Connect phone to local network (LAN)/router.
¤Settings Network IP Configuration
In most cases, special settings are not required to connect the phone to the router/a local
network. Your phone is preconfigured for dynamic assignment of the IP address by default
(DHCP). In order for your router to "recognise" the phone, dynamic IP address assignment must
also be activated on the router, i. e. the router's DHCP server must be activated.
If the DHCP server cannot or should not be activated, you must assign a fixed/static IP address
to the phone. A fixed IP address is useful, for example, if port forwarding or a DMZ is set up on
the router for the phone.
You can use the web configurator to make further settings that are required if you connect your
phone to a large (company-wide or organisation-wide) network, or if you want to manage the
•Specify the address of an HTTP proxy server within the LAN that the phone can use to
establish connections to the Internet if direct access is not allowed in the LAN.
•VLAN identifier / VLAN priority Store for access to a tagged VLAN.
•Allow PCs outside your LAN to connect to the web configurator.
The phone supports the establishment of secure data connections on the Internet with the TLS
security protocol (Transport Layer Security). With TLS, the client (the phone) uses certificates to
identify the server. These certificates must be stored on the base.
¤Settings Network Security
On this page, you will find the Server certificates / CA certificates lists with the certificates saved
on the base.
The Invalid certificates list contains the certificates received from servers that have not passed
the certificate check when establishing a connection, and certificates from the Server
certificates / CA certificates lists that have become invalid (e. g. because they have expired).
You can remove certificates and download new certificates to the base, and you can also accept
or reject invalid certificates.
If the connection to a data server on the Internet is not made because the phone does not accept
the certificate received from the server (e. g. when downloading your e-mail messages from the
POP3 server), you will be prompted to open the Security settings web page.
Authorising access from other networks increases the risk of unauthorised access. It
is therefore recommended that you disable remote access if you no longer require it.
The web configurator can only be accessed from other networks if your router passes
on the service requests from "outside" to port 80 (the default port) of the phone.
Make sure you read the user guide for your router.
