[Asterisk-Users] I stumbled on this list...

[Philipp von Klitzing]

Hi!

> I have my sister who is living in Germany.  We both use broadband.  

If you have a dynamic IP or are not permanently on-line: Let your sister 
register with FWD (Free World Dialup, fwd.pulver.com) and use that to 
call her. You can do the same with your Asterisk box, i.e. let Asterisk 
register with FWD.

If you have a static IP and are on-line 24/7: She can register her SIP 
software phone or hardware phone with your Asterisk directly. Anyone else 
who wants to call her has to call your Asterisk server.

Hope this helps,
Philipp
