Minisip fails registering at Asterisk!
Be sure you wrote Asterisk's IP in a numeric format, since Minisip isn't able to resolve addresses yet. Besides, be sure to correctly fill in the SIP URI in the preferences, otherwise it won't work: you'll need a string formed as username@ip, where username MUST be the same as the one in the Registration section, while the ip MUST be the same numeric ip set in the SIP Proxy section. Finally, be sure you correctly added a registration voice for this user in Asterisk's sip.conf configuration file.

How can I know that Minisip is well configured and it can place calls?
Once you've registered at Asterisk, try calling 600. It's an echo test that will help you understanding if your sound card recording functionality is working properly.

When I connect Minisip with Asterisk, I can hear the other people in the conference but the other people can't hear me.
In this version of CONFIANCE all new participants joining a conference will be initially muted by default. Since all available media resources are BFCP-moderated, this means that if you want to talk you need to place a BFCP FloorRequest. Only after you've been granted the floor you'll be able to talk, and other participants in the conference will hear you as well.

How do I enable videoconferences?
First of all, you'll need to opportunely configure Asterisk: to do that, you'll have to enable video in sip.conf configuration file (videosupport=yes). This will enable video support for SIP calls in passthrough mode, i.e. no transcoding. To take advantage of the video support, you'll have to appropriately configure Minisip as well. In the Settings window, choose the right video device on your system (e.g. /dev/video0). Please note that video in Minisip will be enabled only if a webcam is actually active and correctly configured. Once all these steps have been completed, check if everything's fine by placing a call to 600: your own video should be sent back to you, together with your audio.If everything's ok, you'll be able to have videoconferences using CONFIANCE. Just register a new videoconference using one of the available templates and join it. Since Asterisk currently supports video only in passthrough mode, no transcoding and no mixing will be performed. This means that video support in CONFIANCE is limited to a BFCP-moderated videoswitching: participants in the conference will see the video frames sent by the user who's been granted the video floor.
