For social media marketing agencies, VoIP business phone services offer an integral basis for multichannel communication – both within teams and with clients. 

Today’s business phone service providers no longer limit themselves to voice calls. And the days of cumbersome office PBX systems are long past. 

Instead, providers use Voice over Internet Protocol (VoIP) to route communication through the cloud. Most of them offer a comprehensive set of channels – from voice and video calling over conferencing to integrated messaging, email, and live chat. 

All these services are available on softphone apps for internet-enabled devices from smartphones to tablets – ideal for remote teams. Most providers also support regular office desk phones.  

In addition, these business phone services provide productivity features like advanced call routing, AI analytics, and integrations with other business apps. 

In 2020 and beyond, this can be a saving grace for social media marketing agencies. 

Between teams forced to work remotely during the pandemic, and clients demanding customer service via a multitude of channels, VoIP business phone services can help you centralize communication and increase efficiency. 

Here are the 5 best VoIP business phone services in 2021.
