This code was recently updated to deal with Open H.323 v1.14.4 and PWLib
|
|
|
|
|
v1.7.5. Not much testing has been done, please test and report your findings.
|
|
|
|
|
|
|
|
|
|
This code runs on Open H.323 v1.12.2 and PWLib v1.5.2. If you use different
|
|
|
|
|
versions, you are on your own. See the Makefile for more details.
|
|
|
|
|
|
|
|
|
|
chan_h323 has been implemented using Asterisk's RTP stack insted of trying
|
|
|
|
|
to implement a pseudo sound card driver. I feel this is more effiecent,
|
|
|
|
|
due to the Asterisk.
|
|
|
|
|
You can find the Open H.323 source here: http://www.sf.net/projects/openh323/
|
|
|
|
|
|
|
|
|
|
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.

|
To compile this code:
|
|
|
|
|
Once PWLib and Open H.323 have been compiled per their specific build instructions, issue
|
|
|
|
|
a make in the asterisk/channels/h323 directory, then go back to the Asterisk source
|
|
|
|
|
top level directory and issue a make install.

Upgrading Asterisk
|
|

-----------------

|
|
After you cvs update (or make update) Asterisk you have to go into

asterisk/channels/h323 and issue a make clean all, before compiling the
|
|
|
|

rest of asterisk. Doing this process every time you upgrade Asterisk

Dialing an H.323 channel
|
|
|
|
|
|
|
|
|
|
Note: At the present time chan_h323 does not support dialing with a type=peer.
|
|
|
|
|
|
|
|
|
|
------------------------
|
|
|
|
|
Without a gatekeeper:
|
|
|
|
|
|
|
|
|
|
exten => _1NXXNXXXXXX,1,Dial,H323/${EXTEN}@ip.address.or.hostname/callerid
|
|
|
|
|
exten => _1NXXNXXXXXX,1,Dial,H323/${EXTEN}@peer
|
|
|
|
|
or
|
|
|
|
|
exten => _1NXXNXXXXXX,1,Dial,H323/${EXTEN}@ip.or.hostname
|
|
|
|
|
|
|
|
|
|
Using a gatekeeper:
|
|
|
|
|
|
|
|
|
|
exten => _1NXXNXXXXXX,1,Dial,H323/${EXTEN}
|
|
|
|
|
|
|
|
|
|
The 'callerid' is optional. If omitted the callerid will be determined by
|
|
|
|
|
any type=h323 stanzas in h323.conf
|
|
|
|
|
Notice: When using a gatekeeper you cannot utilize the type=peer features,
|
|
|
|
|
since the H.323 spec states that when a Gatekeeper is part of an H.323 network,
|
|
|
|
|
the Gatekeeper shall be used for all communication.

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' or worst case

senerio 'h.323 trace 4'.
