The T.38 protocol is designed to compensate for the differences between traditional packet-less communications over analog lines and packet-based transmissions which are the basis for IP communications. The fax machine may be a standard device connected to an analog telephone adapter (ATA), or it may be a software application or dedicated network device operating via an Ethernet interface.[35] Originally, T.38 was designed to use UDP or TCP transmission methods across an IP network. UDP provides near real-time characteristics due to the "no recovery rule" when a UDP packet is lost or an error occurs during transmission.[36]

Overall, VoIP is simply the better option for the vast majority of customers. Dropping your landline means no more hidden fees or metered long distance calling charges. Everything is charged at one low rate by most providers and your ability to customize your phone service to exactly what you need is far greater. Unless you've got some highly unique circumstances that somehow mandate a landline, VoIP is simply the better choice.
A business phone system helps you to present a professional image to your customers. If you do not have a need for office phones or spend the money, you can still use a virtual phone system to project a professional look. This enables you to place a call directly to a mobile phone.

Voicemail routing can take multiple forms, but they're basically rules you can apply to incoming calls that will automatically route them to voicemail without even causing a ring. For example, if calls come in with Caller ID blocked, those can be routed directly to voicemail. Or if you're simply not into talking to anyone, you can hang out a digital Do Not Disturb sign and route all calls to voicemail, perhaps until you're feeling more social or every day between the hours of 9 PM and 7 AM. 

While home VoIP systems are fairly straightforward to set up and use, a VoIP system for all but the smallest of businesses can be quite complex, In addition to have multiple users, business VoIP systems have complex feature sets that are necessary to conduct business in today's world. In addition, a business VoIP implementation must take into account the existence of the data network, even though in most cases it won't share the same infrastructure. This will mean switches and routers optimized for voice traffic, and security that's suitable for both business and VoIP.


There are some solutions to this issue if you have concerns. The most obvious is to utilize Uninterruptable Power Supplies (UPS) for those short outages, or a generator if you live somewhere where outages are more common (and for your fridge!). With so many people having cell phones these days most people will not be too concerned with this issue, especially when they consider the money they are saving. Most services include a call forwarding feature so you can always set that up to go to your cell phone so you do not miss important calls.
Mobile clients are softphones optimized for a particular mobile OS and for being used in mobile situations. This means they're designed to switch easily between different cell and wireless connections on the fly. This means you can let your employees use whatever the cheapest wireless connection around them happens to be—and often that can be free. They also let your employees use your company's phone system on their own devices.

Make the switch, and leave those switchboards in the dust…you won’t regret it – Get VoIP!
For a VoIP system to work, it needs a means of routing calls between users or to the outside world. In a cloud based system, a virtual PBX does that job. What that means to you is that the provider is running a large PBX operation in a data center somewhere, and slicing off a little of it to dedicate to your organization in exchange for your money. You're essentially sharing a large PBX with that provider's other customers, but because these companies use multi-tenant segmentation, your PBX will appear dedicated to you. This engine will take care of routing calls on your VoIP network.

In the following time span of about two decades, various forms of packet telephony were developed and industry interest groups formed to support the new technologies. Following the termination of the ARPANET project, and expansion of the Internet for commercial traffic, IP telephony was tested and deemed infeasible for commercial use until the introduction of VocalChat in the early 1990s and then in Feb 1995 the official release of Internet Phone (or iPhone for short) commercial software by VocalTec , based on the Audio Transceiver patent by Lior Haramaty and Alon Cohen, and followed by other VoIP infrastructure components such as telephony gateways and switching servers. Soon after it became an established area of interest in commercial labs of the major IT concerns. By the late 1990s, the first softswitches became available, and new protocols, such as H.323, MGCP and the Session Initiation Protocol (SIP) gained widespread attention. In the early 2000s, the proliferation of high-bandwidth always-on Internet connections to residential dwellings and businesses, spawned an industry of Internet telephony service providers (ITSPs). The development of open-source telephony software, such as Asterisk PBX, fueled widespread interest and entrepreneurship in voice-over-IP services, applying new Internet technology paradigms, such as cloud services to telephony.

Some form of call center capability is often available, though many times either as a different product version or simply a higher pricing tier, so be careful before you assume you'll be getting those features. These capabilities are meant to support large sales or service desk staff and their need to route and process a relatively large number of incoming customer or user calls. That means complex menu trees, an auto-attendant for routing, and service queues. You'll probably find you need interactive voice response (IVR) capabilities, and that should be backed up by support for a live operator or some other type of human intervention.

The majority of plans are loaded with a great selection of features that can come in handy when you are making or receiving calls. Many providers offer over 30 features included in the low monthly fees. These include basic call management features such as call waiting, call forwarding, call blocking, caller ID name, do not disturb, and voicemail. More advanced features such as the voicemail to email feature let's you access your messages at anytime, even when you are away from your home, simply by checking your email inbox. Distinctive ringing, additional virtual numbers, and Smartphone Calling App's are other examples of more advanced features that can be useful.
