Hi, I'm a bit new in linphone (in facts I discovered it today) and I was glad to find a such good and multi-OS alternative to my X-lite client. I had to find the exact parameters to key in linphone to make it work. It tooks me some times so I decided to write a HOWTO in french with the exemple of the french web provider : FREE.
So if someone of this list need some screeshots and/or some information of the configuration (or make a link on the website to help other french peoples), here is the link : http://simtris.free.fr/blog/?p=354. The article is in CCBY so reuse it.
Hope this can help someone. Cheers -- Simon Guilhot
