The products and services in this review roundup are focused on business use and because of this either provide some PBX features or serve as full-on virtual PBXes. This may mean, among other things, that they provide service to telephone sets on your employees' desks. Most also support electronic faxing in some fashion, either directly (which can be a significant challenge for some VoIP services) or by simply integrating an incoming fax with your email system. Other popular features are video conferencing and shared meeting software (so meeting attendees not only hear each other but can present presentations or documents in a shared work space).
In India, it is legal to use VoIP, but it is illegal to have VoIP gateways inside India. This effectively means that people who have PCs can use them to make a VoIP call to any number, but if the remote side is a normal phone, the gateway that converts the VoIP call to a POTS call is not permitted by law to be inside India. Foreign based VoIP server services are illegal to use in India.
Though many consumer VoIP solutions do not support encryption of the signaling path or the media, securing a VoIP phone is conceptually easier to implement than on traditional telephone circuits. A result of the lack of encryption is that it is relatively easy to eavesdrop on VoIP calls when access to the data network is possible. Free open-source solutions, such as Wireshark, facilitate capturing VoIP conversations.

Few things in life are set in stone, and the same should be true of your VoIP plan. It’s wise to find a plan that is scalable and which you can easily expand if need be. You’ll want to know if you can break your contract early if you find a better deal elsewhere, or if you can easily switch plans with the same company in order to take advantage of more features, or to get rid of some you don’t need.
SIP networks usually have a proxy server and a SIP gateway. The proxy sever helps lighten the functional requirements of SIP endpoints. It also acts as both client and server, but it adds functionality around call routing and policy-based management. SIP gateways handle the routing and connectivity requirements for connecting SIP calls to other networks. Typically, the advanced features of the VoIP vendors we review here are largely based on the proprietary management technology they build into their proxy servers and gateways. By offering VoIP solutions where these elements of a SIP solution are hosted in the cloud, the providers reviewed here have more flexibility in building advanced features since they have more control over deployment and reliability.
Vonage is probably one of the most well-known PBX providers on the market—and for good reason.

Vonage also offers integrations with everything from Salesforce to Slack. So if your business outgrows your current customer relationship management tools, you can switch without having to worry about whether your VoIP communications service offers integration with your new CRM.
As a consultancy marketing business for small-business owners, part of our business is to help small-business owners set up their VoIP and local phone numbers. We used to have RingCentral, and we advised our clients to use it. RingCentral gives you a local phone number regardless of whether you are in the building or not—or even in the city. You will always have a local phone number that you can redirect to any cell phone, depending on who’s working in the company. RingCentral offers good customer service and has great flexibility, but it’s a bit expensive.
The following table provides a high level summary of how residential VoIP service compares to other alternative solutions for home phone service. The table compares this service to a regular landline, a bundled phone service from a cable company such as double or triple play, and a cell phone service. The cell phone is included as some people decide to just get rid of their wired phone and use their cell phone for all calls. Free services such as Skype are not included as they are not effective, like for like, landline replacements in our opinion.
