I prefer to tell people to change the SIP port, rather than disabling SIP in the router. There are a couple
of reasons for that:
- Some routers (like Fritz!Box) doesn't allow you to disable SIP
- Even if you disable SIP in your router, you may be remotely operating from a location where SIP on port
5060 is being used and you have no way to control that.
- Some 3G providers block port 5060
Of course, you still need to disable SIG ALG if you have access to the router.
