Question: how can I advertise and later match multiple FQDNs per socket?

Example:

auto_aliases=no
alias="mydomain.net":5060
alias="mydomain.net":5061
alias="client1.mydomain.net":5060
alias="client1.mydomain.net":5061

# looks like I can advertise only one address per socket?
listen=udp:65.65.65.65:5060 advertise "mydomain.net":5060
listen=tls:65.65.65.65:5061 advertise "mydomain.net":5061

Adding RR before relaying downstream like so:

record_route_preset("client1.mydomain.net:5061;transport=tls;r2=on", "client1.mydomain.net:5060;r2=on");

This is the warning (just warning, works fine otherwise) after receiving for example the ACK from upstream following the 200 OK:

WARNING: {1 19082 ACK  } rr [loose.c:768]: rr_do_force_send_socket(): no socket found to match second RR (sip:client1.mydomain.net:5061;transport=tls;lr;r2=on)

Figured warning itself can be turned off with modparam "enable_socket_mismatch_warning" of RR, still I'd like to know if I'm doing something wrong or there's a better way.

Much obliged,
