malformed SIP / routing issue

I wonder what conditions might lead, that SIP packets from provider
P destined to my external SIP server A, are reaching my internal SIP server

the fun factor is that internal B server is used for outbound calls via the
same provider P.

I found no routing issues.

Is it possible to build SIP header specifying the final destination – the
internal IP address?

  • Surely. B responds “404 Not Found.”, as it’s not configured to receive these
    SIP packets.

    provider P sends to correct IP, and moreover B has no external IP.
