This allows you to keep your personal number private while establishing a dedicated line for business purposes.

What should I consider when setting up a 2nd phone line for my business?

Here are some key factors to consider:

  • Features: Identify the functionalities crucial for your business, such as unlimited calling, texting, call recording, or voicemail transcription.
