Configuring the IP Phones

Advanced Network Settings

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) using the Aastra Web UI or the configuration files.

Note: The available advanced network parameters via the IP phone UI are NAT, Nortel NAT, VLAN, and QoS only.

Network Address Translation (NAT)

The protocols used by all IP phones do not interoperate completely with Network Address Translation (NAT). For the Aastra 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.
