Network Parameters
To use IP-PTs at the remote office, you will need to have the IP addressing and VLAN ID information
described in "1.1.1 Using IP Proprietary Telephones on a Local Office LAN".
Types of IP Network
When using IP-PTs over LANs at different locations, first confirm the type of IP network connecting the
LANs. The speech quality depends on the type of IP network in use. Managed IP networks provide better
speech quality compared to unmanaged networks such as the Internet, where quality of service cannot be
guaranteed.
Note
Unlike an IP-VPN, which is set up over a network provider's own IP network, an Internet VPN is set up
over the Internet. Internet VPNs are not recommended for IP-PT communication because transmission
delays and loss of data are likely to occur.
