Vertex’s IP-PBX business phone systems are designed to meet the voice and data convergence requirements necessary to run your business. With its superior voice quality, Vertex IP-PBXs can help your employees connect regardless of where they are physically located. Using Vertex's Voice-over-IP (VoIP) solutions can keep your employees connected with your customers and each other. Below are some frequently asked questions about IP-PBX, Voice-over-IP, VoIP, and IP telephony?

What is an IP-PBX?

An IP-PBX is a customer premises business phone system that manages telephones throughout the enterprise and acts as a gateway to both voice and data networks. An IP-PBX allows you to place calls using a network instead of standard telephone infrastructure. Telephones can be connected to the IP-PBX via the network and calls can be routed via the network instead of the standard public switched telephone network.

What is IP telephony?

IP Telephony or Internet Protocol Telephony is the transmission of voice signals over the Internet, wide area network (WAN), or local area network (LAN). IP Telephony uses voice-over-IP to break down voice transmissions into packets of data and transmitting them across a network.

What is Voice-over-IP?

Voice-over-Internet-Protocol or Voice-over-IP or VoIP allows one to send a voice transmission via a network instead of the standard telephone infrastructure. Calls can be routed via the Internet, wide area network (WAN), or local area network (LAN). 

What are the advantages of an IP-PBX system?

Multiple Branch Offices

With VoIP, expanding your business phone system to multiple branch office sites is easy. Integrated IP Gateways allow you to traffic calls between offices over the Internet and save on long distance charges. Dialing branch offices is as easy as calling an extension down the hall. Make certain that your IP-PBX has an administration tool that simplifies the process of configuring IP gateways between remote systems.

Toll Bypass
IP-PBXs enable businesses to reduce the cost of long distance calling by routing calls inexpensively over IP networks. If you have overseas facilities, using an IP-PBX could reduce your business's costs significantly.

Remote Office

Even if your business has a single remote office, an IP-PBX can give you the flexibility to pick an affordable solution. Purchasing a solution that allows for a small or large number of IP trunks might be right for you.

Work From Home

How do IP-PBXs work with other applications, including legacy applications?

The Vertex platform can host both custom and third-party applications, managed locally or remotely. Vertex also provides a simple, script-based development environment for custom applications to address specific customer needs. The Vertex solution can also be tightly integrated into backend applications and databases enabling companies the ability to provide new customer-facing applications like inventory look-up. Other vendors require additional servers (dedicated for some applications), again adding to the cost of the solution

What makes an IP-PBX an applications platform?

The platform should be fully application-ready, with the processing power and memory to support third-party applications. The system should be standards-based and use standard application programming interfaces like VoiceXML and TAPI.

Can I use an IP-PBX system if I want to keep my existing analog and digital handsets?

Support of legacy and analog and digital handsets should be a top requirement for most IP-PBX installations. Why throw away your existing phones and wiring, when the right IP-PBX solution can work with legacy handsets as well as IP?
