I am trying to set up a connection between the Linphone Desktop app (using the AppImage from the Linphone website) on my Linux Mint computer and my VOIP service provider
1-VOIP. I used the Account Assistant and Use A SIP Account method to setup the connection. After entering the Username, Password and SIP Domain that I was given by 1-VOIP the connection fails. I see my phone number on the upper left corner of the window next to the search bar and it has a red triangle with an ! mark in it. Can someone help me figure out how to trouble shoot this problem?
