How Can Organizations with Legacy Systems Benefit from VoIP?

June 13, 2017




While startup companies may have the luxury of choosing a voice over IP (VoIP) telephony solution from the beginning, millions of companies aren’t so fortunate. This doesn’t mean, however, that organizations with legacy telephone systems can’t benefit from voice over IP.


A VoIP gateway allows companies with traditional telephony to bridge the gap between their private branch exchange (PBX (News - Alert)) and a modern VoIP connection using SIP technology. The VoIP gateway is put in place and tasked with the compression and decompression of voice and fax traffic, packetization, call routing, and call signaling. It converts all calls into (and out of) digital packets between the traditional PSTN and an IP network in real time. The gateway is installed in conjunction with an integrated access device (IAD), a device located in your office and in between your router and PBX. With the IAD, you can keep your existing PBX and phone configurations and take advantage of all that VoIP calling has to offer a business.

There are a number of reasons a company would want to consider a VoIP gateway:

To save money. With VoIP, companies can save dramatically on long-distance calls, particularly international calls. (In some cases, international calls can be made at half the cost of traditional landline-based communications). Since there’s no hardware involved, you’ll eliminate the need to update and maintain equipment.

Expand your voice services. If your current system doesn’t allow functions such as call forwarding and parking, voice conferencing and “follow me” services, you can add them to your telecom infrastructure quickly and easily with a VoIP business solution based on gateways.

Improve reliability. If your phone system hardware were to fail, what would you do? How would you handle the downtime? By deploying VoIP in the cloud and eliminating hardware, you also eliminate the headaches of potential failures that can lead to lost revenue.

No worrying about upgrades. With premise-based equipment, upgrades are a constant worry and a source of lost time for the IT department. A business VoIP solution puts upgrades and maintenance into the hands of your service provider, not your organization.

Mobility. Because a business VoIP solution represents an account, not a physical location like with legacy telephony, it can travel with you and employees, even over mobile devices. All you need is an IP connection and your VoIP system will recognize any phone as a handset and allow you to make calls.

If you’re interested in gaining the benefits of a voice over IP system but wish to preserve your investment in your legacy system, a VoIP gateway is a reliable and affordable way to bridge the gap.
