Sip-Communicator - latest Ubuntu sip phone

Sip-communicator promises to be easier, better, and more open than the competition. I've only just installed it but it looks like a winner.

Add this PPA:

deb http://download.sip-communicator.org/deb unstable/

Then go to a terminal and type the following commands:-

apt-get update

apt-get install sip-communicator-keyring

apt-get install sip-communicator

Then go into Applications -> Internet -> SIP Communicator
