I have a TDA200 with digital terminals, but we a requirement where 4 wireless phones are required on a remote location (wireless mandatory).

The remote location is going to be connected trough VPN to the office with the TDA200. I have seem that the the cell stations TDA015x require a wired connection back to the PBX, any other idea on how o get those 4 wireless phones connect to the main location?

Tahnk you
