I have been using this variable record_post_process_exec_app in my dialplan for post-processing of recordings where I actually convert the WAV files into an MP3 using Lame. I earlier used to record it in mp3 directly using the mod_shout module, but it was very CPU extensive. I wish to do the same for calls that are recorded using the mod_callcenter module. In callcenter groups, I can define record_template, but I dont find a place where I can do post record processing.
One way I figured to do this, was in the dialplan do this:
<action application="set" data="record_post_process_exec_app=system:lame file.wav file.mp3"/>
<action application="set" data="cc_export_vars=record_post_process_exec_app"/>
<action application="callcenter" data="group1"/>
The above works but the challenge is when you want the agent name in the recording filename; because there is no way the agent name is known while we are in the dialplan. Basically the record template in groups is defined as follows:
<param name="record-template" value="/recordings/${strftime(%Y%m%d%H%M%S)}_${caller_id_number}_${cc_agent}.mp3"/>
Can we also have a record-post-parameter config parameter for callcenter module calls.
Thanks for any suggestions in getting this done using a different approach !!
