Hi,

I’d read the manuals and configure my sofia profile to work with the external IP in the ext-rtp-ip setting.

<param name="stun-enabled" value="true"/>

<param name="stun-auto-disable" value="false"/>

<param name="ext-rtp-ip" value="stun:stun.freeswitch.org" />

The Freeswitch is started with the parameter –nonat

In the pcap trace is no STUN request visible.

I try to restart the Freeswitch, restart the profile, do an outbound call, but there is no STUN request.

If I try to get my external IP via the CLI cmd “stun stun.freeswitch.org”, then works it successfully.

The status output of the profile is:
