VoIP Phone Benefits
If you are looking for a phone system for your business you no doubt already know that finding the right system at the right price can be a difficult task. Phone systems can be a costly investment but one benefit of VoIP phone systems is that they allow you to save some of this expense by eliminating setup and installation fees as well as preventing the need for any on premise server equipment and maintenance.
Gone are the days when VoIP technology could not match the voice clarity of traditional phone networks. Today you can make calls anywhere in the world and no longer be able to notice any difference at all with a significant improvement in the call quality and a decrease in the number of dropped calls meaning no more strained business relations and more satisfied customers.
The virtual nature of VoIP mean you no longer have to deal with the hassle of registering and setting up country specific phone numbers, instead you can ensure you can be reached on the same business number wherever you are. This is vitally important for any business owners who are required to travel for meetings and other appointments and may be worried about picking up calls on the move.
As with any organization, even with a team smaller in size the output and productivity levels must still remain high if an organization is to grow and hit KPIs. This means it is even more important that the phone system you choose has features that help your staff in as many ways as possible and additional features of VoIP phones such as unified video and voice functionality and customizable touch-screen displays can be vitally important.
As well as the convenience and cost-saving benefits of converging your telephone and Internet systems onto one network, VoIP also brings access to the kind of advanced phone service features that until a few years ago only large corporations could have afforded with a traditional telephone system.
Business VoIP systems provide a great degree of customization, allowing you to piece together just the features you want or need for your particular requirements – without having to pay for bundled features that you aren’t going to use.
Advanced voicemail / Click to call
The difference between the old-school answering machine and VoIP-enhanced voicemail perfectly illustrates how VoIP systems take conventional telephony concepts and bring a whole new level of flexibility and efficiency to their implementation. With VoIP voicemail, you’re never more than a click away from calling someone back directly and easily – but you might also prefer to get each voicemail emailed to you as an audio file attachment, or automatically transcribed and delivered to you via text message or email. You also have the option of tracking missed calls from your email, and calling them back directly from within your email interface: a feature known as ‘click to call’. You can even incorporate fax into the equation, sending and receiving ‘virtual faxes’ as PDFs.
From this software interface you have immediate access and control over every aspect of your business phone system, such as voicemail, call logs, contacts databases, programming greetings and messages, setting up conference calls and directing traffic. From here those employees set up as administrators can also manage billing and further customisation of the phone system as needed.
Find me/follow me
With VoIP you can assign each employee or member of the team a single ‘virtual extension’ number rather than everyone needing a separate number for each office, mobile or home office phone. Calls to a virtual extension can then be set to ring all of your phones simultaneously, or in order, and also how to handle a missed call. You can choose if a call should go to voicemail or be passed to another extension. The virtual extension also works on outgoing calls, so whichever phone device you’re actually calling from or where you are, the receiving caller ID will show your number and you can present a consistent front to clients, suppliers and customers.
Also sometimes called a digital or virtual receptionist, an auto-attendant is a voice menu system that greets and guides callers through numbered options so that they can be transferred to the relevant departments or extensions within the company.
Interactive Voice Response (IVR)
Callers are greeted by an automated voice which presents them with a number of options – they can then interact with the voice, selecting their preferred option (for example, which department they would like to speak to) using the keypad on their phone. IVR systems can handle high volumes of incoming calls, and can reduce costs and improve customer experiences by providing access to information and services 24 hours a day without the need for human staffing around the clock.
Automatic Call Distribution (ACD)
Related to the hunt group or line hunt feature in traditional PBX telephony, ACD is popular with businesses receiving high volumes of incoming calls. The ACD system distributes incoming calls amongst a specific group of phone terminals or operators based on particular criteria such as the customers selection, their phone number, the selected incoming line to the system, or the time of day the call was processed.
Allows a user to enter a call between two other extensions or between an internal extension and an outside line, either creating a three-way call or simply monitoring (listening in on) active calls. The feature can be set up to sound a warning tone to the other users when a barge-in is about to take place.
