Changing the default external access ports
SIP communication commonly uses TCP or UDP port 5060 and/or 5061. Port 5060 is used for nonencrypted SIP signaling sessions and port 5061 is typically used for SIP sessions encrypted with Transport Layer Security (TLS).
|
Avoid changing any of the protocol ports to four digit numbers, such as 5065 or 5070, as those are used by other brands and are commonly scanned port numbers. |
