NethVoice new voice recording has a "click" when recording is started

[Stell0]

There is an audible "click" when a recording is started. This is because of the file extension and format: file extension is ".sln" but file format is ".wav".

• Renaming the file in ".wav" resolve the issue.
• Converting files to .sln (RAW, 8KHz) also solve the issue and should be better for performance

Steps to reproduce

• call echotest (*43)
• you can hear the click before recording starts
• now rename file in .wav mv /var/lib/asterisk/sounds/en/demo-echotest.sln /var/lib/asterisk/sounds/en/demo-echotest.wav
• click should disappear
• now convert file in raw sox /var/lib/asterisk/sounds/en/demo-echotest.wav -t raw -r 8000 /var/lib/asterisk/sounds/en/demo-echotest.sln; mv /var/lib/asterisk/sounds/en/demo-echotest.wav /var/lib/asterisk/sounds/en/demo-echotest.wav.bak
• issue should also be solved

Test case:

• only nethvoice-lang-en and nethvoice-lang-it requires testing
• verify that "click" in recording is no more present
• make sure that recordings can be listened using extensions with different common codecs
