[OpenSIPS-Users] Does Opensips nat function handle Subscribe/Notify ?

[Manivasagam Sivaraman]

Do any one know if there is a function like fixed_nated_subscribe() , just
like fix_nated_register() ? I'm facing problem where opensips is not fixing
the natted subscribes ? I'm using rtpproxy for INVITE/Rtp and it works fine.

Please help
