Setting Up Internet Telephony (Voip) - Gigaset SX763 Manual

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
wired or wireless mode on PCs).
The menu comprises the following functions:

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.
Important information:
You cannot make calls if there is a power failure, even the emergency numbers are
u
not accessible then.
If VoIP is not set up, you will always make calls via the fixed network. The dialling
u
plans will not apply in this case (page 105).
Check these dialling plans (page 105) and change them if you have agreed special
u
phone tariffs with another provider.
Do not change the default setting for the Internet connection mode (= "permanent
u
connection") if you are using VoIP (page 42). 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.
