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.
When you create a voicemail message, the next thing you need to ensure is that your prospects are aware that they have reached the right person so no confusion takes place.

No one wants to listen to a two-minute voicemail greeting. Keep it short and upbeat and start with a simple “Hello! Thank you for calling !”. If you make your voicemail greeting too long, customers will feel like you are wasting their time.
As far as pricing goes, costs will vary from provider to provider. Some basic VOIP plans only require users to pay government-mandated 911 fees, which helps keep costs low. Of course, as with most things in life, you get what you pay for. Basic VOIP plans may not include many of the advanced features that you’re looking for. The good news is that most VOIP providers offer clear, transparent pricing on their website with each tier displaying the features it holds. This makes shopping and comparing very easy.
