usr/sbin/asterisk -vvvgc
|
|
...
|
|
[chan_h323.so]
|
|
Segmentation Fault (core dumped)
|
|
|
|
# ls core.*
|
|
core.1976
|
|
|
|
# gdb /usr/sbin/asterisk core.1976
|
|
...lots of useless garbage here..
|
|
(gdb) bt
|
|
|
|
Send whatever shows up right after the 'bt'
|
|
|
|
|
|
Also, a full debug screen output is almost needed. Make sure you are
|
|
in the full console mode (-c) and turn on 'h.323 debug'. A nice way
|
|
to capture everything is to use the utility called 'script' (man script)
