[Freeswitch-users] Issue: INCOMPATIBLE_DESTINATION / AUDIO RTP REPORTS ERROR [Missing local host]

We normally use "proxy_media=true" and this is the situation that triggers
the issue.
IPs provided are modified into 10.20.30.xx form, but we use public IPs, so
no NAT is involved, hence both parameters have default values like:

    <param name="ext-rtp-ip" value="auto-nat"/>

    <param name="ext-sip-ip" value="auto-nat"/>

Thanks
Maciej.
