It’s absolutely OK, because when mid-registrar
re-send a REGISTER, it does not change the IP address
in the Contact: header.
So, when the ‘main server’ sends an INVITE to the end-point,
it sends it not to the mid-registrar, but to the IP address
being pointed in the Contact: header.</pre></div><div> </div><div data-signature-widget="container"><div data-signature-widget="content"><div>-----------------------------------------------<br><span style="font-size: 15px;">BR, Alexey</span><br style="font-size: 15px;"><span style="font-size: 15px;">http://alexeyka.zantsev.com/</span></div></div></div></div></BODY></HTML>
