Advanced Network Settings

You can set advanced network settings on the IP phone such as, Network Address
Translation (NAT), Nortel NAT, Network Time Protocol (NTP) Time Servers,
Virtual LAN (VLAN), and Quality of Service (QoS), and Universal Plug and Play
(UPnP) using the Aastra Web UI or the configuration files.
Network Address Translation (NAT)
The protocols used by all IP phones do not interoperate completely with Network
Address Translation (NAT). For the IP Phones, specific configuration parameters
allow the phone to operate while connected to a network device that enforces
NAT. The following is a sample network using a NAT proxy and relevant IP
phone configuration parameters.
4-30
Note: The available advanced network parameters via the IP phone UI
are NAT, Nortel NAT, UPnP, VLAN, and QoS only.
