Being embarrassed by all my requests for new packages, but not having much luck with linphone, I tried to install sflphone, which seems to have some good reviews. I downloaded the rpm and tried rpm2tgz and that didn't work. I tried from source and that didn't work.../configure blew up complaining of a dbus error. I tried vpackager (for the first time) and, though it went a long way and produced a sflphone.SlackBuild, I couldn't get past some kind of a communication or contact error at, I believe, line 127.
So, here I am again, asking for a new package. Twinkle works well, but is cumbersome to use. Linphone 3.6.1, with "subscribe=0" works well but the contacts are hard to use and as it defaults to "subscribe=1" linphonerc has to be corrected periodically so that "subscribe=0." Also video doesn't work on my system. Nonetheless, Linphone is very useful and I use it constantly.
It would be great if VL had a better sip phone in its repositories.
