DSX VoIP requires the installation of a VoIP Gateway Daughter Board (VOIPDB) The VOIPDB provides four IP gateway ports but is expandable through licensing. The system allows up to 8 maximum VoIP gateway ports on DSX-40; 16 maximum on DSX-80/160. You can install only one VOIPDB per system.

The DSX IP Adapter (IPA) connects the DSX IP keyset to the LAN. The DSX IP Keyset uses a single CAT5 Ethernet cable to the desktop which connects to the compact and unobtrusive DSX IP Adaptor. The adaptor connects to the LAN, the IP keyset, and a PC, as well as provide the power required by the telephone. A separate power supply and cable are not required. If the router to which the keyset is connected is Power Over Ethernet (PoE 802.3af) compliant, the DSX IP Adaptor power supply is not required because telephone power can be provided by the router.
