I ran the following command: pjsua --id sip:number at myims.com --registrar sip:myims.com --proxy sip:SomeIP -realm myims.com --username user --password pass number2 at myims.com<mailto:number2 at myims.com> And I get the error (after successful registration): .Set sound device: capture=-1, playback=-2 In pjsua_aud.c ..Error retrieving default audio device parameters: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV) [status=420006] I have ran the above command with --capture-dev=-1 --playback-dev=-1 but it didn't change anything. Also, I have already installed the package libasound2-dev and fully recompiled the pj files. Every time I have 0 active calls on the "pjsua screen". Does anyone know the solution to this error? -------------- next part -------------- An HTML attachment was scrubbed...
