VoIP Installation
You can install a DSX IP Keyset on-premise in a managed network or as a remote IP extension. The DSX IP Keyset supports common CODECs (G.711A, G.729, and G.722) which let you easily balance voice quality with available bandwidth.
Setting up DSX Remote IP Keysets using NAT Traversal requires the purchase of a Linksys WRT54GL or WRT160NL router for each remote site. Additionally, port 5060 at the system-side router must be forwarded to the system IP address. Depending on your experience level, this may require the services of an IT professional.
If setting up DSX Remote IP Keysets using VPN (Virtual Private Network), it requires the purchase of third-party VPN routers and the services of an IT professional.
For a complete index of the available VoIP resources, click VoIP Extensions in the menu bar at the top of this page.
The DSX IP Keyset uses a single CAT5 ethernet cable to the desktop which connects to the compact, 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.

Third Party SIP Extensions
Third party SIP extensions compliant with SIP VoIP RFC 3261 can be installed on-site or remotely. The SIP extension should provide all the features available at a single line telephone unless dial pad keys are "hijacked" by the SIP extension. For example, if a SIP extension uses * as a setup command, it won't be able to use Directed Call Pickup.
Emergency (911) Calls and Remote IP Extensions
When a remote IP extension user dials 911, the call routes to the 911 service for the location in which the main system is installed. The emergency call does not route to the 911 service for the remote location.
