Re: Are you ready for SPIT?
No ... no .... no .... no.
SIP Authentication is done with an authentication username and authentication realm. This should be implemented by any consumer VoIP service.
Somebody can't just send a SIP INVITE to your TA and make your phone ring. The SIP Proxy and the SIP Agent will only accept SIP messages from each other upon proper authenication.
Could SPIT happen to "open" SIP devices on the net, yes. But, not to a commercial service. |

| Actually, here's an SIP Proxy sending back an "Unauthorized". |

When the SIP phones becomes more common place most people might choose to SIP Phone to SIP Phone communications for some of their calls (along with DynDNS style registration). |

Gainesville, VA | Fair enough. When this has come up before, most people assumed it could happen to their Vonage, SunRocket, etc. accounts. |
