I reported a bug similar to this for Freeswitch 1.4.16 running on Windows:

https://freeswitch.org/jira/browse/FS-7422?filter=-3

It has been fixed in 

FreeSWITCH Version 1.5.15b~64bit ( 64bit)

the one I reported was for raw recording, and there I had some fallouts of 20ms frames because of wrong timer reference.

@Martyn, what do you get if you do raw recording? (latest release makes only sense).

Also, how busy is the server, and is it a physical or virtual machine?

You make no mention of what platform you're running on, I would highly recommend you try 1.4.19, I recall a similar bug already being reported resolved.

After a problem reported by a customer, I've been experimenting with uuid_record from fs_cli to find out where leading silences might be coming from. A couple of files I just recorded had >30s of silence at the start of the wav file that I wasn't expecting.  The experiment goes like this:


1.  I say "one" on the call
2.  uuid_record <uuid> start xx.wav
3.  I say "two" on the call
4.  short pause
5.  I say "three" on the call
6.  uuid_record <uuid> stop xx.wav
7. I say "four" on the call

The resulting xx.wav file contains 33s of silence, "two", pause, "three" end of file. It is silence at the start rather than ambient noise.

The call itself has been up for several minutes now, so I'm not sure where the 30 sec comes from?

The FreeSWITCH version is 1.4.12-1

Regards,
Martyn
