[Freeswitch-users] Wideband Skype to SIP?

I read the SVOPC Wikipedia page and it does say it's sampled at 16khz indeed.
I do encourage you to try to make a regular Skype call to echo123 and then try the same routed through FS. The quality is substantially different and I do think the audio bandwidth remains higher on a Skype to Skype call.
Since the support for FS is done through an emulation driver, it would be good to try different encoding settings to confirm.

It might also be the version of Skype that is running that could be limited at L16 / 16khz. The newer version do support Sylk.

Best,
Emrah
