Hi,
I am using Fedora 4.11.8-300.fc26.x86_64.
While it is running on a virtual machine hosted on oVirt, I do not think the issue is related to virtualization.
In fact audacity is able to perfectly use the hardware to redirect the speakers and microphone sounds through a spice session.
The pulseaudio and sflphone are as below.
Code:
# dnf list installed pavucontrol* sflphone*
Installed Packages
pavucontrol.x86_64 3.0-8.fc26 @anaconda
sflphone-common.noarch 1.4.1-22.fc26 @dvl-fedora-rhvm-fedora
sflphone-daemon.x86_64 1.4.1-22.fc26 @dvl-fedora-rhvm-fedora
sflphone-gnome.x86_64 1.4.1-22.fc26 @dvl-fedora-rhvm-fedora
sflphone-gnome-plugins.x86_64 1.4.1-22.fc26 @dvl-fedora-rhvm-fedora
Then sflphone is able to register to the SIP server, to initiate a call (I even hear the dialing tone while typing the calling number digits, but not the ringing tone), but when the called answers the phone call, I cannot hear anything nether I am heard.
I can post some logs, if required.
Any help or comment is more than welcome.
