Hi Carlos. Thanks for that. I thought before I change this, I'd let you know the current settings. So in one server, in the file SIP profiles\external.xml, there is: <param name="rtp-ip" value="$${local_ip_v4}"/> <param name="sip-ip" value="$${local_ip_v4}"/> <param name="ext-rtp-ip" value="<static IP address>"/> <param name="ext-sip-ip" value="<static IP address>"/> So that appears to be correct. I think at some stage I must have hard coded those static public IP addresses. For the other server, that same file shows: <param name="rtp-ip" value="$${local_ip_v4}"/> <param name="sip-ip" value="$${local_ip_v4}"/> <param name="ext-rtp-ip" value="$${external_rtp_ip}"/> <param name="ext-sip-ip" value="$${external_sip_ip}"/> So this file is picking up the global variables. I've found these defined in vars.xml: <X-PRE-PROCESS cmd="stun-set" data="external_rtp_ip=stun:stun.freeswitch.org"/> <X-PRE-PROCESS cmd="stun-set" data="external_sip_ip=stun:stun.freeswitch.org"/> I presume the STUN server would return the same static IP address. So do you think it would make any difference setting these to auto-nat? Cheers.

Try adding this: <param name="ext-rtp-ip" value="auto-nat"/> <param name="ext-sip-ip" value="auto-nat"/> With this, your FS servers will send the correct IP on SIP and SDP and the audio should work both ways.

Hi everyone.
I have a need to run two separate Freeswitch PCs behind my router and I'm trying to figure out the best way to do this.
For the first PC, in vars.xml I have set external_sip_port to 5060 and its TLS equivalent to 5061, and in switch.conf.xml I have set rtp-start-port to 17408 and rtp-end-port to 17920. For the second PC, in vars.xml I have set external_sip_port to 5040 and its TLS equivalent to 5041, and in switch.conf.xml I have set rtp-start-port to 16384 and rtp-end-port to 16896. On the router I have opened up UDP port 5060 and UDP ports 17408 to 17920 to the IP address of the first PC. I have opened up UDP port 5040 and UDP ports 16384 to 16896 to the IP address of the second PC. Things are half working. But when I phone in on a number that should connect to the first PC, the call goes through and I can answer it, but I'm only getting audio one way.
Is there more I have to do to get Freeswitch to only use a certain range of ports for RTP so I can route correctly and avoid clashes? What am I missing here.
Cheers.
