Call Park Service - Bizfon 2000 Administrator's Manual

Bizfon Manual II: Administrator's Guide
The Extension Codecs page displays a list of Codecs with the
state of the Out of Band DTMF and FAX Support features for
Bizfon 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 Bizfon. The order of records in the 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.
Please Note: G.723 codec support is limited on the Bizfon per default. To enable it, insert the feature key in the
4 simultaneous G.723 calls can be handled on the Bizfon.
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 is only available for extensions attached to the FXS lines (it is not available for extensions attached to the IP line). This
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. The Enable Pass Through FAX checkbox is only available for extensions attached to the FXS lines (it is not available for extensions attached
to the IP line). This 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 is only available for extensions attached to the FXS lines (it is not available for extensions attached to the
IP line). This 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
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.

Call Park Service

Call Park service is 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 to place the call at a specific number and then retrieve when they reach the conference room.
To use the Call Park feature, the call parking service should be enabled for one or more extensions on the Bizfon from the
page.
To activate the Call Park service, the Bizfon user should dial the appropriate digit combination (see Feature Codes) during the call. The destination
party will be placed on hold, while the SIP username of the first available extension is being configured for the call parking (if the extension is
registered on the SIP server). The extension's PBX number, will be played to the Bizfon user. The Call Parking is valid for 15 minutes. During this
time hold music (if configured) will be played to the parked destination party. When the Call Park timeout expires, the phone initiating the call parking
will start to ring. If no one picks up the parked call, or if the phone is off hook, the parked destination party will be automatically disconnected.
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. Both PBX and IP
calls are allowed. For PBX calls, the extension number should be dialed. For IP calls, the SIP address is played by the Bizfon when activating the
Call Park service, if it is routed to the corresponding extension. The pickup user will be prompted to pass the authentication by inserting the
password of the Bizfon user (where the call has been parked) in order to retrieve the parked call.
For example, the Call Park service is enabled for extension 23, which has been registered on the SIP Server under the 892220 registration
username. While being on a call with user A, the Bizfon user dials the appropriate calling code. As a reply, Bizfon will play the 892220 to the Bizfon
Bizfon2000 and Bizfon4000 (SW Version 4.1.x)
RTP Settings) and Echo Cancellation are being disabled on the line.
