Linphone "open souce voip project"

You just downloaded Linphone on your iPhone, Android or Windows Phone 8. Great ! But what happens now ? What's that complicated settings view?
Let's go to the basics: before being able to place calls to any number worldwide, you need to purchase a SIP account from a VoIP operator or you can use our free SIP service. The VoIP operator's role is to transform a pure internet VoIP call into classical PSTN call, thanks to a set of machines called gateways.
Linphone is a general purpose SIP softphone that isn't bound to any operator. Because it is compatible with SIP, it can work with any VoIP operator using SIP (most of them use SIP, the most notable exception being Skype). Linphone.org is not affiliated nor recommends a VoIP operator in particular. We invite you to select a VoIP provider in your country by browsing the web, and compare rates etc…
Note that you might have a SIP account included with your internet line subscription: it is the case in France for clients of the free.fr internet provider, who is powering the freephonie.net VoIP network.
Ok I have now a SIP account at some-voip-company dot com, what do I do?
Go to the settings page of Linphone. On android it is accessible through the "menu" button, on iPhone the settings are located within the Settings application, together with all other iPhone settings. You'll have to enter at least three things:
  • Username
  • Domain
  • Password
All this information should be provided to you by your VoIP operator during signup process. For your information, username and domain form your SIP identity when grouped together like an email address:
sip:my_username@my_voip_provider
Sometimes, VoIP providers might require to setup also the "Proxy" field. This happens when the domain is different from the proxy.
And that's all. Once returned back from the settings page, Linphone should say something like "Registered on XXXX" or "Registration on XXXX successful".
You can now place calls.
All other settings are for advanced users or geeks who want to play with the software.
