Businesses traditionally used to operate with an in-house PBX that served all of their phone and voice needs. Over the past decade, however, there has been a definite transition away from hardware-based PBXs (private branch exchanges) to software-based services and cloud-based or cloud-hosted systems.
That trend has been accelerated of late. The pandemic caused many still on in-house PBXs to move to voice over IP (VoIP) as a way to keep employees connected, able to access their extensions, and retrieve their voicemails. The idea is to be able to access voice communications from a central web console no matter the location or device.
Today, most systems go beyond basic voice features to also offer video conferencing, team collaboration, and sometimes a lot more. These features are often structured with subscription-based pricing that is cheaper than an old on-premises PBX.
VoIP has suffered from plenty of quality issues over its history, but the level of quality is generally good enough for most business uses. The number of complaints about dropped calls or other issues are generally on a par with cellular networks.
Decision Time for VoIP in the Enterprise
During the pandemic, some organizations adopted a temporary VoIP solution. With many now returning to work, these organizations face the decision of whether to return to an on-premises PBX, shift the status of any temporary VoIP arrangements into a more permanent relationship, or find a new VoIP provider.
The good news is that there are plenty of VoIP options out there. Some services are relatively basic. Others have grand monikers such as Unified Communications as a Service (UCaaS) and operate as cloud-based, virtual PBXs with a whole lot of advanced functionality. In some cases, this might include CRM integration, global call capabilities, and integration with a Public Switched Telephone Network (PSTN) gateway or other legacy phone system functions.
Key Features of Business VoIP Solutions
There can be a tremendous variety of features offered among the VoIP providers. This largely depends on their roots. Those who began in physical PBXs or software PBXs provide different capabilities compared to those who grew up in the cloud. Similarly, some gravitate to the SMB segment, others cater more to large enterprises, and quite a few attempt to serve all needs.
Thus, the feature set, pricing, and breadth of offerings can be wildly different. That said, most vendors should provide the bulk of the following features:
- Centralized device management to easily manage all voice and related features without the need for complex administrative tasks.
- Unified communications and mobile app integration so all employees can easily collaborate from their preferred device.
- Call routing.
- Call recording.
- Call queuing
- Caller ID
- Additional features such as call transfer, call hold, 3-way calling, music on hold, paging, intercom, Spam call blocking/tagging, 911 admin notification, voicemail-to-email transcription, depending on needs. Some providers bundle all of these for one price, others have tiers of service that provide more of such functions if required.
- Phone system reliability without outages, downtime, or low call quality.
