SIP Telephony
The SIP Internet (Session Initiation Protocol) protocol provides you with a low-cost,
standardised option for telephoning via IP-based networks. The OpenCom 130 /
150 enables you to use external SIP telephone connections (“SIP trunk lines”). Fur-
thermore, internal SIP subscribers, SIP telephones or SIP telephony software are
also supported (see also

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 an 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.
