SIP Telephony
The SIP Internet (Session Initiation Protocol) protocol provides you with a low-
cost, standardised option for telephoning via IP-based networks. The
Forum 523/524 enables you to use external SIP telephone connections (“SIP
trunk lines”). The Forum 523/524 communications system supports configu-
ration of standard SIP lines with one call number for each as well as
extension-capable SIP-DDI lines with base call number and extension.
Furthermore, internal SIP subscribers, SIP telephones or SIP telephony
software are also supported (see also

Route
menu gives you the option to configure a
bundle overflow, which automatically occupies a second line in case of a
breakdown or over-occupancy of the SIP connection. You can also set up your
system to route certain types of calls, such as international calls, to a SIP
connection.
Note:
You will need a Media Gateway card for SIP telephony.
You will also need a fast Internet connection such as DSL for SIP telephony.
You will also usually need the services of a SIP provider. A SIP provider
operates a special server (the SIP Registrar) to handle connections. The SIP
provider also operates a gateway to the ordinary telephone network which
