Providers and PBXs
In a local network (LAN), the telephone can operate as an Auerswald VoIP system telephone
and/or as a standard VoIP telephone.
Provider
A VoIP provider is an Internet service provider that offers Internet telephony (VoIP, meaning
"Voice over Internet Protocol").
There are many providers that issue each customer their own telephone number, which can be
called from a land line, as well as over the Internet. Depending on the provider used, and the
telephone number called, these types of telephone connections may extremely cheap, if not
free of charge.
Some providers give the impression that Internet telephony is totally free of charge. However,
it is important to research the actual costs incurred by checking the tariff tables of the particular
provider. As the connection to a land line connection is established over a gateway, the location
of the gateway may affect any charges associated with the call. This applies especially to inter-
national calls that may be more expensive than simple calls on a public switched network if the
gateway is located domestically.
PBXs
PBXs connect different internal end devices with different public telecoms networks, enabling
users to make external and internal calls. The PBXs make different ports/interfaces available
for this.
