TroubleShooting
10 - 15
Use SoundStructure Studio and from the Channels Page select the phone Set-
tings... 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 sup-
ports 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 auto-
matically 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.
It is possible to determine the IP address for the system via several methods:
Connect to the SoundStructure device via RS-232, open SoundStructure Studio
and autoscan the device. The IP address will be shown in the Wiring page.
Open DOS shell and ping the network with the broadcast address:
xxx.yyy.zzz.255 and then look for the MAC address in the results generated
from an ‘arp –a’ command. The MAC address of the SoundStructure device is
available from the front of the device inside the front-panel door.
