[OpenSIPS-Users] NAT handling on a chain of proxies

[mayamatakeshi]

Hello,
is there an easy way to check if my opensips instance is the last proxy
before the UAS?
I need this to avoid calling nat_uac_test/fix_nated_contact in my
onreply_route in case I'm receiving a response relayed by another proxy.
I was thinking I could test if i'm in the top-most Record-Route in the
reply, but I was unable to figure out how to do it.
(to avoid calling fix_nated_contact in requests, i think I can use
textops:is_present_hf).

regards,
takeshi
