The potential of VoIP exceeds some of the abilities of traditional communications systems. After years of using traditional business communications systems, we have all taken the high quality and reliability for granted. To replace a traditional PBX/Key System with a VoIP application and expect the identical quality and reliability is certainly possible, but sometimes very expensive. When designing a business communications application with VoIP, there are several levels for an enterprise to consider during this process. From installing a completely brand new system to upgrading your existing telecom system, your application needs to be designed with your requirements in mind.
Most manufacturers provide a broad array of VoIP choices with their products. The most popular applications in a business environment are networking multi site locations and allowing remote users to log into the system from anywhere that has a broadband connection. For instance, a business with three locations can run each location with traditional PBX/Key System technology, but combine VoIP technology to network all of the systems via data connections. The benefit is that all employees are reachable with an extension number and share the same messaging and communication resources.
The remote user can be part of the same system no matter where they are and receive the same benefits. The company can be reached at a single telephone number and calls can be distributed to the various branch locations over VoIP by automated attendant, live operator or DID.
When a remote teleworker makes a call from a soft phone or other device, the call is either connected peer to peer to another VoIP user or connected to another user over the PSTN.
