What’s FreePhone?

Where’s the point in using a phone flat just for a single person? !FreePhone is a project aimed to develop a VPN wide SIP phone service. Calling german landline is possible at the moment, as well as local participants (eg. maxx).

Set up your softphone or hardware implementation to use:

Special needs

Just contact me if you like to use your SIP hardware (eg. Fritz!Box FON). You’ll get a special account allowing registrations plus a local extension.

Restrictions

Additional extensions

| Extension | Target | |—|—| | maxx | myself, almost anywhere wireless lan is availiable | | grim | sometimes, sometimes not | | equinox | i think nokia prevents but you may try | | helios | did not connect for some time now |

If you like listening to german news, dial 787326353 (Vanity: STREAMDLF). Just contact me in case you want more.

Configuration examples

Just look at the german version, you’ll get the idea.

What’s next?

Real dn42 phone system
