Telco Troubleshooting; Ethernet - Polycom SoundStructure C16 Design Manual

If I Mute On The SoundStructure, Why Doesn't The Mute Icon Appear On The Video
Codec?
As described in Connecting Over Conference Link2, mute commands from the Polycom Video Codec send
commands to the SoundStructure device and adjust mute status of the "Mics" virtual channel group within
the SoundStructure system. If the mute status of the "Mics" group is adjusted independently on the
SoundStructure system, a command is not sent to the Polycom Video Codec and consequently the Polycom
Video Codec will not update the mute status on the screen.
If using a control system to change the local global mute status in the system, have the control system adjust
the mute state on the Video Codec system and the SoundStructure mute state for the "Mics" group will track
to that state.

Telco Troubleshooting

Phone Won't Go Off Hook Or I Don't Hear Dial Tone
Check that the phone line from the PBX or central office is plugged into the LINE port on the rear of the
SoundStructure device.
Use SoundStructure Studio and from the Channels Page select the phone Settings... button to open a
telephone keypad. Click the handset icon to take the phone off hook.
Check that the virtual channel name used for the telephone channel matches the name used within
SoundStructure Studio to create the telephone channel.
Check that you are able to control other aspects of the system such as muting microphones or routing the
signal generator through the loudspeaker system.
Phone Won't Auto Hang Up
Depending on the revision of the firmware, the SoundStructure device supports auto hang-up from either
loop drop detection or call progress detection.
Loop drop detection happens when the central office or the local PBX indicates the remote caller has
hang-up by interrupting the loop current or reversing the polarity. Loop drop detection is not always
supported by PBX's.
Call progress detection happens when a busy or fast busy tone is detected as an input signal from the
telephone line. The tones are typically generated by the central office or by the local PBX after some period
of time after the remote phone participant has hung up.
I Dial But I Don't Hear The Digits
In SoundStructure, the phone must be taken offhook before the digits will be sent to the telephone interface.
In Vortex the phone would go offhook automatically when digits were dialed, but in SoundStructure the
phone_connect command must be explicitly sent to take the phone offhook before dialing.

How Do I Determine The IP Address Of My SoundStructure Device?
By default the SoundStructure device has DHCP enabled and will accept an IP address from a DHCP
server. A static IP address may also be configured for the SoundStructure device.
