Historically, companies had no choice but to purchase a proprietary phone system, where all the components-switch (PBX), handsets, peripherals, and applications-came from a single vendor. These systems were expensive, poorly supported, lacked scalability, and slowed or interrupted business growth. 

Vendors continue to sell proprietary systems today because they are lucrative and lock a customer into a single source of hardware for the long term. 

Driven by customer requirements for additional flexibility and affordability, the phone industry is now undergoing a similar shift towards open systems as the computer industry experienced. As a result, customers are enjoying significantly better products at a greatly reduced cost.
