Why did 'transport=tls' 'r2=on' 'lr=on' and 'nat=yes' all disappear after just adding 'record_route_preset("myurl.com");' (I had to edit my routing logic to fix a problem with kamailio sending record-route to WAN clients telling them to respond on my private NAT IP address)

# I'm concerned my edits to the routing logic is incorrect and would like a second opinion. (I added record_route_preset on line 41 and commented out line 42): http://pastebin.com/3azFStmE

# Here is what record-route looked like Before adding record_route_preset (3 lines): Record-Route: sip:66.111.222.111:5061;transport=tls;r2=on;lr=on;nat=yes Record-Route: sip:66.111.222.111;r2=on;lr=on;nat=yes Record-Route: sip:myurl.com;lr=on

# And now here is what they look like After adding record_route_preset: (1 line) Record-Route: sip:myurl.com;lr
