QuadroISDN; SW Version 4.1.x 37

Add opens the Add Entry page where the user may add

codecs supported by Quadro. The voice codec defines the

voice compression algorithm for the incoming and outgoing

DSP packages.

Codecs lists all codecs supported by Quadro. If no more

codecs are available (all available codecs have already

been transferred to the Active Codecs table), the Add

Entry page will display the message “No Available Codecs”

instead of the drop down menu.

The Move Up/Move Down buttons are used to move the selected codec one level up/down in the table.

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 (G729, G723, G726/16, 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/Fax

modem attached to the line. Enable Pass Through FAX checkbox enables the FAX tone detection and the G711 codec support for the FAX

transmission from/to the Fax Machine/Fax modem attached to the line.

If both of these checkboxes are enabled, T.38 codec will be used as preferred codec for FAX transmit/receive and if not acceptable by the peer,

G711 codec will be used instead.

Please Note: If both of these checkboxes are disabled, no FAX transmission to the peer’s voice mailbox will be possible. Checkboxes are applicable

for FAX transmission/receipt over an IP network only.

Enable Pass Through Modem checkbox enables the modem tone detection and the G711 codec support for the data transmission from/to the

modem attached to the line. During data transmission, Silence Suppression (see

RTP Settings) and Echo Cancellation are being disabled on the

line.

The Force Self Codecs Preference for Inbound Calls checkbox enables the usage of your own preferred codecs (if available on both peers) for

the IP connection establishment on the extension.

Authorized Phones Database

The Authorized Phones Database page is used to create a list of trusted external phones. If they are part of the Quadro Authorized Phones

database, external SIP or PSTN, then users are free to access the Quadro Auto Attendant services without requiring authentication. When adding a

trusted phone to the list, an existing extension has to be chosen. The parameters (extension number and password, as well as SIP and Speed

Calling Settings) will be used automatically for the trusted caller access of the Quadro Auto Attendant. A direct connection to the Call Relay menu

can be optionally provided.

The Authorized Phones Database page displays the

Authorized Phones Database table where the trusted phones

are listed. Only SIP and PSTN users can be added to the

Authorized Phones Database.

The Authorized Phones Database table displays all trusted

callers with their settings. For example, the call type, caller

address, extension they automatically login with, information if

they have automatic access to Call Relay Menu of the Auto

Attendant, etc.

Each record in the table has an assigned checkbox. The checkbox is used to edit or delete the corresponding record. The “No records selected”

error message occurs if the user activates the edit or delete button with no records being selected. The error message “One record should be

selected” appears if the user tries to edit more than one record. The heading of each column in the table has a link. By clicking on the column

heading, the table will be sorted by the selected column. When sorting (ascending or descending), arrows will be displayed next to the column

heading.

The Add functional button refers to the Authorized Phones Database- Add Entry page where new trusted users may be entered.
