It is unclear if the Voice component can be configured by pointing the FXS ports to a SIP server of our own, or if this is locked down to cellular voice only. None of the wholesale SIMs we purchase have voice capability so this would not work for us if it relies on cellular voice.
I need this is as well. I think the TAM (total addressable market) would be very large. There are quite a number of CLECs and ILECs paying AT&T large sums every month for there copper line connections. I think a cellular ATA would address most of this market. I would like the option of VoLTE or Cellular ATA in this box.
Very interesting unit - is there an optional HW with WAN / DIA port for Dual path option? And a 5G version ?
We deploy a lot of POTS replacement kits for Fire/Elevator/Other emergency line services that would require the dual path.
Also like the idea of a SIP unit if ever developed - since we too have our own Switch infrastructure
