IPT Anywhere
System Availability: All systems
IPT Anywhere enables you to connect IP telephones remotely through the Internet and use all Strata
CIX telephone features. IPT remote connections can be set with or without the use of Virtual Private
Network (VPN). VPN connections provide increased security and are recommended for permanent
type IPT remote connections. When moving IPT telephones frequently to different locations (hotels,
conferences, etc.), non-VPN connections are more practical.
When using home type xDSL or cable connections, only one or two IPTs may be connected
because of xDSL and cable bandwidth limitations. High speed T1, fiber, or Asynchronous Transfer
Mode
(
ATM)-type connections are required when installing more than two IPTs at a remote site.
An Internet configuration could use the following connections:
•
No VPN, and thus, no security
•
Third party VPN software residing on DHCP gateway server. To connect IPTs over the Internet,
using third party or Microsoft VPN software residing on a DHCP gateway server, see
Figure 15
.
•
ATM (IP over ATM virtualization by VC/VP)
•
Broadband Ethernet virtualization by Virtual LAN (VLAN)
•
IP-VPN (IP-VPN based on Multi-protocol Label Switching (MPLS)
•
Private line connection
For an access line to link the user’s location with the access point of the carrier or provider, using a
private line, broadband line (xDSL, CATV), or fiber optics is recommended.
The IPT Anywhere feature enables remote IP telephone users working in branch offices or home
offices to make full use of the extension features of the Strata CIX. The diagram below shows IPT
Anywhere connections using the optional VPN conection.
