The voice mail system is a favorite venue through which hackers break into your phone system and ring up enormous phone bills. Encourage voice mail courtesy. Voice mail should be used as a tool to help people communicate, not a screen to avoid phone calls. The major advantage of PC-based systems are lower prices. Because these systems use standardized PC components, they benefit from the production efficiencies of mass-produced computers.
Proprietary systems are still a force at the extremes of the market.
For very small companies, simple proprietary voice mail systems do not need all the complex hardware of a standard PC, and thus can be less expensive than even small PC-based systems. However, these systems are usually limited in terms of expansion capabilities and functionality. On the high end, most voice mail systems for large companies are still based on proprietary hardware designs. These systems are better able to handle the load when hundreds of users will frequently access the system. When choosing a system, you should focus on finding a system that will work well with your phone system.
