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. For virtual extensions, 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 available for the Auto Attendant and the extensions attached to the FXS lines only. This checkbox
enables the modem tone detection and the G.711 codec support for the data transmission from/to the modem attached to the line. During data
transmission,
Silence Suppression and Echo Cancellation are automatically disabled on the line.
Please Note: If the extension/attendant is intended to accept modem connections, disable the Enable T.38 FAX checkbox to allow the system to
identify the modem tones correctly. Otherwise, the modem connection may fail.
Force Self Codecs Preference for Inbound Calls checkbox enables the usage of your own preferred codecs (if available on both peers).
Secure RTP Settings are used to configure secure voice over IP communication on the Quadro. The SRTP Policy drop down list is used to select
the secure IP connection policy. For IP phones, the following options are available:
• Make and accept only secure calls - only the secure calls will be generated and accepted.
• Make and accept only unsecure calls - only the unsecure calls will be generated and accepted.
• Try to establish secure calls, accept anything - system will try first to establish secure call, but will fallback to unsecure call if party
doesn't accept secure calls; both secure and unsecure incoming calls will be accepted, as requested by remote party, with the preference
given to establishing secure call.
• Make unsecure calls, accept anything - system will establish unsecure outgoing calls, but both secure and unsecure incoming calls will
be accepted as requested by remote party.
For bandwidth used by secure calls, see
Needed Bandwidth for IP Calls.
Call Park and Directed Call Park Service
The Call Park and Directed Call Park services are used to store a call on a specific number so that any other user on the system can retrieve it. For
example, a user receives a call but wants to take it in a conference room where it is possible to speak privately. Transferring the call to the
conference room is not an option because the conference room it is transferred to might be in use, or the user is unable to walk to the conference
room in time to answer the call. The user can use Call Park and Directed Call Park to place the call at a specific number and then retrieve when
they reach the conference room.
To use the Call Park or the Directed Call Park features, at least one Call Park extension should be created in the
Extensions Management table.
Additionally, two lists should be defined for the call park extension: Park Access List for users that might park a call to the corresponding Call Park
extension and Retrieve Access List for the users that can pick up calls parked to that extension. By default, both of these lists have entries so any
PBX extension on the Quadro can park the call, and any destination can retrieve the parked call. Any limitations to these settings should be done
individually for each call park extension.
To make a Call Park
To make a Call Park, the Quadro user which has been previously added to the Park Access List for at least one of the available Call Park extension
on the Quadro should dial the appropriate digit combination (see Feature Codes in Manual III - Extension User’s Guide) during the call. The active
call will go on hold, while the PBX number and the SIP username (if it is registered on the SIP server) of the first available call park extension where
the user is added will be played to him/her.
The pickup user will be able to pick up the parked call from any destination by calling the extension where the call has been parked (either by its PBX
number or SIP address). The authentication password will be prompted (if configured) of the call park extension in order to retrieve the parked call.
For example, the Call Park extension 77 is created which has been registered on the SIP Server under the 892220 registration username. The
Quadro user is added to the Park Access List, while the phone at the remote location is added to the Park Access List of that call park extension.
While being on a call with user A, the Quadro user dials the appropriate calling code. As a reply, Quadro will play the extension 77 and SIP
username 892220 to the Quadro user. The user A goes on hold. The Quadro user moves to a remote location and makes a call to the call park
extension. The Quadro user enters call park extension's password and resumes the conversation with user A.
To make a Directed Call Park
To make a Directed Call Park, the Quadro user, which has been previously added to the Park Access List for at least one of the available Call Park
extension on the Quadro, should place the current call on hold and then dial the Call Park extension number within the five second timeout (see
Feature Codes in Manual III - Extension User’s Guide).
Attention: If the five second timeout is exceeded, then the Quadro will consider it as an attempt for retrieving the parked call.
The Call Park extensions can be mapped directly to IP phones or simply announced via paging through the IP phones or analog paging system.
Calls can be easily parked by placing the current call on hold and then pressing the park button followed by the desired extension. This can be
further simplified if the desired Call Park extension is already mapped to the phone, then the user will just press that specific park key and the call will
automatically be parked to that extension.
The pickup user will be able to pick up the parked call from any destination by calling the extension where the call has been parked (either by its PBX
number or SIP address). The authentication password will be prompted (if configured) of the call park extension in order to retrieve the parked call.
