I would assume that this is the "Local SIP port" specified in your hardware device (usually under the Account tab on a Grandstream phone or ATA).
I have used different ports (5060 to 5070) to prevent conflicts and it seems to work fine.

On your router, you should forward that Port or Port range to the private IP address of your SIP device.

This set-up works best if you set up your devices with a fixed private IP, program the local SIP port to for Eg 4060, then forward this port on the router to the IP address set up for the device.

This of course assumes your device is behind a router that you control.
Also, use a STUN server in your device set-up (Eg. stun.voxalot.com.au:3478).
If you are doing this behind a corporate firewall, the IT department may have totally blocked these ports and probably there is not much you can do to fix the problem.
