Neither. It is sending what it was told to send. If your endpoints are 
particular about receiving consistently-sized frames, then you'll need 
to pad your recording files to an appropriate size. This can be tricky, 
though, since channels can negotiate varying frame sizes, and finding a 
multiple that makes sense for all of them might be more work than you'd 
care to do.

In the end, though, it should not matter: any reasonably well 
implemented endpoint will accept variable-sized frames, as long as they 
aren't any larger than what it has stated its maximum to be (if it did so).
