Nortel Networks 7400 - Manual (Page 229)

Communications Manager IP PABX solution can be
added as an interface to control IP handset traffic
and to provide the IP-TDM gateway functionality.
For home workers using the i2050 soft client, an
IPSec session can be initiated from the home PC,
through the Internet to the corporate Contivity. All
VoIP traffic from the soft client traverses the secure
tunnel into the Enterprise where it exits the
terminated IPSec tunnel at the Contivity and
progresses forward to either the Meridian-1 ITG or
Business Communications Manager.
Users can utilise the microphone and speakers of
their PC, or plug in a USB headset for improved
quality.
Home workers utilising the i2004 IP phone for a
more permanent and "telephony-like" solution are
challenged by the need to create a secure tunnel. If
the PC creating the tunnel has routing functionality
and multiple network interfaces, the phone can plug
directly into the PC’s second Ethernet port. For most
situations, a Contivity VPN switch at the home office
provides an easier solution. The Contivity switch
opens up a branch tunnel between the home office
and the office, and secures all traffic between the
two sites. Everything that plugs into the Contivity
(phone and PC) is therefore encrypted and has IP
access to the corporate LAN – effectively creating an
Intranet VPN link to the home office.
