> I've been testing directmedia with endpoints and see failures in about 1 out of 5 attended transfers.  It's using the endpoint's internal network address rather than the external IP.  The server is at a public IP and the endpoint is behind NAT.  I changed the IP the enpoint is behind to 1.1.1.1 and the sip provider's IP to 2.2.2.2.
> I thought it was the same as ASTERISK-23497 but it seems to be different and it wasn't fixed by upgrading from 12.2.0 to 12.4.0.
