Chapter 1
IX-4EVMC
Remote Internet Connection
The instructions provided in this section of the document assume the procedures outlined in the
Configuring the IX-4EVMC for IP Connection section was properly performed.
If programming the IX-4EVMC over the internet, the Omega-Voice VMI editor must be able to
communicate with the IX-4EVMC card. This is often done using three different approaches.
Public IP Address
One approach to remotely programming the IX-4EVMC over the internet is to assign a public static IP
address to the IX-4EVMC. This IP address is provided by the network administrator and allows the
IX-4EVMC to be accessed remotely.
VPN Connection
Another approach to remote connection uses a VPN connection. The network administrator will
provide the necessary IP address, username and password so a VPN connection can be establish. Once
the programming PC logs onto the VPN, use the private IP address assigned to the IX-4EVMC in the
Configuring the IX-4EVMC for IP Connection section to connect to the voicemail card.
NAT/PAT
The final approach to remote connection uses a Network Address Translation (NAT) or Network
Address Port Translation (NAPT). If either is used, the network administrator must set up port
forwarding in the router. The IX-4EVMC uses UDP port 8192.
In this case, the Omega-Voice VMI Editor will use the network’s public IP address assigned in
Configuring the IX-4EVMC for IP Connection section to connect to the voicemail card. The router will
automatically forward all UDP port 8192 information to the IX-4EVMC.
