Features and Benefits

• Integrated telephone, microphone, battery feed, and power ringer provides a convenient, complete, and easy-to-use development tool for recording prompts and testing voice applications and eliminates the need to buy additional equipment for testing and prompt recording
• Amplified electret microphone with high/low/off audio sensitivity switch provides superior quality over standard tele-phone carbon microphones
• DTMF keypad provides DTMF tones for command input
• Audio input/output jacks connect easily to and from external, standard audio sources
• Handset enables monitoring of audio from an external source without affecting recording
• Simulates central office "battery" for loop current by connecting to and powering telephony loop start interface
• Supplies ring voltage to simulate ring signal for initiating a voice recording or testing an application

 

• Interactive voice response
• Audiotex
• Inbound and outbound telemarketing
• Voice mail/voice messaging

 You can record voice prompts through the PromptMaster handset, generate DTMF tones using the keypad, or push a button to send a ring voltage to the voice board line interface. The three-position handset switch lets you record at a normal volume, boost the volume, or silently monitor recording or playback.

 Since the PromptMaster uses a wall-mounted power supply, it also provides loop current for direct connection to the voice board, thus eliminating the need for an external connection to the central office during application development. Additional input and output jacks let you load prerecorded prompts into your system using standard audio sources, or you can play back your application to external sources like a cassette tape recorder.

 You can also use the PromptMaster for recording application prompts after testing. The PromptMaster incorporates an amplified elec-tret microphone that provides better reproduction quality than the standard carbon microphones found in most telephones. It is an excellent choice when recording prompts in end-user applications where prompts need to be updated frequently and professionally recorded prompts would be too cost prohibitive.

 Operation
 To record prompts to a voice board using the handset, your typical application waits for ring, goes off hook on the appropriate channel, then records prompts using DTMF digits to control file recording, playback, and other operations. To record these prompts using the PromptMaster, pick up the handset and briefly press the RING button. Your application responds by going off hook and initiating the record function. An indicator on the front of the PromptMaster telephone lights when both the PromptMaster and the voice channel are off hook. This indicates that loop current is flowing. Now you can record your prompts by speaking directly into the handset.

 To record your voice prompts using an external source such as a cassette tape recorder, connect your external source to the PromptMaster telephone via a standard MONO miniplug. To start recording, pick up the handset and briefly press the RING button. Your application responds by going off hook and initiating the record function. You can now record your prompts directly from your external source.

 The PromptMaster is manufactured for Dialogic by Sound America of Savannah, Georgia, a leading manufacturer of audio equipment for the broadcasting industry for over twelve years.
