Hi, I'm using PJSUA application from pjproject-1.0 on a Mac (Intel). If I set --snd-auto-close=0 (or anything >= 0), then try to make a call, and this call is DISCONNECTED without ever being CONFIRMED or without 180 Ringing from another party, the application won't close sound device. CPU usage will also be relatively high. I've got this result calling any wrong sip address of calling a valid sip address, but hanging up a call before another party answers it. For example, Make call: sip:wrong at sipaddress 16:48:04.050 pjsua_media.c pjsua_set_snd_dev(): attempting to open devices @16000 Hz 16:48:04.562 ec0x2241e0 AEC created, clock_rate=16000, channel=1, samples per frame=320, tail length=200 ms, latency=20 ms 16:48:04.562 pjsua_call.c Making call with acc #1 to sip:wrong at sipaddress 16:48:04.562 pjsua_media.c Media index 0 selected for call 1 16:48:09.576 sound_port.c EC suspended because of inactivity 16:48:12.841 sip_resolve.c Failed to resolve 'sipaddress'.
