Double phone tapping: challenges and solutions for companies
Double phone tapping is a must for call centers and high-performance customer services. This method, which enables a supervisor to discreetly listen in on an ongoing conversation between an agent and a customer, offers numerous advantages for improving service quality and effectively training teams.
Whether you’re using a traditional fixed telephony system or a modern VoIP solution, double-tapping can be set up easily and legally, provided certain ethical and legal rules are respected. Applications like Kavkom integrate this functionality directly into their interface, enabling real-time monitoring, call recording and even automated conversation analysis.










Understanding double-tapping

Definition and basic principles
Double phone tapping is a technique that allows a third party to listen in on an ongoing telephone conversation. It applies to both landline and cell phones. Here are the essential points to remember:
- How it works: A supervisor can connect to a call in progress without the callers being aware of it.
- Applications: Mainly in call centers and customer services for training and quality control.
- Technologies : Modern software solutions like those offered by Kavkom facilitate this practice on GSM and VoIP networks.
Double eavesdropping differs from conventional phone tapping in that it is carried out in real time and generally for professional purposes. It should not be confused with illegal surveillance systems or spyware such as Pegasus, which aim to eavesdrop remotely without authorization.

Legal and ethical framework
The use of double-tapping raises important questions about privacy and professional ethics. Here’s what you need to know:
- Legal framework in France: Double eavesdropping is authorized in a professional context, but must comply with certain conditions.
- Consent: Employees and customers must be informed of the possibility of double-tapping.
- Data protection : Recordings must be secure and used only for the purpose intended.
- Limitations: Eavesdropping on surrounding conversations or using surveillance applications without consent is illegal.
To stay within the law, it’s crucial to establish clear and transparent policies regarding the use of double-tapping in your company.
