Hi Joshua,
try to debug your script:
1) is the nat flag set for the re-invite
2) is the force_rtp_proxy called?
3)......
regards,
bogdan

Hello,
I am new to openser and rtpproxy. I have tried to configure openser so that
reinvites are also handled by rtpproxy. It seems however that they are not.
I have included my config below:
debug=9
fork=yes
log_stderror=no
check_via=no
dns=no
rev_dns=no
port=5060
