linphone in Fedora is really, really old. So old in fact that I cannot even determine when 3.6.1 was released. The changelog for the RPM release is: Sun Jul 7 2013 Alexey Kurov <nucleo> - 3.6.1-1 which as you can see is nearly 6 years ago. Surely it's time for an update?
If update needed just uploading of new sources then it was already updated. But unfortunately 4.x branch requires packaging bunch of new packages and I don't have time on working on them. Any help in packaging is welcome. *** This bug has been marked as a duplicate of bug 1116582 ***
