It is a phone service that uses your internet connection to make and receive calls. It also offers more communication functionality and options for your business to use. It gives you the flexibility to conduct your work from anywhere, and on any device.
The problem there is that VoIP traffic is much more sensitive to network bumps and potholes than most general office traffic. That translates to garbled conversations, difficulty connecting over Wi-Fi, or (worst case) dropped and lost calls. If your business is small and your network is essentially contained in one or two wireless routers, then your configuration and testing headaches might be fairly easy (though still there). For medium and larger networks, these tasks can be complex and time-consuming, which translates into added cost in terms of man-hours.

Voicemail transcription is a service that converts audio voicemail messages into text format, which is then sent to the user via email or text message. It is sometimes referred to as ‘speech to text’, ‘voice to text’ or ‘voicemail to text’.
Voicemails need to maintain a professional consistency that’s aligned with the entity it’s representing. That said, the structure can vary depending on the situation. There’s no template set in stone. In fact, trite and generic should be off the table. The goal should be a balance of uniqueness and practicality.
