SIP is the standard protocol for communication establishments on the plain Internet, published by IETF, under the RFC 3261. (We don’t only support FreeSoftware…. We support also open standard, open protocols, open APIs, open data formats…)
One of its main usage is the establishment of voice phone communication (plain phone calls), using the Internet instead of telcos.

We are reachable through the SIP address:

To reach directly an extension, just add it to the number.
As example:
(instead of +352 20.333.222-85)
You don’t need any SIP service provider.
This communication will not cost you more than browsing the Internet.
You just need a “SIP client” software, such as:
