SRV record for non-standard SIP port?
Hello
To cut down on the number of hackers trying to break into an Asterisk
server, I'd like to simply move the SIP port from the standard UDP
5060 to something non-standard.
Since this server must be able to receive INVITEs from any SIP UA
(server or client), it appears that I must add an SRV record in the
DNS so that they can locate the server and the port used to reach it.
_sip._udp SRV
