Yes, problem was the firewall of the softphone pc. I also found another problem. When I used linphone for the softphone client, the agent could't hear voice from linphone. I have set "Direct connection to the Internet" of the linphone but still got the one way audio. Thank you all. JImmy ? 2013/3/28 ?? 12:10, Steven Ayre ??:
That will have no effect. That's for setting the port range, and those are already the defaults.
You may find opening that port range on your router's firewall may help though.

Hi,
I could make a call within NAT without any problem. When I made a call from internet, I got no audio. I have read the document
http://wiki.freeswitch.org/wiki/NAT_Traversal
and set the parameters. vars.xml <X-PRE-PROCESS cmd="set" data="bind_server_ip=my.server.ip"/> <X-PRE-PROCESS cmd="set" data="external_sip_ip=my.server.ip"/> <X-PRE-PROCESS cmd="set" data="external_rtp_ip=my.server.ip"/> internal.xml <param name="ext-rtp-ip" value="$${external_rtp_ip}"/> external.xml <param name="ext-sip-ip" value="$${external_sip_ip}"/> <param name="ext-rtp-ip" value="$${external_rtp_ip}"/>
Any advice? Thanks. Jimmy
