Linphone a good working Skype voice over IP alternative

If you never tried linphone I warmly recommend it.
2 days ago, with a friend of mine we tested a bunch of Linux softwares to find out what is the situation with possible alternatives to Skype to transmit Voice and Video. I've been interested into Skype Alternative programs since about 2 years, but so far I never found good and easy to set up working Linux alternative.

We first tried Ekiga. Though it is said to be a good Linux SKype alternative, my ekiga client running on Debian Linux stable Squeeze ver. 3.2.7.2 failed to connect to SIP account I've created on ekiga.net. I've tried hard to make ekiga connect to account SIP created from ekiga.net but all time I was getting an error on connect:

Ekiga did not manage to configure your network settings automatically. You can still use it, but you need to configure your network settings manually.

Please see http://wiki.ekiga.org/index.php/Enable_port_forwarding_manually for instructions

ekiga cant login to SIP protocol error enable port forwarding manually - ekiga is not ready to use on Linux

After continously trying to follow instructions from above pointed URL and making proper settings on my DL-524 Wireless Router and all time ending up with the annoying error, we decided to finally completely abondoned it and try some other voice over IP clients.
We  tried Jitsi and few others which prooved to be unworking. Finally we give a try to Linphone which seemed to be promising. We tested it On Linux platform, where both of Linux installed OS-es where tested were running Debian Linux (one stable Debian Squeeze and one unstable Debian Blackstar). Linphone even with different versions on different Debian Linux OS-es worked fine Video conferences were crashing but voice over IP via SIP protocol works okay.

Setting up linphone to do speak (voice over IP) conference calls with friends is easy task, you need to have linphone package installed, i.e. run:

apt-get install –yes linphone

Then once installed launch it from terminal or GNOME menus with:

$ linphone-3

You will have to create account on linphone.org's website via Register a Linphone account. Once registered and confirmed the account, linphone sends you an email with credential info, through e-mail like:
 

Dear Linphone user, your account has been activated.

You can now use your linphone account with these parameters :

sip:hipo@sip.linphone.org
hipo
sip.linphone.org
 

Regards,
The Linphone team.

Then in linphone you should configure new created Linphone account via:

Linphone -> Preferences -> Manager SIP Account

Once account is added, calls via SIP protocol are ready to go. Probabl,y due to incompitability between versions of Debian stable Linux and unstable the user you will add and about to call is showing as offline, however calling between each other works perfect and voice quality is quite good.

Another great thing about Linphone is it is licensed under free software license GPL2 – meaning source is publicly accessible – thus anyone with skills and desire to port it to any computer architecture can do it. I did not have time to test it throughfully with newer version of linphone to know if Video calls works fine – whether same program versions are used between both peer sides, nevertheless for anyone willing non M$ sniffed channel to do voice calls between Computers linphone is nice.
