Thanks, that's a good find!

I also found solution to another common feature I was planning to add: 
call screening (screening of calls with unknown/missing CID or from 
numbers I don't know or have placed in a special group) - in Asterisk 
this is a bit limited to about 2, 3 options which I have no control 
over, but in FreeSWITCH, it seems, I have a complete freedom of how/what 
to do when call screening is initiated - 
http://wiki.freeswitch.org/wiki/Dialplan_XML (Example 13) is exactly 
what I needed, though I take it I could customise it a bit so that:

I (as the called party) have the option (by pressing a specific key 
after receiving the caller's name) to: 1) accept the call; 2) send a 
message back to the caller saying this number is unavailable and then 
terminate his/her call; 3) redirect him/her to voicemail; 4) drop the 
call entirely without giving any explanation at all (or, alternatively, 
torture them with some moh if they appear to be telemarketing group for 
example). By reading that example, it looks as though this can be achieved.

One other thing: in Asterisk, there is a vast sound library for various 
messages/music/media which could be used. Is there a similar thing in 
FreeSWITCH or should I use Asterisk's media pack for now?

If I use <action application="set" data="RECORD_STEREO=false"/> would 
that be sufficient to record mono instead?
