IP communication provides for device mobility. For example, a residential broadband connection may be used as a link to a virtual private network of a corporate entity, in which case the IP address being used for customer communications may belong to the enterprise, not being the IP address of the residential ISP. Such off-premises extensions may appear as part of an upstream IP PBX. On mobile devices, e.g., a 3G handset or USB wireless broadband adapter, the IP address has no relationship with any physical location known to the telephony service provider, since a mobile user could be anywhere in a region with network coverage, even roaming via another cellular company.

Figure out how much you’re willing to spend on your VoIP and this will help you better hone in on the company that’s right for you. Your residential VoIP should cost less than your current landline, but it’s still smart to do some price comparison and see which companies offer special deals (for instance, many companies will offer you a better rate if you sign up for a year plan rather than a month-to-month plan). Take a look at your monthly phone bill and the features you’re paying for, and compare that side-by-side with what you’d be signing up for with a VoIP plan.

However, VoIP traffic to and from the on-premises systems can often also be sent over secure private links. Examples include personal VPN, site-to-site VPN, private networks such as MPLS and SD-WAN, or via private SBCs (Session Border Controllers). While exceptions and private peering options do exist, it is generally uncommon for those private connectivity methods to be provided by Hosted or Cloud VoIP providers.
If you're wondering what you get with a softphone that you won't with a standard phone handset, then that depends on the service. Business-class softphones offer all kinds of features related to online meeting collaboration, call routing, multi-line conference calling, and more. From a residential VoIP perspective, you'll most often find video conferencing (though more and more this is becoming a separate product from most providers), a voicemail-to-text converter, detailed call records, and user controls for users other than yourself. Some services also offer faxing, text chat, and call metering so you can see how much you're spending.

First, there might be a very low cost or even free "basic" or "introductory" tier that's just so feature poor that the vast majority of customers will opt for the next level up, which will be the full-priced tier. Another common practice is a one- or two-year contract, each with a slightly lower price that are offered next to a significantly higher-priced month-to-month tier. Additionally, while most residential VoIP services offer unlimited calling, some vary their pricing on call restrictions. Those will come either in the form of minutes (with higher pricing attached to monthly overages) or geographic region. The latter usually start with nationwide calling and then tack on another charge for worldwide calling or even separate charges for different countries.

Operators of "Interconnected" VoIP (fully connected to the PSTN) are mandated to provide Enhanced 911 service without special request, provide for customer location updates, clearly disclose any limitations on their E-911 functionality to their consumers, obtain affirmative acknowledgements of these disclosures from all consumers,[65] and 'may not allow their customers to “opt-out” of 911 service.'[66] VoIP operators also receive the benefit of certain US telecommunications regulations, including an entitlement to interconnection and exchange of traffic with incumbent local exchange carriers via wholesale carriers. Providers of "nomadic" VoIP service—those who are unable to determine the location of their users—are exempt from state telecommunications regulation.[67]

A VoIP media gateway controller (aka Class 5 Softswitch) works in cooperation with a media gateway (aka IP Business Gateway) and connects the digital media stream, so as to complete the path for voice and data. Gateways include interfaces for connecting to standard PSTN networks. Ethernet interfaces are also included in the modern systems which are specially designed to link calls that are passed via VoIP.[26]
It gets even better! Calling internationally using VoIP is far less expensive than using a traditional landline phone company. Every region of the world, from Afghanistan to Zimbabwe, has its own combination of technological development, geographic obstacles, regulations, and taxes. Cell phone carriers, much like VoIP providers, have their own network, which is why it usually costs more to call international cell phones. If a VoIP provider has a significant presence in a country, it’s likely that landline calls will be unlimited with an international package. For example, if you are using Vonage Word, calling from the U.S. to a landline in Germany is included, but it costs US$.0061 per minute to call a cellular phone. If you are using ViaTalk World, you can call both German cell phones and German Landlines for the same rate – free up to 1200 minutes per month. Don’t forget that with every VoIP provider, if you call within their own network, calls are always free no matter where you are in the world. With the development of SIP, you can easily make and receive free international calls from your home using VoIP.
