Bug#272259: asterisk: No sound when using H.323 channel

[Hendrik Weimer]

Package: asterisk
Version: 1:0.9.1+1.0RC1-8
Severity: normal

When connecting to asterisk with an H.323 client there is no sound being
sent on the channel. If I call the demo voice menu, asterisk says that
the message is being played, but there is no subsequent traffic on the
network:

-- Executing BackGround("H323/ip$212.9.189.172:30005/29597",
"demo-congrats") in new stack
-- Playing 'demo-congrats' (language 'en')

If I use gnomemeeting as the client, it reports something about a codec
that is closed immediately after the connection is established:

12:05:56 Opened codec G.711-ALaw-64k{sw} for transmission
12:05:56 Connected with root  using The NuFone Network's H.323 Channel
Driver for Asterisk	1.0.0 
12:05:56 Closed codec G.711-ALaw-64k{sw} which was opened for
transmission

Enforcing different codecs in h323.conf lead to the same results.
Version 1.0-1 from testing does not show this problem.
