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!

Hi and welcome to the forums, turn your phone upside down and double check that you have plugged the handset lead into the correct socket as per the image below:

I suspect you may have it connected to the headset socket.
