Sip Telephony - DETEWE OpenCom 130 User Manual

Voice over IP (VoIP)
■
The MGW interface card contains the required software in its own Flash
memory. This software is updated using a separate file in the Configurator via
the SYS Configuration: Components.
Operational Information
The MGW interface card must be correctly inserted and configured (see also
Installing Interface Cards starting on page 29).
Each MGW interface card requires its own IP address. This can either be assigned
statically or obtained via DHCP.
1. In the Configurator, open the PBX Configuration: Ports: Slots page.
2. Click on the slot number in the table column containing the desired interface
card.
3. Enter the desired static IP address in the IP address configured field. Enter
"0.0.0.0" to obtain an IP address via DHCP.
4. Confirm with Apply.
The configuration page displays the MGW interface card's MAC address. You will
need this for the static assignment of an IP address via a DHCP server.

SIP Telephony

The SIP Internet (Session Initiation Protocol) protocol provides you with a low-cost,
standardised option for telephoning via the Internet. OpenCom 100 enables you
to use external SIP telephone connections (SIP trunk lines). The PBX Configu-
ration: Trunks: Route menu gives you the option of making an SIP connection on
a normal ISDN line in case of bundle overflow, breakdown or over-occupancy. You
can also set up your system to route certain types of calls, such as international
calls, to an SIP connection.
You will also need a fast Internet connection such as DSL for SIP telephony.
Note: During the commissioning of a MGW interface card,
the software MGW function is automatically switched off.
Note: You will need a Media Gateway card for SIP telephony.
