Greetings list,

Just want to confirm will trancoding happen while playing a file having format as below. 

root@debian:/opt/tmp# soxi song.wav

Input File     : 'song.wav'
Channels       : 1
Sample Rate    : 8000
Precision      : 14-bit
Duration       : 00:00:55.05 = 440436 samples ~ 4129.09 CDDA sectors
File Size      : 441k
Bit Rate       : 64.0k
Sample Encoding: 8-bit u-law


If i get PCMU as only codec in invite.

Here .wav is just a container wrapping PCMU audio. 

Best Regards,
