Normally a SIP device will give it's public IP address as the RTP contact address. If the 7404VGPM is on a local network then it may be sending it's LAN IP address as the RTP contact address.

You can try placing the 7404VGPM directly on a public IP address, or use a stun server, or there may be a setting in the 7404VGPM where you can manually enter the public IP address.
