Have been getting constant registration attempts to my asterisk server from since 1-sep-2011. Address has been blocked on my firewall but attempts have not stopped.

In the last few weeks, I've seen a number of attacks using my asterisk server to phish and phone-spam all over the US

Used by SIP VOIP phones, X-ten Lite/Pro for instance. Thus VOIP providers, such as use this.

This is one of the ports Vonage uses to connect to the Analog Telephone Device that they provide. Other ports are UDP 5060-5061 and UDP 10000-20000
