Ok in prior versions up to 1.0-rc1 if you set the --null_audio option you could do sip without audio hardware present. With this version I get this error: DEBUG: pa_dev.c Sound device count=0 DEBUG: pa_dev.c PortAudio sound library shutting down.. TRACE: pa_dev.c PA message: TerminateHostApis in TRACE: pa_dev.c PA message: TerminateHostApis out DEBUG: wmme_dev.c WMME found no sound devices ERROR: pjsua_media.c Media stack initialization has returned error: Found no audio devices (PJMEDIA_EAUD_NODEV) [status=420005] I am using the 1.1 zip file on the download page. Any ideas? Thanks, David Clark ps. I was successful in setting up FFT analysis of frequency data on a given call in real time. Let me know if anybody is interested in how this is done. I did it using a memory capture port so zero mods to the pjsip library where done.
