I'm trying to setup a ER-605 for a old VOIP service that can utilize a VPN for phone calls. 

I have an OpenVPN server running on a PFSense firewall.  I have a static IP on the server.  I created a OVPN file (shown below). it doesn't appear the device is connecting properly.  I have two other open vpn instances that are working fine, but this one won't connect.  Is this unit capable of this connecton?
