Intercoms with Pre-Recorded Audio Messaging

Enhancing Communication, Safety and Accessibility

Today’s intercom systems allow much more than just two-way talk. The most useful advancement in recent years is the ability to play pre-recorded audio messages that automatically play at specific call events. Intercoms can now provide added guidance, information and reassurance with hands-free automated voice prompts. Modern systems are fully programmable to meet the needs of every type of environment, including building entrances, industrial facilities and elevators.

How it Works 

An intercom system with pre-recorded audio messaging support can automatically play programmable local messages at specific defined call events. Messages can be set to trigger on incoming, outgoing or two-way call actions and can be further filtered on IP-based systems by directory number (SIP ID) or ring list values.

Call events include (but are not limited to):

• Call Ringing: When a call is made or received but not yet answered.
• Call Accepted: After the call has been answered.
• Call Ended: After a call has been terminated.
• Group Accepted: When a group call connection has been established.
• Call Queued: To notify a user that their call is in a wait queue.
• On Hold: To notify a user that the current call has been placed on hold.
• Transferred: To notify the user that a call is being transferred to another station.
• Call Setup Failed: To inform the user that the system is offline, and a call cannot be placed

Each message can be set to play only once, or to repeat until the defined call event ends or to play once, followed by a standard ringing tone on some models.

Improving Accessibility for Door Intercoms 

Pre-recorded audio messages are especially useful for door intercom systems, as they can provide guidance to visitors (especially those with disabilities) to confirm that their call has been received and to keep them informed of its status.

Example Use Cases 

1. Visitor rings the call button. Operator’s intercom rings, and a local message is played stating “Your call is ringing, please wait.”
2. Operator answers, and opens the door (by pressing a DTMF tone such as “6”, or a programmed button) and a message is played stating “The door is now open, please enter the building. Have a nice day.” 
3. Door closes automatically and a final message is played to inform the user “The door is now closed. Please use the call button to talk with the operator.”

In cases where the operator has to place the user on hold or if the call is queued, An IP-based system can automatically play a repeating message such as “Your call is on hold, please wait” or “The operator is currently busy. Your call will be answered as soon as possible.”

Automated Messaging for Call Handling 

While a call is actively being made from a master station, local automated messaging is useful to ensure a user knows what’s going on if the operator isn’t available or has to take a call.

Examples: 

• Queued Calls: “Your call is registered but the operator is currently busy. Please wait.” 
• On Hold: “Your call is put on hold, please wait.”
• Call Transfer: “Your call is being transferred, please wait.” 

Automated voice prompts for events such as these prevent users from getting lost or confused when communicating in high-traffic call centers.

Elevator Emergency Communication 

In elevator systems, pre-recorded messaging can play a life-saving role. When the emergency call button is pressed, the intercom will automatically play pre-recorded local and remote audio messages to immediately notify all necessary responders as well as the passengers inside.

Example Use Cases 

Single-Stage IP System Dialing 

While the user is pressing the emergency button, the intercom automatically places a call. The officer’s intercom rings while a recorded message such as “Elevator 101A emergency call” is played through the user’s microphone.

Two-Stage IP System Dialing 

A message is played through both the speaker and microphone such as “Elevator 101A emergency call is registered, please wait”. The intercom then dials the officer. The officer will hear the exact same message in his ear and will know exactly where the emergency call has been placed.

This system is very useful for large buildings with a lot of elevators and areas where it’s not easy to tell which elevator the emergency call is coming from, or if the passenger can no longer communicate with the operator.

Pre-Recorded IP-PA Announcements 

Intercoms can also be configured with PA integration. Operators can trigger a pre-recorded PA announcement by pressing a programmed key on a phone.

Example: 

When a group call is made, all of the receiving stations are first played a “ding dong” tone, then the programmed recorded announcement is played. If a user answers during playback (by pressing a programmed key or dialing an announcement answer code such as 99), the message stops, and two-way communication with the operator can immediately begin.

Benefits of Pre-Recorded Messaging 

• Enhanced user guidance: Clear instructions and reassurance to visitors or callers
• Improved accessibility: For those with hearing, speech or cognitive impairments
• Operational efficiency: Saves time, reduces repetitive operator workload
• Faster emergency response: Improves safety by informing responders quickly
• Professional experience: Shows organized, efficient operation to visitors and staff

Conclusion 

Intercoms with pre-recorded audio messaging capabilities become far more than simple communication devices. They are transformed into intelligent communication and monitoring systems, providing a powerful combination of automation, improved accessibility and reliability. Visitor entry management, queued call handling and elevator emergencies are just a few of the many situations where these systems can provide clear, consistent communication and significantly improve both safety and user experience.

Businesses and facilities looking to upgrade their communication systems and provide an improved user experience should consider intercom systems with programmable pre-recorded audio messaging as a practical and useful enhancement.
