Configuring Advanced Settings

Setting up Internet telephony (VoIP)

The Gigaset SX763 WLAN dsl allows you to make telephone calls via the Internet using

an analogue telephone and also via the fixed network as usual. For Internet telephony

(

VoIP

), you require access authorisation from your service provider and the relevant

access data. To make calls, you have to enter this data along with other configuration

settings under Advanced Settings in the

Telephony

-

VoIP

menu.

You can connect a base station for handsets or fax machines to the two telephone ports

of the Gigaset SX763 WLAN dsl analogue phone. In addition, you can set up additional

extensions for Internet and fixed network calls using

SIP clients

(as WLAN handsets or in

wired or wireless mode on PCs).

The menu comprises the following functions:

Important information:

u

You cannot make calls if there is a power failure,

even the emergency numbers are

not accessible then

.

u

If VoIP is not set up, you will always make calls via the fixed network. The dialling

plans will not apply in this case (page 109).

u

Check these dialling plans (page 109) and change them if you have agreed special

phone tariffs with another provider.

u

Do not change the default setting for the Internet connection mode (= "permanent

connection") if you are using VoIP (page 46). You can only be called via VoIP if this

setting is used. Remember, though, that this setting can result in high connection

costs if you have agreed a time-based tariff with your Internet service provider.

VoIP

Enter the basic data from your service provider here (page 102).

Extensions

Set up the functions for internal extensions here (page 105).

Dialing Plans

Specify numbers here that are to be dialled only via the fixed network

or only via the Internet. You can also enter a call-by-call provider for the

fixed network (page 109).

Define an area code (page 109).

Quick Dial

Specify speed dial numbers or names here for phone numbers you use

frequently (see page 111)

Note:

If you do not specify any of your own dialling plans, then the default settings will be

used as entered in the

Telephony

menu under

Dialing Plans

. Emergency numbers

are directed via the fixed network, while all other calls are made via the Internet.

On

if you wish to use Internet telephony (default setting).

ì

If you have defined more than one

Connection service

(see page 64), choose from

the list the

Connection service

, for which you want configure a VoiP account.

ì

If you have already configured Internet telephony in the

Basic Setup Wizard

, your

VoIP account will be shown with

User name

If you want to configure additional

VoIP accounts

, click

Add

(page 104).

If you have configured VoIP settings in the Basic Setup Wizard the data for your VoIP

account is shown in this line. You can edit this data or add new data for additional

accounts.

ì

You can generally accept the default settings for

Voice Quality

:

–

Maximum upstream bandwidth

: The upstream transmission rate (upstream

bandwidth) varies depending on the provider and DSL tariff and is normally much

lower than the transmission rate for downstream data traffic. If there is upstream

data traffic at the same time over the DSL line, the voice quality may not be opti-

mum. To ensure optimum voice quality, you can use this option to define the

bandwidth, which is to be used as a maximum for your VoIP connection. The

upstream bandwidth is set automatically by default.

To define a fixed upstream bandwidth choose

Fixed

from the

Maximum

upstream bandwidth

option menu and enter the desired value.

The default value is 1000 kbit/s and should suffice under normal circumstances.

You can change these values if necessary, but you have to find out first how high

your upstream transmission rate is. Most providers supply tools for administering

your DSL connection, which should tell you this information. Otherwise, you will

find plenty of Web sites on the Internet that provide such tools.

Enter a value for

Maximum upstream bandwidth

, which is 90 percent of your

available bandwidth.

–

Voice activity detection

: If this function is activated, no data will be transmitted

during breaks in speech during a telephone call.

–

Echo canceller delay

: If you hear your own voice as an echo during VoIP tele-

phone calls, you should choose a different value from the list.

–

Fixed gain control (input/output)

: To adjust the volume for call input (hear) or

output (speak), simply enter a different value.

The value range is -24 to +24.

The higher the value, the higher the volume.

The real value range which can be used depends on your device. If you enter a

wrong value, a message with the valid value range will be displayed.

Extensions

Your Gigaset SX763 WLAN dsl allows you to configure up to six internal extensions that

you can use for making calls via the fixed network or via VoIP. Two of these extensions

are connected to your Gigaset SX763 WLAN dsl via the Phone 1 and Phone 2 ports, while

the remaining extensions are connections for SIP clients. You can assign each extension

the relevant line (fixed network or VoIP account) for incoming and outgoing calls and

make other settings for each extension (e.g. call waiting, call forwarding, caller display).

The process for configuring extensions, which use the two telephone ports of the

Gigaset SX763 WLAN dsl, is somewhat different to that for the SIP extensions. The latter

must be VoIP telephones, which are connected in wired or wireless mode to the Gigaset

SX763 WLAN dsl, or PCs with a SIP client, which are connected to the Gigaset SX763

WLAN dsl.
