I'm attempting to get chan_h323 working on Asterisk CVS-STABLE.
I've compiled it ok using the Janus release of pwlib/openh323, by
editing the makefile as per the comments.
Call setup and cleardown seems to work fine, but no audio is being
passed in either direction.
Doing an "h.323 trace 9", I noticed the following sequence at the end
of the call setup:
h323.cxx(1685) H225 Handling PDU: Connect callRef=13295
h323.cxx(1925) H225 Set protocol version to 4
h323.cxx(2152) H225 Set remote party name: "root
[192.168.0.20]"
h323.cxx(2160) H225 Set remote application name: "The NuFone
Network's H.323 Channel Driver for Asterisk 1.0.0 (OpenH323 v1.13.5)
9/61"
h323ep.cxx(1992) H225 Received connect PDU.

h323.cxx(4072) H323 OnSelectLogicalChannels, OpenLogicalChannel failed:
G.711-ALaw-64k{sw} <1>
Why does it want to open /dev/dsp? I'm not trying to play or record using
a local sound device, I just want to pass digital audio between Asterisk
and the network.
The second machine that I am testing this with, trying to get them to talk
to each other, doesn't have any sound hardware, and the third message from
last reads: Could not open sound channel "" for recording:
I assume it is these errors that are preventing audio from being passed.
Can anyone suggest how I might overcome this to make chan_h323 work?
Thanks
Tony
