I have a computer that I want to make out-going calls from. it is a virtual machine and has no microphone/speakers (as it's a command line server). I'm using pjsua to connect to our asterisk server, so specifying: ./pjsua --null-audio --id=sip:user at ip --registrar=sip:server --realm=* --username=user --password=pass sip:phone#@server makes the calls very nicely, but of course I get no sound. I wanted to make a phone call by specifying a wav file to play, but without null-audio I get errors like: 08:58:07.733 pjsua_media.c Error retrieving default audio device parameters: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [status=420006] How does one go about using pjsua on a computer with no audio devices? -Isaac -------------- next part -------------- An HTML attachment was scrubbed...
