Google Voice
Google Voice is the finest choice if you're seeking for a free virtual business phone software. You can combine G Suite with all of your existing Google Apps for business if you already use G Suite.
Video Conferencing
The app may be used to control all business communication features, including caller id, caller routing, call recording, waiting, ringtones, vacation answers, and business hours. The icing on the cake includes voicemail, text messaging, video conferencing, call to email transcription, and more affordable local and international calls.
Instead of merely using a physical phone line, you can use it on your own cell phone with mobile apps, your laptop computer, current desk phone, and other devices.
Multiple employees may simultaneously use the same number. Additionally, you can give each member of the team their own phone number or an extension.
