Are there any 'hidden' SIP trunk resilience options that we cannot see in the GUI? [My reseller is going to the Master Tech Class soon.]

We only see one Public IP address field for each of the SIP24 cards [we have 5]. If there is a secondary Public IP address option that can we can add IP addresses from our secondary fiber Internet circuit that would be ideal.

Otherwise we are going to have to look into using BGP to advertise the single Public IP addresses on the SIP24 cards. Not the end of the world but it would be a nice option.
