Gone are the days when business phone lines ran on physical phone lines. With the introduction of the Internet, there's simply no need to be using such age-old technology.

SIP trunking has taken the world by storm ever since its introduction. This software methodology allows companies to connect incoming calls from customers and prospects to their employees without using physical phone lines anywhere in the process.

If you're in the market and checking out the different SIP trunking providers that can help your business's sales and customer service departments get up and running, then you're in the right place. In this article, we'll go over five of the best SIP trunk providers to help you decide which one to go with.

1. Bandwidth

The principal benefit that Bandwidth provides as a SIP trunk service provider is there ability to combine calls from both local and long-distance circuits into one neat package. 

The end result is that there is less for you to set up as a customer to get your departments up and running with Bandwidth technology. The cost of the service is $0.015/minute, which is significant if you use many minutes but could work in your favor if you do not. Most other providers charge flat monthly rates.

2. Megapath

With Megapath, you can start taking advantage of voice over IP using the existing IP PBX system that you already have in place. Like Bandwidth, this translates to less work on you to get things set up.

Unlike Bandwidth, the pricing strategy for Megapath is on a per-month basis. However, the cost of the program is pretty cheap, clocking in at only $9.95/month. What's more, the company offers a 30-day money-back guarantee if the first month of service doesn't satisfy you.

3. Twilio

Twilio is probably one of the most famous VoIP providers out there, period. Their SIP trunking service line is just as good as you would expect.

Their service is design elastically, meaning that it will scale with you as your business grows and you experience higher call volumes. Pricing starts at $0.0045/minute ($0.0018/minute if you want a toll-free number). The cost-benefit analysis here lines up very much in your favor if you don't use a toll-free number.

4. Verizon

Many folks think that Verizon is a consumer-oriented company, but Verizon also has a B2B SIP trunking service. Like Megapath, Verizon's service will integrate with your current IP PBX system.

Because of the size of customers that Verizon typically works with, they do custom quotes and don't release pricing publicly. You'll have to call in to get a quote and complete the cost-benefit analysis for your company.

5. CloudPhone

CloudPhone's biggest claim to fame is the inclusion of a virtual receptionist that can route calls appropriately with every phone plan. The most basic plan should suffice for most small businesses and costs only $24.95/month. If the virtual receptionist is important for you, then CloudPhone is a no-brainer to provide a return on your investment into its SIP trunking service.
