I have a SIP proxy in a network and a UAC in another network. So, there is a NAT.

When the UAC tries to register on the SIP proxy, it get  "Status: 403 Preload Route denied".

What does mean such issue in this context?

What is a common solution for this case?

When SIP proxy and UAC is in a same network, all work ok.

Any hint will be very helpful!

Best regards.
