Solution
Ensure the desired virtual channel name
is spelled properly and the command
syntax is correct as described in the
SoundStructure Command Reference
document.
Check that the loop current and line
voltage are shown on the phone settings
screen and that they change when the
phone is taken off-hook.
Check that the telco channel is unmuted
and routed properly through the
SoundStructure matrix to the amplifiers
that are driving audio into the local room.
Check that the local room amplifiers are
connected to the correct physical output
channels on the SoundStructure device as
confirmed on the wiring page within
SoundStructure Studio.
