VoIP hardware is developing fast - this is where you ask all those “how do I make my SIP Telephone, Adapter or Asterisk box work with my voip provider?” questions.

I WANT to love the Snom 300, but my first impressions are not great.... it wouldn't work on a real IP address outside of our network. (It took Support a little while to admit defeat on this point - they updated the firmware to the most recent).

I got it working sitting behind of firewall - but the volume of the handset won't save, and the volume control buttons don't work properly. So everytime we answer a call currently with the Snom 300, we can't hear the person on the other end!

Took the query to Snom Support.... and I'm awaiting an answer!

Our first phone was a Grandstream 2000, but is actually quite good. Seems to un-register too frequently though!
