All of the settings for connecting your phone to the local network must be correct to enable commu nication with other devices in the network and phone calls via the Internet.
If you use the Web configurator, your phone is already connected to the local network. You can use the Network and Connections menu to change and extend these settings. You can also create set tings for phone connections:

LAN settings

Settings -> Network and Connections -> Local Area Network (LAN)

VLAN tagging

A local network can be divided into logical subnetworks known as VLANs (VLAN = Virtual Local Area Network, Standard IEEE 802.1Q). Multiple VLANs share a physical network and its components, e.g., switches. Data packets from a VLAN are not forwarded to another VLAN. VLANs are often used to sep arate the data traffic of different services (Internet telephony, Internet TV etc.) and to define different priorities for the data traffic. 
You can operate your phone and a PC connected to the PC port on your phone in two different VLANs. In this case, you enter the VLAN identifiers (VLAN tags) for your VLAN. Your network operator will supply you with this data.

• Select the required priorities for voice and data transmission for the LAN port from the Voice Priority and Data Priority menus. 
• If you selected LAN and PC Port, select the VLAN Priority for the transmission of PC data as well. 

Prioritising VLANs

Data packets from VLANs can be prioritised. The priority determines whether the data traffic from a VLAN is given preferential treatment by the network components. You can define the priority for voice and data separately. In the case of a local network with a lot of data traffic, you can achieve bet ter quality phone connections by giving a high priority to voice data. Using a high priority for data services you can achieve better quality for displaying info services such as webcam images or maps. 
Range of values and assignment of values to service classes (according to IEEE 802.1p):

Own HTTP server settings

If you operate your own HTTP server, enter the communication data.

HTTP port

Enter the number for the port to be used for communication by the HTTP server. The default setting is 80.

HTTPS port

Enter the number for the port to be used for secure connections by the HTTP server. The default setting is 443.

HTTP connection type

Select which connections can be established:

Automatically logout (min.)

Enter the time (in minutes) after which an HTTP connection should automatically end if no entries are made.

Phone Systems

If you operate a phone system in your local network, use this screen to configure access to your phone.

Settings -> Network and Connections -> Phone Systems

If your phone is connected to a phone system, select what type of phone system it is, e.g.

Call Manager

If your phone is connected to a phone system, you can decide how to handle incoming and outgoing calls for different situations. The availability of the following options depends on the selected phone system. 
For the following situations: 

• Incoming calls that are transferred by the phone system's call manager (Accept call directly), 
• Incoming calls that are not transferred by the call manager (Incoming Calls without Call Manager),
• Calls that you initiate via a function key (Outgoing Calls via function key)
• Other outgoing calls (Execute call), 

you have the following options to accept/execute the call: 

• via headset 
• via handsfree or
• not at all (No) (incoming calls)

BLF list IP address (URI) (only for Broadsoft)
Busy Lamp Field (BLF) features allow users to view the status of phone lines that are associated with specific phone features. Using BLF pickup, it is possible to answer an incoming call for all lines on the Maxwell 10 that the phone is allowed to monitor. Which BLF features are configured for the phone is defined on the phone system. 

• In the BLF list user field, enter the IP address (URI) of the server providing the list of devices for which the phone is able to accept incoming calls. 

This function is only available if supported by the phone system. 

Extended service platform PBX of service provider

• If your provider provides extended PBX services, enter the Server Address and the phone sytem account data, e.g. UCI Login-ID and the UCI Password. The necessary data to be entered depend on the selected phone system. 

Saving settings

• Click on Save to save your settings on the Phone Systems screen.

QoS settings (Quality of Service)

On this screen you can optimise the voice quality of your IP telephone. 
The voice quality depends on the priority of the voice data in the IP network. Prioritising the VoIP data packets is done using the QoS protocol DiffServ (Differentiated Services). DiffServ defines a number of classes for the quality of service and, within these classes, various priority levels for which specific prioritisation procedures are defined.
You can specify different QoS values for SIP and RTP packets. SIP packets (Session InitiationProtocol) contain the signalling data, while RTP (Real-time Transport Protocol) is usedfor the voice transfer.
Settings -> Network and Connections -> Quality of Service (QoS)

Saving settings

• Click on Save to save your settings on the Quality of Service (QoS) screen.

VoIP settings

On this screen you configure the ports for establishing VoIP connections.

Settings -> Network and Connections -> VoIP

"Listen ports" for VoIP connections

Use random ports

• Select Yes if the phone should use any available ports for the SIP port and RTP port instead of fixed ports. 
  The use of random ports is advisable if you want multiple phones to be operated on the same router/gateway with NAT. The phones must then use different ports so that the NAT for the router/gateway is only able to forward incoming calls and voice data to one (the intended) phone. 
• If you click on No, the phone uses the ports specified in SIP port and RTP port.

SIP port

Specify the local communication port that the phone should use to send and receive signalling data. Specify a number between 1024 and 49152. The default port number for SIP signalling is 5060.

RTP port 

Specify the local communication port that the phone should use to receive voice data. Enter an even number between 1024 and 49152. The port number must not be the same as the port num ber in the SIP port field. If you enter an odd number, the next lowest even number will be selected automatically (e.g., if you enter 5003, then 5002 is set automatically). The default port number for voice transmission is 5004.

ICE enabled

Choose whether or not to use ICE (Interactive Connectivity Establishment). ICE is similar to STUN (a Session Initiation Protocol (SIP) method for overcoming NAT firewalls.

Saving settings

Security settings

This screen is where you create security settings for your phone.

Settings -> Network and Connections -> Security Settings

Remote management

• Select whether you want to Allow access from other networks to the web configurator (Yes) or not (No).

If you permit Remote Management, this increases the risk of unauthorised access to yourdevice settings.

• Select the network protocol to be used for the communication:

• • TLS (Transport Level Security)
    
  • UDP (User Datagram Protocol
  • UDP (Transmission Control Protocol)

 Security settings

On this screen you can download server certificates onto your phone, delete downloadedcertificates and specify how invalid certificates should be handled.
Server certificates allow a server to be digitally identified via SSL (Secure Sockets Layer). Operating a server with SSL requires a server certificate both for one-way authentication (server to the client) and for two-way authentication (between client and server). A server certificate has to be downloaded onto your device so that the device can carry out authentication.
The Server certificates and CA certificates lists contain all downloaded certificates.

• Select a certificate from one of the lists.
  
• Click on Remove to delete the certificate from the list.
• Click on Details to display information about the certificate.
• Click on Disable/Enable to temporarily deactivate/activate the certificate.

Import a local certificate

In order for a certificate to be downloaded to your phone, it must be available in your network.

• Click on Browse to search for the file on your PC or in your network. Select the required file.
• Click on Upload to download the file onto the device.

Secure Real Time Protocol (SRTP)

The Secure Real-Time Transport Protocol (SRTP) allows you to encrypt voice data transmitted using the Real-Time Transport Protocol (RTP). 

• Activate or deactivate the Secure Real Time Protocol (SRTP).
• Select whether you want to Accept non-SRTP calls or not. If this function is activated, you also accept incoming calls from a number that does not use SRTP.
