Step 4: Connect IPTs to Network

The following diagrams are examples of IP connections to either a hub, LAN or VPN network.

IPT Connections

Figure 9-8shows how the IP components should be connected. Refer to the Strata CTX Programming manual for IPT programming procedures.

IPT Anywhere

IP Telephony and QSIG Over IP

IPT Anywhere enables you to connect IP telephones remotely throughout the Internet and use all Strata CTX telephone features (except Speaker OCA). IPT remote connections can be set with or without the use of Virtual Private Network (VPN). VPN connections provide increased security and is 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 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 (BIPU-M2A)

Third party Virtual Private Network (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 9-9.)

ATM (IP over ATM virtualization by VC/VP)

Broadband Ethernet virtualization by Virtual LAN (VLAN)
