For those who use FreeSwitch for commercial purposes in the US - did you have to buy any license to use LAME?
Need to translate from .wav to .mo3 to play the recording. Do I need to worry? WinLAME README:

“Note that personal and/or commercial use of compiled versions of the LAME encoding engine (including the DLL distributed with winLAME) requires a   patent license in some countries. Check before using winLAME!”

Thanks,
A.C.
