Re: [Linphone-users] issues using LinPhone

[John White]

Perhaps someone will give you some suggestions.  I too like Linphone and used 
it (sip.diamondcard.us) for many years.  But eventually it just wasn't 
maintained, at least the linux version, so I switched back to twinkle.  I have 
recently been trying linphone again, the appimage version 4.24, and find it 
works a lot of the time, but that it is not very reliable.  Its likely 
something I am doing wrong.  Nonetheless, I generally find twinkle more 
reliable, albeit no video.  It would be nice if linphone had a page that 
described each of the pages in the maintenance section.
