[Freeswitch-users] Using 16 KHz sounds

[Malay Thakershi]

I don't use Sipura. I use FS to make / receive calls from mobile phones /
regular land line phones.

Unlike what I said in my previous email, I am still using Allison-8kHz
voice. Somehow in managed code I had Allison-16kHz specified.

I created three WAV files using Cepstral SWIFT command with 8000, 16000,
22000 Hz.  When I play each file, the later two give me message at the FS
console "Sample rates don't match".

Is there a setting where I can ask FS to sample at a higher rate that would
help me with sound quality issues? Is having a good sound card on the server
a good practice?

Thank you for replies.

Malay
