calls between two endpoints communicating via IPv4. It communicates with other systems via
IPv4 only.
■
IPv6 only: it only accepts registrations from endpoints using an IPv6 address, and only takes

IPv6 only.
■
Both: it accepts registrations from endpoints using either an IPv4 or IPv6 address, and takes
calls using either protocol. If a call is between an IPv4-only and an IPv6-only endpoint, the
Expressway acts as an IPv4 to IPv6 gateway. It communicates with other systems via either
protocol.
