How many sides have a voice mail communication

In a traditional voice mail communication, there are typically 3 sides:

1. The caller: The person who initiates the call and leaves a message.
2. The recipient: The person who receives the call and has a voice mail box where the caller's message is left.
3. The voice mail system: The automated system that records and stores the caller's message, allowing the recipient to retrieve and play it back.

However, in modern voice mail systems, there may be additional "sides" or parties involved, such as:

4. The network: The telecommunications network that carries the voice call and voice mail messages.
5. The service provider: The company that operates the voice mail system and provides the service to the caller and recipient.
6. The administrator: The person or team responsible for managing the voice mail system, setting up accounts, and troubleshooting issues.

So, depending on the specific context and technology used, there may be 3, 4, 5, or even 6 "sides" involved in a voice mail communication.
