RSSNumb is a STUN/TURN server. Access is free.
“A STUN/TURN server is used for NAT traversal in VoIP. Whether you’re at home behind a common router, at work behind an enterprise firewall, or traveling, chances are that you will be behind a NAT which must be traversed before making calls.
Our server, Numb, will help your SIP phone automatically punch holes in the NAT. As a solution of last resort, it will simply act as a relay between you and the person you’re talking to when end-to-end connectivity just isn’t possible.
Numb is a free service by Viagénie.”
