Daniel,
I don't want to use record_route_preset at all, since its use is very complicated when Kamailio is listening on multiple IP addresses and when request can come over UDP, TCP, or TLS and when R-R URIs can have many parameters depending on if rtpengine is used, etc.
So I simply want to keep on using record_route() as before, but tell it to use a FQDN instead of IP address of the proxy in the first or second R-R header that it is adding.

suggest to replace record_route(); call with
record_route_preset("SBC-DNS-DOMAIN:5061;transport=tls", "SBC-IP-ADDR:5060");
That works only in a very simple case where the request came in over UDP or TCP and SIP Proxy has only one listening address, i.e., SBC-IP-ADDR.
One way to solve the problem might be a new r_r function that would take FQDN of the top R-R URI as argument or introduction of a pv from where the current record_route() function would take the FQDN if it has been set.
Any comments or other solutions?
Not sure I understand: do you want to get the value of the second parameter for record_route_preset() based on local sockets where the request was received?
Cheers, Daniel
