Setting up Internet telephony (VoIP)
The Giga762SX 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 Giga762SX 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 106).
u
Check these dialling plans (page 106) 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 44). 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.
Note:
u
WDS can only be used with WEP encryption or without encryption. You may have to
change the encryption of your wireless network, if applicable.
u
The encryption settings on the repeater have to correspond to the settings on your
Giga762SX WLAN dsl.
u
The Giga762SX WLAN dsl and the repeaters must use the same channel.
Further information can be found in the user manual for the repeater.

fixed network (page 106).
Define an area code (page 106).
Quick Dial
Specify speed dial numbers or names here for phone numbers you use
frequently (see page 107)
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.

Extensions
Your Giga762SX 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 Giga762SX 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
Giga762SX 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
Giga762SX WLAN dsl, or PCs with a SIP client, which are connected to the Giga762SX
WLAN dsl.
