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.
