Advanced Settings for SLA# Help

The Advanced Settings for SLA# page is used to configure the Unconditional or No Answer Call Forwarding and the Hold Music Settings for each. When the forwarding is enabled, all incoming calls to the corresponding SLA line will be redirected to the defined destination. If the call forwarding is activated, the programmable key assigned to the corresponding SLA line will remain in the ON state until the call is disconnected.

The following ways of Call Forwarding are available for the SLA lines:

Unconditional - all incoming calls to the corresponding SLA line will be forwarded to the specified destinations.
No Answer - incoming calls will be forwarded to the specified destinations if the corresponding SLA line is not answered within 20 seconds.

The Enable Service checkbox selection on the related page activates corresponding call forwarding service on the current SLA line.

Attention: The following rules are applicable to all call forwarding types:

PSTN destinations (with PSTN or Auto call type) have priority in Forward to list. If there are different destinations in the Forward to list, the call will be forwarded to PSTN destination (in the same time any available SIP or PBX destinations will receive a short ring). If the PSTN destination was not successful, the next PSTN destination will be dialed, otherwise if there are no more PSTN destinations in the table, the call will be forwarded to any available SIP and PBX destinations simultaneously.
If there are multiple entries with any combination of PBX or SIP call types, then all destinations will ring simultaneously and the call will be established with the destination that will pick up the call the first.
Unconditional Call Forwarding service has higher priority versus to other forwarding types, i.e. when Unconditional Call Forwarding is enabled, No Answer Forwarding services will not work even if they are enabled.

The table displayed in each page of Call Forwarding configuration lists the destinations where incoming calls addressed to the corresponding SLA line will be forwarded.

Enable/Disable functional button is used to enable/disable the corresponding forwarding destinations. This is helpful to avoid removing forwarding destination(s) if they are not applicable at the moment.
Add opens a Add Entry page where a new forwarding destination may be specified by its Call Type (PBX, SIP, PSTN or Auto) and depending on this call type, by its extension number, SIP address or PSTN number in the Forward to text field. Only a SIP registration username can be inserted here to forward calls to the user registered at the same SIP server as the current extension is registered at, i.e. if the SIP server hostname is left empty, the system will automatically set the current extension's registration server hostname. The extension number should be inserted in the Forward to text field for the PBX call type. The PSTN number length depends on the area code and phone number. When Auto is selected as a Call Type, routing pattern will be considered here and parsed through Call Routing Table.
The SIP-Clipboard button at the end of the line can be used only when SIP is selected in the Call Type drop down list. It opens a small window where one of the previously entered 10 SIP addresses can be automatically selected again. If the address already exists in the table, selecting Save will cause the error "Caller address already exists". Wildcard is allowed in this field.

Note: System allows to forward incoming calls to the Quadro PSTN lines, thus giving callers a possibility to make calls through remote Quadro's PSTN lines. To do so, select PSTN from the Call Type drop down list and type pstn (capital and lower case letters allowed) in the Forward to text field. Caller will connect to the available PSTN line, get the dial tone and be free to dial the PSTN number.

Attention: By default all PSTN lines on the Quadro are assigned to the SLA lines. If you wish to forward the incoming call to the PSTN network, detach at least one of the PSTN lines from the SLA line.
Edit opens the Edit Entry page where a forwarding destination can be modified. This page has the same components as Add Entry page does.
Delete removes the selected "Forward-to" address(es) from the forwarding list.
Select all checks all existing table entries.
Inverse Selection inverses the current selection (if no records are selected, clicking on inverse selection will check all records).

The Hold Music Settings are used to define the music that will be played when being on hold or putting a remote party on hold. To specify this music the following checkboxes and text fields are available:

Send Hold Music to Remote IP Party enables the specified music for sending to a remote IP party whenever it is on hold and waiting. If this checkbox is disabled, Quadro will not send any hold music to the remote IP party. The remote IP party will then hear their own hold music, or something similar, if configured. The hold music is always sent to PBX and PSTN destinations independent on the configuration of this option.

The Listen Hold Music drop down list specifies the music current user will hear when being on hold. It offers the following options:

Off - no music will be played.
Own Music - the current user will define the music that will be played to them self while being on hold.
Remote Party's Music - the current user will hear the remote party's hold music, if enabled, and sent by remote party.

The manipulation radio buttons group allows you to select the way custom hold music will be provided.

File selection is used to upload the hold music file. The following options are available under this selection:

Restore Default Hold Music File enables the default music. If the checkbox is selected, the text field Upload New Hold Music File will be disabled.

Upload New Hold Music File text field can be used to type the path where hold music file is located. If hold music file is browsed with the help of file-chooser, this field displays the path of the browsed file. Browse button is used to browse for the hold music file.

The music file needs to be in PCMU (CCITT u-law, 8 kHz, 8 bit Mono) wave format, otherwise the system will prevent uploading the file and display the warning message "Invalid audio file or format is not supported". The system will refuse uploading also if there is not enough memory available for the corresponding extension and will then announce "You do not have enough space".

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.

The Download Hold Music File link appears only if a file has been uploaded recently. It downloads the audio file to the PC and opens a window where the saving location can be specified.

RTP Channel selection is used to define the channel for the broadcast streaming. The RTP channels are created by the system administrator. Therefore if you are experiencing problems with using the RTP channels as hold music, or no RTP channels are available to select on this page, turn to your system administrator for clarification.
