VoIP Software

8 tools available

VoIP Software moves business phone calls to the internet. A new employee gets a working extension in minutes — just download an app. No wiring, no desk phone, no IT request. International calls cost almost nothing.

Voicemail transcription, call forwarding, and video meetings come built in. The entire phone system travels with each person, whether they're at a desk or working from the couch.

For remote teams and growing companies, VoIP is usually the single biggest telecom cost cut they'll ever make. Once the switch happens, the old copper phone line starts to feel like a fax machine — which is to say, ancient.
