202 CHAPTER 3: DEVICE CONFIGURATION
Silence Suppression Enables the Silence Suppression feature, which reduces
network traffic by replacing a period of silence with a
small silence indicator packet.
Call Record & Monitor Determines whether calls made to or from the telephone
attached to this ATA can be recorded.
Enabled — Enables recording for all calls to or from the
analog telephone attached to this ATA or ATC port.
Disabled — Disables recording for all calls to or from the
analog telephone attached to this ATA or ATC port.
Fwd to Auto Attendant Redirects unanswered calls to the Auto Attendant instead
of voice mail.
Extension Number The extension number assigned to the device connected
to this ATA.
First Name, Last Name,
Title, Location 1,
Location 2, Department
Enter information about the user associated with the
device connected to this ATA.
Location 1 and Location 2 enable you to provide detailed
information about the location of the ATA (required for
E911 (Enhanced 911) emergency service).
Low Bandwidth Configures the device to operate over a low-bandwidth
link such as an ISDN connection. Some features not
available to a low-bandwidth device: paging,
conferencing, and Music-on-Hold.
Do not enable low bandwidth for a device that is
connected through a broadband connection through a
router/firewall device on the remote end.
ADPCM Audio Only Restricts the ATA to support ADPCM audio only.
NOTE: If you are connecting a fax device, do not select
this option. Fax requires Mulaw audio.
Conference Disabled Prevents this device from being used for conference calls.
Fax Machine Alerts the PSTN that voice data must be uncompressed.
Check this box when sending or receiving faxes over
ISDN PRI lines.
CAUTION: Configuring an ATA device (either a single-port analog terminal adapter
or a port on an analog terminal card) for fax operation optimizes the performance
for inbound and outbound faxes. If you make a voice call using the ATA device (for
example, if you use the telephone portion of the fax machine), the quality of the
audio may be affected. If you make a VTL call using the ATA device, the audio may
be unusable. If you configure the port for fax operation, expect lower quality voice
calls on that port. If you configure the port for voice calls, the performance is not
optimized for faxes.
