IP TELEPHONY
This service does not require any specific external equipment (IP and/or Proxy/Firewall Router), unless
it is provided for Remote/Home Workers.
The IP router (R) connected to the Intranet can be a simple IP router. The reservation of bandwidth is
"guaranteed" if this router supports IP ToS (DiffServ).
The number of remote IP Enablers or PIMphony IP subscribers depends on the line bandwidth (not
more than 2 simultaneous communications for 64 Kbps, not more than 5 for 128 Kbps).
