Allow access from other networks

The default setting for you phone is that

you can only access your phone's Web

configurator via a PC that is in the same

local network as your phone. The subnet

mask of the PC must match that of the

phone.
You can also allow access from PCs in

other networks.

Open

Settings

IP configuration

Web

page.

In the

Remote Management

area, activate

the option

Yes

to permit access from

other networks.
To deactivate remote access, click on

the

option. Access is then limited to

PCs in your own local network.

Access to the Web configurator services

from other networks is only possible if

your router is set accordingly. The router

must pass on the service requests from

"outside" to Port 80 (standard port) of the

phone. Please also read the user guide for

your router.
To establish a connection, the public IP

address or the DNS name of the router

and, where applicable, the port number

on the router, must be indicated in the

Web browser of the remote PC.

VoIP telephony

Make the settings that your phone

requires to access your provider's SIP

server. For the majority of VoIP providers,

you can make the most important setting

on your handset (page 42). The Web con-

figurator allows you to extend the possibil-

ity of these settings.
If your VoIP provider general settings are

not available for download in the provider

list on the Internet, you must make these

settings using the Web configurator as fol-

lows.

Open

Web page.

In the working area, enter the configu-

ration data as listed below into the

Area:

SIP

Enter the configuration data that is neces-

sary for accessing your VoIP provider's SIP

service. You will receive this data from

your VoIP provider.

Authentication Name

Specify the registration or authentica-

tion Id agreed with your VoIP provider.

The registration ID serves as the access

ID that your phone must specify when

registering with the SIP proxy/registrar

server. The

Authentication Name

mainly identical to the

Username

, i.e. to

your Internet phone number.

Authentication password / Confirm

authentication password

Enter the password that you have

agreed with your VoIP provider in the

Authentication password

field. The phone

needs the password when registering

with the SIP proxy/registrar server. The

password is concealed when entered.

Re-enter the password in the

Confirm

authentication password

field.

Warning:

Expansion of access entitlement to other net-

works increases the risk of unauthorised

access.
It is therefore recommended to deactivate

remote access again if you no longer need it.
