Hook-Flash or press the
Flash
button to switch between calls.

When the device Phone port goes On-Hook, this ends the current call and invokes a ring for the
holding call. The device Phone port supports 3-way Calling when the second call is an outbound call.
On the first Hook-Flash during an active call, the device can make a second outbound call.
On the second Hook-Flash, the first call and the second outbound call are placed in a conference. To remove
the second conferenced party, invoke a third Hook-Flash.
When the device goes On-Hook during a 3-way Call, this becomes a transfer when the second (outbound)
call is ringing or connected. If the second call doesn’t succeed, then the Phone port goes to an On Hook
state and rings as the holding call is still on the line, or Hook-Flash to resume the first call.
The device Phone port can select from the following services to which it can complete a call:
●
SP1 Service (SP1)
●
SP2 Service (SP2)
●
SP3 Service (SP3)
●
SP4 Service (SP4)

Available Features
The HDA50 supports many IP routing and LAN features.
IP Routing and LAN Switching Features
The HDA50 has two Ethernet ports labeled as the Internet port and the LAN port. The device works as a
router by default. All the native voice services and features use the WAN port only when the HDA50 is in
router mode. To use the device as a 3-port switch (in Bridge mode) change its
OperationMode
parameter
from
Router
to
Bridge
. One of the switch ports is for internal use only.
IP Routing Features
In router mode, the network connected to the Internet Port is the WAN side of the device, and the network
connected to the LAN Port is the LAN side. You can connect the WAN side to another Ethernet switch or
directory to an access device, such as a modem. The HDA50 routes traffic between the LAN side and the
WAN side, allowing devices (such as PCs) attached to the LAN side to share Internet access. The HDA50
supports subnet masks as large as 255.255.255.0 to accommodate as many as 253 IP addresses on its
LAN side subnet.
