1) is it the default behavior that uuid_record record with 2 channels

Yes.

2) is it reasonable that FS can record to 2 channels but cannot
playback?

Could you explain what happens when you play back the files?
Quote:
3) do I need to set RECORD_STEREO=false before uuid_record?

That depends on whether you want two-channel output files or not.

Judging by the error message, it's a known limitation. You are welcome to work
on a fix, or pay the develoeprs to fix it, or offer a bounty that might
encourage someone to work on it, or wait until it gets fixed.

Meanwhile, convert the file to mono and try again.

Sox should be able to do this, for example.

OK let me comment ion this. Your voip connection is a single channel mono. The recording is two channel stereo.. the caller is in the left and the callee is in the right. This is a very helpful tool for call centers when your agent gets into a fight with the caller. FreeSWITCH can not shove a stereo signal down a mono line. Its rather obvious that it has to mux it into one channel... which it does... the other alternative is to just hang up the call and say WOOPS can't do it.
