Corporate Phones category includes all telecommunications products and services a company uses. Some companies have moved entirely away from landlines or are now using VOIP in the office. VOIP option may save a company a significant amount of money especially if their employees make international calls on a regular basis. In addition, it allows for multiple connections on the same line enabling conference calls that a traditional phone line does not support. Smaller companies may choose to work entirely by cell phones without any office phones. Reviews for corporate phone suppliers can be found on VendOp.