Call Me Now
This feature allows customers to call your business directly from a form or contact page of your company website, making customer communications fast and easy.
Users have the option to record, playback, download and delete any incoming or outgoing calls. This feature is often implemented on an individual extension basis, so you make this a system-wide feature or you can choose which phones or extension users have access to the record functions.
Allows users to set different sets of rules for how their business phone system functions or routes calls depending on whether incoming calls are received during business hours (day) or after hours when no-one is in the office (night). Night mode typically serves as an ‘autopilot’ mode until the day mode is restored the following morning.
This feature enables users to set up virtual meeting rooms, which can then be joined by participants on their own devices. Most service plans will allow access for 15-25 participants as standard.
Going even further than conference calling, video conference calling works the same way, but also presents all parties with a picture (live video) of the other callers.
Different Types of VoIP Phones
Once you have all of the necessary components in place to build your VoIP system, it is worth looking at the different types of phones available for businesses. There are three main types of VoIP phone; wireless, soft and conferencing.
Wireless – A VoIP phone with built in Wi-Fi or a DECT transceiver which connects to a base station or access point. Cordless office phones allows users to move freely around their workspace while on a call.
Softphones – This is in essence a software application which is installed onto a computer and equips the device with the ability to make and receive calls. Softphones are particularly useful for remote workers and even call centers because they are relatively cheap to set up and run.
Conferencing – A conference phone will usually function in the same way as an analogue telephone. However an IP conferencing phone will be used in a large office or conferencing facility where calls take place with multiple participants
With so many options available, VoIP offers a workable and practical solution for many businesses and contact centers who need a fast, reliable and high quality communications system.
How Does a VoIP Phone Work?
A VoIP or IP phone system routes your calls, voice messaging, SMS traffic and even faxes over either the public internet or a private data network rather than the standard telephone system. Most business users are attracted to VoIP solutions as a way of avoiding long-distance telephone charges.
When you a VoIP phone system, your voice is digitized into packets of information that the internet can route to the recipient, which might be another VoIP user or your VoIP service provider’s interface with the public telephone network. This allows VoIP users to contact standard and mobile telephone users seamlessly.
There are many different methods used to achieve this, however. For example, the system might use a ‘codec’ – a way of encoding audio or video signals – which is optimized for narrow bandwidths, for higher security, or for near-flawless audio clarity. Some systems can even choose which codec to use based on network performance and other factors.
Some ‘first generation’ VoIP solutions are modeled after the older phone network in order to offer fully compatible services. Other, ‘second generation’ VoIP providers like Skype provide free or nearly free traffic over a closed network of registered users. Still other, ‘third generation’ providers use a ‘federated VoIP’ system to allow dynamic connectivity between internet domains.
In terms of style and design a VoIP phone is made up up many of the same components as a typical desk phone. Advanced functions which will be explored in more detail below may include large touch screens and additional Ethernet ports.
5 Ways to Improve Call Quality
There are innumerable ‘tips and tricks’ to getting the most out of nay service, but following these 5 pieces of advice should put you well on your way to the best call quality VoIP technology can provide:
- Use a private, dedicated network rather than the internet for your internal calls. This provides more bandwidth and is also more secure.
- If you do use public internet, use a VLAN and the right switching equipment to keep data and voice traffic separate.
- Select or enable your provider’s network monitoring service. This will help eliminate packet loss and the ‘jittery’ sound quality it can produce.
- Chose equipment that supports ‘echo cancellation’ to eliminate one of the most common audio artefacts of older VoIP systems.
- Make sure your network has adequate bandwidth for your expected call volume, especially at peak times. You might even consider upgrading your network to allow for better sound quality.
VoIP systems regularly rank among the best office phone systems because of their low cost, flexibility and added features relative to traditional telephone systems. Now that you know a bit more about how they work and how to choose the best VoIP phones for you, you’re well on your way to making the most of this still relatively new technology.
