| Considerations | Analog | VoIP |
| Line Setup | High. Landline setup usually charged at $50-100/line. | Low. VoIP trunk can be installed in minutes with little or no setup fee. |
| Maintenance Cost | High. Maintenance has to be done by a technician onsite, which is expensive. | Low. With a hosted VoIP solution, your provider will responsible for all the maintenance and update. |
| Call Pricing | Higher monthly service fees and calling rates. | International and mobile calls typically charged at a much lower rate. Potential 60% lower phone bills. |
| Add-ons | Limited options for add-ons. Most advanced features cost extra or require additional hardware. | Rich advanced features available at no additional cost (auto attendant, softphone application, etc.) |
