SERVICES AND TOPOLOGIES CALL SERVER : VOICE ON IP
Ed. 046/12 Réf. 3EH 21000 BSAA
The connection between the Home Worker and the Internet must be 'always-on' (ADSL, cable, etc.). It
is indispensable to have an IP/Proxy/Firewall router or VPN server on the Home Worker side.
The IP router (R/F) at the front end of the VPN must offer Proxy/Firewall and VPN server functionality
(IPSec with 3DES encryption for interoperability with the system's built-in router).
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).
