The Key System Emulation page is used to configure and setup the Shared Line Appearance (SLA) lines on the Quadro. The available SLA lines and their configuration parameters are listed in the table on this page.
Pressing on the SLA# link will open the corresponding SLA line settings.
The Key System Emulation - SLA# page is used to configure the corresponding SLA line on the Quadro and contains the following components:
The SLA Name text field is used to insert the preferred name for the corresponding SLA line. On the IP phones with the display available, this name is visible on the display next to the programmable key.
A group of manipulation radio buttons allow to configure the SLA line:
Inactive - disables the corresponding SLA line.
PSTN - allows you to assign the SLA line to the available PSTN lines on the Quadro. This selection disappears when there are no more unassigned PSTN lines available. Attention: By assigning a PSTN line to an SLA line, it becomes unavailable for calls through Auto Attendant or Call Routing Table.
SIP - used to assign the SLA line to the certain SIP account. This selection has two sub-selections:
Custom Settings - used to define a SIP server and SIP registration parameters. The following parameters are required for this selection: Username - the registration username on the SIP server. Password - the registration password on the SIP server. SIP Server - the IP address or the host name of the SIP server. SIP Port - the port of the SIP server. Authentication User Name - an identification parameter to reach the SIP server. It should be provided by the SIP service provider and can be requested for some SIP servers only. For others, the field should be left empty. Outbound Proxy Host Address and Port - the IP address or the host name and the port number of the outbound proxy SIP server. For more details see Extensions Management - SIP Advanced Settings.
Use SLA Settings - choose this selection to use the SIP settings of another SLA line. This selection is also used to allow multiple line appearances on the same ITSP provider. The SLA drop down list is used to select the SLA line whose SIP settings will be used for the corresponding SLA line.
The DID text field requires an optional identification number used by some ITSP providers to differentiate between the call appearances on the selected line.
The Use DID for outgoing calls indicates whether the specified DID number should be included in the Caller ID of calls initiated from the SLA. If this checkbox is enabled, the DID number will be sent along with the SIP username. This checkbox should be enabled if the IP-PSTN provider authorizes the users by their DIDs.
The Forwarding for SLA# links in the Advanced Settings column refer to the Advanced Settings for SLA# page where the unconditional or no answer call forwarding can be configured for each SLA line.
The Advanced Configuration functional link moves to the Key System Advanced Settings page. The Advanced Configuration page is used to enable/disable the blind transfer service from SLA lines to extensions or their voice mailboxes.
The page consists of the following settings:
The Enable blind transfer to VM checkbox indicates whether a call received to an SLA can be blind transferred to extensions’ voice mailboxes. Selecting the checkbox will enable the blind transfer functionality and will require a prefix (digits only) that should precede the calls to voice mailboxes. To call a voice mailbox, the user should dial the specified prefix followed by the extension number.
The Enable blind transfer to extension checkbox indicates whether a call received to an SLA can be blind transferred to extensions. Selecting the checkbox will enable the blind transfer functionality to extensions. You may optionally specify a prefix that should precede the calls to extensions. Specifying a prefix is mandatory if the extension numbers have the same length as the SIP usernames on the SIP server on which the SLA is registered.
Note: If the Enable blind transfer extension checkbox is disabled, all calls initiated from SLAs are routed to the SIP server on which the SLA is registered (if any). If the checkbox is enabled but no prefix is specified, outgoing calls will be routed to the SIP server only if the number of dialed digits does not math the extension length specified on the system.
