1-VoIP is a service designed to be simple and affordable without some of the bells and whistles that other providers offer. For some, this should be a welcome offering. For others who want a more advanced, feature-rich offering, 1-VOIP may fall short of expectations. The service starts at under $10 per month and provides all basic phone services including voicemail, caller ID, call waiting, and more. However, there is no mobile app or desktop interface to take your calling on the go. Essentially, your business can save on phone costs and give up the mobility features offered by competitors. Plus, the setup is amongst the easiest of all the providers on this list. For simplicity and low cost, 1-VOIP checks off all the boxes.
As mentioned above, alerting callers that they won’t be getting an immediate call back is of upmost importance for an entity’s reputation and a caller’s satisfaction.

Cell phone voicemail greetings are generally more personal and casual than office phones. Consider a greeting like “Hello, you’ve reached [your name]’s cell phone. I can’t take your call at the moment, but if you leave a brief message, I’ll get back to you as quickly as possible.”
Freshdesk's features match the ones offered by the other best virtual phone number providers on our list. However, it is the only provider of robust call center features like a multi-level interactive voice response system that routes your customer calls to teams or agents with a customizable call-flow mechanism. You can configure the system any way you wish – callers could press 1 for Customer Support, 2 for Sales and 3 for another department unique to your company.
