Messaging/Paging Functionality
CA50 development and integration tools offer an optional server API that provides methods by which an
application developer can generate various types of messages that can be sent to a CA50 from the server.
•
Text message - the device displays text to the user.
•
Text message with device based audio - the device displays text and plays the specified audio file (.wav file
preloaded onto the device).
For additional information on messaging see pages
Walkie-Talkie (Multicast) Functionality
Walkie-talkie communication is a one-to-many (multicast), half duplex, group communication mode that utilizes the
wireless infrastructure of the facility to communicate within the four walls of the facility.
For example, an associate carrying a CA50 can press the Walkie-Talkie key and instantaneously communicate to
a group associates carrying CA50s. While the first associate talks, the remaining associates carrying CA50s
cannot respond until the first associate releases the Walkie-Talkie key.
For additional information on walkie-talkie communications see
Voice Call (Unicast) Functionality
A voice (unicast) call is a one-to-one full duplex communication mode that utilizes the wireless infrastructure of the
facility to communicate within the four walls of the facility.
For example, an associate carrying a CA50 can select another associate to call from a phone book and carry on a
full duplex, two way conversation with the second associate.
When a CA50 communicates via a voice call without a PBX, there is support for the following voice call
functionality:
•
Initiating a voice call to another CA50 via a UCA server dynamically managed phone book
•
Receiving a voice call from another CA50
•
Placing a voice call on hold and then resuming the call (off hold)
•
Transferring a voice call to another extension (in the absence of PBX, call transfer is supported only in SIP
mode)
For additional information on voice calls see
If an IP PBX is integrated into the CA50 system, there is support for the following additional features:
•
Initiating a voice call to a traditional land line phone via a UCA server dynamically managed phone book
•
Receiving a switch board routed phone call from a customer
•
Receiving a voice call from an in-building land line
•
Transferring a voice call to another extension or a PSTN number via PBX using dynamically managed phone
book. For additional information on IP PBX see
•
Parking a voice call on the PBX for pick up by another user using CA50 menu options
