Hi Brian, Thanks for you response. After doing research, the two endpoints(uac, uas) wants to speak with different media format, that cause the freeswitch reject the rtp flow. But could you give me an detailed explain on the meaning of nbound-bypass-media and inbound-proxy-media? Does nbound-bypass-media mean that rtp flow directly from endpoint uac to endpoin uas, and inbound-proxy-media mean that rtp flow from endpoint uacfirst arrive freeswitch, and freeswitch forward it to the endpoint uas?

Zero for the port means something please provide a complete sip trace. /b

Hi,
I meet a issue about the rtp port. The media port value in the sdp of SIP 200 OK which freeswitch internal sends to ua is always 0, so the media forward is always wrong. What could cause this problem possibly?
No matter I set <param name="inbound-bypass-media" value="true"/> or <param name="inbound-proxy-media" value="true"/> The problem always showes.
Does the following rtp-ip and ext-rtp-ip set correct? In external.xml, I set both rtp-ip and ext-rtp-ip as $${external_rtp_ip}, is that correct? I am not clear about this two variables in the external.xml and internal.xml
external.xml: <param name="rtp-ip" value="$${external_rtp_ip}"/> external.xml: <param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
internal.xml: <param name="rtp-ip" value="$${internal_rtp_ip}"/> internal.xml: <param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
Thanks, -Congxin
