[OpenSIPS-Users] Opensips relaying MESSAGE - source IP problem

[Sebastien CRUAUX]

Hi Jose,

This option is not set in my config but actually I managed to figure out 
things using the "ie" and "ei" flags in the 
rtpproxy_offer/rtpproxy_answer fonctions.
Thanks for your help !

Best Regards,

Sebastien
