are matching the current channel sampling frequency and codec. For<br>
example, if you record a G722 call, you would get a 16kHZ WAV file.<br>
<br>
Forcing it into one specific encoding would add real-time CPU load. I<br>
think it's still more preferable to run a post-processing job in low<br>
priority -- this way you ensure that the ongoing calls get the best<br>
serving.<br>
<br>
You can easily catch the event of call ending and trigger the<br>
conversion job, by listening to the events via ESL connection.<br>
