Bug#442414: zaptel-source: When ztdummy module is loaded ztest hangs and asterisk playback doesn't work

[Chris Nestrud]

Package: zaptel-source
Version: 1:1.4.5.1~dfsg-1
Severity: important


This concerns the following programs:
kernel 2.6.22-2-686 
Zaptel modules compiled for this kernel
from zaptel-source Version 1:1.4.5.1~dfsg-1
Asterisk version 1:1.4.11~dfsg-1

if the ztdummy module is loaded, the asterisk playback() command
will not play files. DTMF is still properly received. If the ztdummy
module is unloaded, sound playback works again.

The "zttest" command hangs and provides no output when the ztdummy module is loaded.

I have the following modules loaded:
