Actually, with NAT, you have to use an STUN server to communicate the

Perhaps some servile providers configure their systems so to make it necessary, but mine certainly doesn't!
In fact they insist that a STUN is NOT to be configured.
OK, your VoIP phone is behind NAT, with an RFC 1918 address. The other end has to be able to reach your phone. What address does it use? And how does it get it?
Linksys ATA is using SIP NAT traversal. So yes, in this case separate STUN server is not needed. Which does not mean of course that two VoIP communicate directly without any help. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
