up to now, I have worked with linphone on my Mint Desktop, that in general worked for me in Version 3.
As I struggle with the "AppImage"s provided for the newer versions, I turned to search for alternatives and found ekiga in version 4 installable using the APT workflow.
But the softphone denies to send the sip registration to my asterisk server.
tcpdump does not show any kind of connection attempt and ekiga just displays “Verarbeitung läuft” => “in progress” o.s.
It has nothing to do with the asterisk configuration. it just does not send any request out of the network interface of the client.
Anybody who knows this behavior and has a solution?
