Voice quality and infrastructure
A Gigaset C470 IP or C475 IP will allow you to make calls with good voice quality via the
Internet.
However, your phone's performance with VoIP – and therefore the voice quality – also
depends on the properties of the entire infrastructure.
The following VoIP provider components are just some of the things that can influence per-
formance :
u Router
u DSLAM
u DSL transmission line and speed
u Connection paths over the Internet
u If necessary, other applications that also use the DSL connection
In VoIP networks, voice quality is affected by various things including the "quality of serv-
ice" (QoS). If the entire infrastructure demonstrates QoS, voice quality is better (fewer
delays, less echoing, less crackling etc.).
If, for example, the router does not have QoS, then the voice quality is not as good. Please
see the specialist documentation for further information.
Assigning send and receive numbers to handsets
You can assign up to eight numbers on your phone: your fixed line network number, your
Gigaset.net number and six VoIP numbers.
You can assign as many of these numbers as you like to each handset as receive numbers.
Receive numbers determine which handset(s) will ring when a call is received.
You can assign one of your VoIP numbers to each handset as a (VoIP) send number. Send
numbers define which VoIP account should be used in general to make and pay for outgo-
ing VoIP calls. Exceptions:
u a phone number is dialled with a line suffix (page 121) or
u a dialling plan has been defined for the phone number (page 135).
The Gigaset.net number and fixed line network number are permanently assigned to each
registered handset as send numbers.
Please note:
You should observe the following for good voice quality:
– When making calls using VoIP, avoid performing other Internet activities (e.g. surfing the Inter-
net).
– Irrespective of the codec used and the network capacity utilisation, please note that voice delays
can occur.
Please note:
A handset is assigned the following numbers after it is registered on the base station:
– Receive numbers: all phone numbers assigned to the phone (fixed line network, Gigaset.net and
VoIP).
– Send numbers: the fixed line network number and the VoIP phone number that you entered at the
start of the phone configuration.
