Please Note:
It is recommended to use a piece of music not longer than one minute in order to leave enough space for user defined
messages and voice mails.

Extension Codecs
To establish IP voice communication, both partners have to use the same codec. When establishing the communication line, this codec is
negotiated. If the caller does not find an appropriate codec, the communication cannot take place. If you want to be reachable by all IP calls, it is
helpful to support as many codecs as possible. In this case, all the codecs that Quadro offers should be added to the
Codecs
table. Some codecs
require a high transfer rate of up to 64 kbit/s. If you are certain you do not want to use these codecs, make sure they are not listed in the table
Codecs
.
The
Extension Codecs
page displays a list of
Codecs
with the
state of the
Out of Band DTMF
and
FAX Support
features for
Quadro extensions and the Auto Attendant.
Please Note:
Use caution when configuring Auto Attendant
Codecs as they are used by virtual extensions for redirecting the
incoming calls.
The table
Codecs
lists active voice codecs for the selected line
that are supported by Quadro. The order of records in the
Active
Codecs
table is important for transmitting and receiving. A codec
placed at the top of the table will be used as the preferred codec.
If the remote party does not support the preferred codec, the
following codecs will be tried in a top to down order in the
Codecs
table.
Each record in the table has an assigned checkbox. They are
used to select the record to be deleted or moved up or down.
An error occurs if no records are selected and the user activates
the delete button, the
“No records selected” error message
appears. At least one codec must be attached to the line. When
attempting to delete the last codec, the “At least one codec
should stay in the codec list” error message will appear.
Enable/Disable
functional button is used to enable or disabled
the corresponding codec for the extension. When the codec is
disabled, the extension user will not be able to use it for placing
a call.
The
Move Up/Move Down
buttons are used to move the
selected codec one level up/down in the table.
Make preferred
moves the selected codec to the top of the
table, setting its priority to the highest. Clicking the
Make
preferred
button when a disabled codec is selected will first
enable the codec and then move it to the top.

The
Out of Band DTMF
Transport
checkbox enables DTMF code transmission in parallel with the voice stream. The destination receiving the
DTMF code will play it locally if it supports the feature. This is helpful to avoid DTMF’s loss upon bad traffic. This feature is valuable for all codecs but
it is especially recommended to enable it in case low bit rate codecs (G.729, G.726/16, etc.) are selected.
Enable T.38 FAX
checkbox enables the FAX tone detection and the T.38 codec support for the FAX transmission from/to the FAX machine/modem
attached to the line. It also enables the T.38 codec support for incoming unified FAX messages.
The
Enable Pass Through FAX
checkbox enables the FAX tone detection and the G.711 codec support for the FAX transmission from/to the FAX
machine/modem attached to the line. It also enables the G.711 codec support for incoming unified FAX messages.
If both of the above checkboxes are enabled, the T.38 codec will be used as a preferred codec for FAX transmission. If it is not supported by the
peer, the G.711 codec will be used instead. If the extension is attached to the line that has no FAX machine/modem connected (the extension is
virtual or is attached to an IP line), the incoming FAX can only be stored in the extension's voice mailbox. To allow FAX to be stored in the voice
mailbox, the extension's user should not answer the incoming calls, so that they are forwarded to the voice mailbox.
Please Note:
If both of the above checkboxes are disabled, no FAX transmission to the peer's voice mailbox will be possible.
Enable Pass Through
Modem
checkbox is only available for Auto Attendant and extensions attached to the FXS lines (it is not available for extensions attached to the IP
