Are you running it on a VPS without an audio device or on a Desktop computer?

Asking because the first testing and uses has been done on a computer with an audio device, so i'm wondering if it isn't needed to setup a virtual-dummy sound device?

If is that the case, I'd look to
https://stackoverflow.com/questions/16483635/pjsip-new-call-error-unable-to-find-default-audio-device-pjmedia-eaud-nodef
and
modprobe snd-dummy enable=1 index=5 id="dummy"

Yes i download and install on VPS can you please guide me virtual-dummy sound device setup ?
as i am not good in Linux.

thank you in advance.
