[Linphone-users] No Linphone playback stream

[chris . gray]

Hi,

I installed linphone 3.6.1 on Debian Stretch (see neofetch output below).
Using the information supplied by my VOIP provider I am able to make a
call to my GSM/mobile/cellphone/händy/whatever, and when I speak into the
headset I can hear myself on the called 'phone, but not vice versa
(although the little VU meter in the Linphone GUI shows a signal). Looking
in PulseAudio Volume Control I can see that a Linphone stream is created
under Recording, but not under Playback. Any idea how to debug this?

The headset I am using is on USB, shows up in PulseAudio Volume Control as
Input Device "USB Audio Device Analog Mono" (mic) and Output Device "USB
Audio Device Analog" (headphones). I am behind my ISP-supplied router,
tried both "specify gateway IP" and "use STUN to resolve" network
settings. Some output from linphonec below.

All hints welcome!
