Summary:                    [patch] WaitForSilence never exits - no dsp.conf
Description: 
WaitForSilence to anything other than 1, WaitForSilence never exits

It is a bug in dsp.c. It does not properly init
thresholds[THRESHOLD_SILENCE] 
if the conf file is missing and does not warn if the file is missing.. 

I found that because I did not have a dsp.conf file in /etc/asterisk the
dialplan entry exten => s,1,WaitForSilence(4000,1,60) would be stuck.

Patch to trunk attached...
* Defines a default silence threshold constant set to the current default
of 256
* If the config file is not present, issues a warning saying that it will
use the default silence threshold and applies the default silence
threshold
* Where the variable was set to a static value, i.e. in the event that the
config existed but didn't define the variable or if it was set to an
invalid value, it now uses the constant to apply the default value.
