8. Problems

8.1. Connection problems

I try to phone to my friend <sip:toto@example.com>, but nothing happens, no ring, nothing at all.

You must verify that linphone uses the network interface that connects you to the internet (or to the network where calls should go). Use the property box, section Network, to select the correct network interface.

In other case, the person you are contacting may be not reachable at the moment...

8.2. Audio problems

Linphone seems to connect to the remote sip url, it rings, but when the callee answers, nothing happens and we can't hear each other.
