Whether you’re out for the day or are off for the week, the first rule of an out of office voicemail greeting is: let callers know when you’ll be back! You’ll save them the frustration of continuing to call and yourself the hassle of listening to redundant voicemails. It’s also a good idea to set the expectation of whether you are answering messages while you’re away, and who they can reach for assistance in your absence.

VoIP systems, sometimes called cloud PBXes, can manage all your voice communications from a central web console no matter how many extensions you've got, where your employees are located, or even what devices they're using. Most systems also offer features like video conferencing and team collaboration. Put all that together with subscription-based pricing that's generally much cheaper than an old-fashioned, on-premises PBX, and VoIP remains one of the best communications investments any business can make, especially during the pandemic.
