So as i changed my internet provider and got a new router, my N900 got a finishing touch. It is now my phone for my local number through SIP accounts.
One SIP account in the local net to the router, and one SIP account through the net. Real communication central now. Jabber, ICQ, Skype, SIP, Facebook Chat (Jabber) .. oh and you can use the old school phone function of course.
But who really uses phones nowadays 😉
