Frequently asked questions

  • A network of phone extensions connected to one phone line. It’s more efficient and less expensive than installing separate landlines for each employee.

  • Install one phone line and set up as many extensions as you need. Call within your organization or externally and use features like voicemail, on-hold music, automated menus, and conference calls.

  • Choose between traditional Public Switched Telephone Network (PSTN) systems, which use a landline, or Voice over Internet Protocol (VoIP) phone systems, which use your internet connection. Go with VoIP for more features and device flexibility.
