Hello, I have enabled RTP proxy on my machine (ec2 instance) by running the following script:

rtpproxy -F -l mypublicip -s udp:localhost:7722

but I keep getting this error. The phones ring but there is no audio:

3(4144) ERROR: rtpproxy [rtpproxy.c:2647]: force_rtp_proxy(): incorrect port 0 in reply from rtp proxy

can someone let me know what this error means?

Thank you,

Arun
