Key components of VoIP systems

VoIP for small businesses facilitates efficient communications with customers and among team members thanks to its various capabilities. These are the features included in cloud-based phone systems:

  • Unlimited calling: VoIP solutions offer unlimited domestic calling within the U.S. and Canada, with some extending the coverage to overseas territories, like Mexico. Others offer unlimited international calling, benefiting companies with clients abroad. When you compare VoIP and cellular services, the former offers more significant money savings since it doesn’t come with roaming charges that apply to the latter.
  • Call management: These tools include call forwarding, call transfer, hold music, call waiting, and call queues, which enable teams to handle incoming calls in an orderly manner.
  • Mobility: A softphone app compatible with iOS and Android systems helps users place and accept calls outside the office. Voicemail transcription makes referring to message details easier, especially when traveling. Virtual fax lets you send and receive fax messages wherever you are.
  • Phone numbers: Most VoIP systems offer local phone numbers, while others offer toll-free and vanity numbers. Still, some provide local numbers in overseas locations.
  • Analytics: A customizable analytics dashboard shows various performance metrics in real-time. Some VoIP solutions feature robust historical reporting tools, wherein you can generate custom reports based on the performance areas you want to track and evaluate.

Benefits of using VoIP systems

Businesses will find VoIP platforms valuable in streamlining communications. The advanced call management features — designed to direct customers to the right agents and create a pleasant call experience — contribute to customer loyalty in the long run. Aside from customer communications, VoIP systems improve team collaboration as they offer access to instant messaging and video conferencing.

Similarly, VoIP systems help lower communication costs. You won’t have to spend on installing and maintaining phone lines and hardware equipment, as in landline systems. The money savings are greater in the long run, especially when you add more users to the phone system since there’s no need to install extra physical phone lines.

When you choose a hosted VoIP solution, you only pay a fixed monthly fee per user. The maintenance of the infrastructure is already included in your subscription.

Considering all the ways this service can be leveraged, it’s important to find the right VoIP providers for your small business. After all, not all businesses have the same exact needs.
