Shared call appearance definition
Shared call appearance is a telephony feature that allows a single telephone number to be assigned across multiple devices. Users can answer incoming calls to the shared number from any associated device.
SCA is a typical feature in VoIP and private branch exchange systems, allowing for flexible call management within organizations.
Risks associated with SCA
- Security. SCA increases the risk of unauthorized access to calls or voicemail. If one of the devices is compromised, it might expose the entire network to security threats.
- Privacy. SCA can lead to privacy breaches, especially if a call is picked up on a shared line in a public or less secure space.
- Dependency on network and systems. Any network issues or system failures can impact all devices with a shared number.
- Overlapping calls. Situations where multiple users use the same line at once can lead to interruptions and confusion.
- Monitoring and Compliance. For businesses that require call monitoring, SCA complicates these processes.
- Training and usage. Ensuring all employees understand how to use SCA appropriately and comply with organizational policies sometimes requires significant training and oversight.
- Potential for misuse. There’s a risk of abuse of the shared line, where employees might use the business line for personal calls or, in a worst-case scenario, for fraudulent activities.
