[Freeswitch-users] Can't change external RTP IP

Hi guys, I am trying to change expternal_rtp_ip for one of my sip profiles. To make thing as simple as possible, I changed it in the internal profile (internal.xml). I just set it to a literal IP address. Then I registered a soft phone on the FS and tried to make a call. The call went through and FS console said that it connected to vociemail but I could not hear anything. Wireshark said that the SDP address that FS sent back is still FS's internal IP address. Any ideas what we are doing wrong? Thank you *Oleg*
