Enabling the handset's DHCP client:

dynamic IP address

The handset is assigned a free IP address

each time it accesses the WLAN. The IP

address is not statically connected to the

handset. The IP address can change with

each access and during a connection. The

same IP address can be assigned to differ-

ent WLAN subscribers in succession.

The DHCP client is enabled by default.

Disabling the handset's DHCP client:

defining the IP address manually

You can disable DHCP and define the

handset's IP address manually.

You must make the following settings in

the access point and handset if you disable

the DHCP client.

u IP address: when you specify the

IP address of the handset, you should

use an address from the address block

that is reserved for private use. This is

generally the range 192.168.0.0 –

192.168.255.254.

If you use the default subnet mask (see

below) the first three parts of the static

IP address must be the same for all sub-

scribers in your WLAN.

u Subnet mask: To find out which values

you can use, see the user guide for the

access point (default: 255.255.255.0).

u Gateway: IP address of the gateway via

which the WLAN is connected with the

Internet (e.g. your router). Specify the

local IP address within the WLAN.

SIP account

To be able to use VoIP on the basis of SIP,

you need a SIP provider. A SIP or gateway

provider is a provider in the Internet, who

establishes the connection to the person

you are calling. As the handset works with

the SIP standard, your provider must sup-

port the SIP standard.

VoIP connections to the telephone net-

work are realized by a gateway.

The SIP provider provides you with a gate-

way for Internet telephony: the SIP pro-

vider forwards calls from VoIP to the tele-

phone network (analogue, ISDN and

mobile) and vice versa. Via a SIP or gate-

way provider in the Internet, you can

reach subscribers in the telephone net-

work and can be reached from the tele-

phone network.

To be able to use your SIP provider's serv-

ices, you must register with the provider.

To do this, you must open a so-called

account. The SIP provider can address you

via the account.

Standard SIP settings

For access to the SIP service, the settings

of different SIP providers may be preset in

your handset. They contain your SIP provi-

der's general access data, e.g. the SIP

proxy server address.

The SIP proxy server is the central

exchange for VoIP. The SIP proxy server

performs similar tasks to a standard PABX.

Its address comprises the following:

u IP address of the SIP proxy server. Alter-

natively, you can also specify the

domain name of the server.

u Communication port of the SIP proxy

server (Standard: 5060)

Note:

You can check the current IP address of the

handset (page 73).

Note:

All information required for the SIP settings

can be obtained from your SIP provider.
