<p class="MsoNormal">I am looking for a way to control the hostname part of the contact header. Reading the documentation I think set_advertised_address() is what I need but if I call set_advertised_address("FQDN") followed by topology_hiding("UC") the contact
header is incorrect.<u></u><u></u></p>

<p class="MsoNormal">If I set 'listen=tls:XXX.XXX.XXX.XXX:5061 as FQDN:5061' and only call topology_hiding("UC") then the contact header hostname is set to FQDN.<u></u><u></u></p>
