How an E-Mail Becomes a Phone Call

Published on June 26, 2024

Fault messages are often issued by the triggers themselves in email format. This method is used when the physical transmission of data via contacts and cables is not possible or too expensive, e.g. due to long distances. But can the responsible recipient also be reached via e-mail, e.g. due to being on call? And is the signaling of an incoming e-mail even sufficient to attract as much attention as a ringtone for a phone call could? DAKS offers various options for converting an e-mail into a call and even for starting complex broadcast call processes. 

Convert e-mails to calls with the DAKS 'Mail-to-Phone' module

Example

The filling plant sends an email

In a filling plant, the volume has fallen below a certain level. The system automatically sends an email with the exact fault data to the Mail-to-Phone server.

DAKS calls the responsible service technicians

DAKS calls – via a single call or group call – the responsible service technician or technicians. A special ringing tone can be set in the Mail-to-Phone server so that the called parties can immediately recognize that this is a fault message and not a normal call.

The service technician hears an announcement

A service technician takes the call and hears an announcement:"You have received a message" and "With the star or pound key, you can browse forward or backward within the message".

The text appears on the display

Now the recipient can read the complete message on the display of any text-capable terminal device. 
For mobile devices, the email text can also be output as SMS if desired.

The user can accept the order at the touch of a button

If a confirmation is requested, an additional announcement is played: "Please confirm the message positively with 1 or negatively with 0." The feedback about accepted or unaccepted calls as well as positive or negative confirmations is sent directly back to the initiator of the email.

This makes the DAKS 'Mail-to-Phone' module a further building block for optimum mobile accessibility and reliable alerting.

Convert emails to calls with DAKS-IoT

Customers who already have an IoT environment with Node-RED in use can also implement the conversion very easily with the DAKS IoT nodes:

Example

Node-RED is connected to the e-mail system

Node-RED logs on as a user to an inbox (this can be an internal e-mail server or an external hosted service).

A device sends an e-mail

If, for example, the refrigerator temperature exceeds or falls below a defined temperature range, an e-mail is sent.

DAKS-IoT recognizes an alarm e-mail

Node-RED first evaluates whether the subject field of the e-mail contains the word "Alarm". Only then are the emails processed further.

DAKS-IoT processes the e-mail content

The content of the email is then split up and the body is filtered. 

Only the relevant part of the body is copied into the message and transferred to the ESPA-X interface.

DAKS calls the responsible service technicians

DAKS calls the responsible technical team. The message is displayed on a text-enabled device and can also be played as an announcement via text-to-voice. 

They can accept the task at the touch of a button

If an acknowledgement is requested, an additional announcement is played: "Confirm the message positively with 1 or negatively with 0." The feedback about accepted or not accepted as well as positive or negative acknowledgements is sent directly back to the initiator of the e-mail.

DAKS-IoT also controls third-party systems

DAKS-IoT can also use the information from the email to control third-party systems. For example, DAKS-IoT can report system statuses to the dashboard of the building management system via ModbusTCP. 

 

Use these three functions for an even smoother alerting process

Alarm tone for more attention
Very important messages also need very special attention! If the email is marked with "Importance high", the broadcast call started by DAKS can ring on all appropriate end devices in a conspicuous alarm tone. This makes it immediately clear to the recipient that they must deal with this message without delay.

Read aloud with 'Text-to-Voice'
With the additional DAKS module 'Text-to-Voice', participants can even have the email text read aloud to them.

Skipping unnecessary text passages in long email texts
Some systems issue emails with very long texts, containing texts / data that are not necessary for a quick response to the error and are more likely to annoy when receiving the message. Use the 'Parse' function, to set trigger words in the broadcast call, so that texts will only be transmitted from certain passages.

 

By the way: It also works the other way round

Do you want to do exactly the opposite, namely send your broadcast call as an e-mail? The DAKS portfolio is also equipped for this: The DAKS 'E-Mail Dispatch' module ensures that a broadcast call can also be sent as an e-mail and is a further building block for reliable alerting and communication with DAKS. The fact that DAKS can accept and convert messages from a wide variety of (heterogeneous) infrastructures and output them in many different formats and media like no other alarm server is one of the keys to this reliability. After all, important messages should reach their recipients under all circumstances – regardless of where they are or whether they are in such noisy environments, for example, that it is almost impossible to listen to an announcement. 

Conclusion

These and many other circumstances are not the exception in real working life, but the rule, not least because workplaces and workflows are becoming increasingly mobile. DAKS therefore takes care of what you don't need to think about for every situation and always issues every message in both voice and text form. This in turn enables communication via a wide variety of media and channels with the aim of reaching the person responsible for each task within the right time.
