[OpenSIPS-Users] Help!! error: use_media_proxy(): empty response from mediaproxy

[Krunal Patel]

Hi

As request is coming from Public IP , use_mediaproxy is not being called for
invite.
But callee is behind NAT that's why use_mediaproxy has been called in reply
route.

One more thing, I have put force_rport at the beginning of main route , I
have removed that & the issue is fixed.
but Now facing signaling issue in case internal & external port are
different for nated client.

Please advice what to do

Thanks
