Many businesses today are either thinking about or have already begun replacing their existing phone service with a voice over IP (VoIP) solution. Today, VoIP services and systems are well established with both small and mid-sized businesses and large enterprise customers. For example, VoIP penetration among US businesses was 42% at the end of 2009 and is expected to reach 79% by 2013.
The following are the top 10 questions customers inquire about moving to VoIP:
1. What are the benefits of VoIP?
In the early days of IP telephony, the initial appeal of VoIP was toll savings. While toll savings remains a good reason to switch to VoIP, there are others, such as:
- Reduced costs – Unlike traditional telephony, VoIP utilizes the existing network infrastructure for system installation. This saves thousands of dollars by taking advantage of the investments already made by a company.
- Ease of management – IT staff can often manage the VoIP phone system because it runs over the company’s Internet connection or data network. This enables them to perform routine tasks such as setting up voicemail boxes, adding or deleting users, as well as activate other features at no additional cost, while outside vendors could charge upwards of $300/hr for the same tasks.
- Mobility and portability – Special features enable employees to work remotely while still accessing advanced call handling and additional features as significantly reduced capital costs. Added benefits include flexibility, scalability and reliability.
2. Can I implement VoIP and keep my existing PBX?
The biggest factor influencing the answer to this is whether your existing PBX can be interconnected to a VoIP gateway. If it can, you will need a VoIP gateway installed on your site in order to IP-enable your existing PBX. When it’s time to replace that PBX, you will most likely want to replace it with an IP PBX as well as IP phones.
3. What charges should I expect for my VoIP services?
Expect one-time, non-recurring charges that typically include an installation and account set-up fee, as well as a charge for setting up an IP trunk or channel between your site and your provider. Monthly recurring charges are for your phone calls.
Occasionally providers offer bundles of minuets (ranging from 500 to unlimited) for a fixed monthly fee, and then charge for calls exceeding the limits of your plan. Others require monthly fees for the trunk or channel then charge each call at a rate determined by call destination or duration. Generally, service providers offer lower rates for higher call volumes.
4. Are there any other service charges I should plan for?
Each service offered by a VoIP service provider (including but not limited to: hosted PBX, US and Canada toll-free numbers, local numbers (DIDs/DDIs), and conference call service) typically comes with one-time and monthly recurring charges.
5. What is hosted PBX and what are its advantages?
A hosted PBX system delivers the functionality of a traditional on-site PBX but as a service. The subscriber does not buy the equipment and is able to use regular phones. In addition to cost savings, another key benefit of a hosted PBX is that it can make any office virtual by sending calls anywhere – enabling employees to receive calls through their company’s main business number whether they are working on the road, at home, or in the office. Features such as “follow me” allow calls to try several different numbers for each employee.
Because the hosting company houses the equipment and is in charge of updating and expanding the technology required for its subscribers, a hosted PBX greatly reduces upgrade costs and complexity. As an added bonus, service providers typically have thousands of extensions spread across their client base, making them scalable to any size and capable of adding additional extensions without taxing bandwidth. Simply put, hosted PBX is a service that requires no capital investment, offers a predictable monthly operating expense, and has a lower total cost of ownership than premises-based PBXs.
6. Is there any other special equipment required to move to VoIP?
That depends on a few things, the first being whether you choose to carry on using your existing PBX; if you do, a VoIP gateway is needed to digitize analog voice calls from your TDM PBX. Small or mid-sized businesses that do not have a PBX will need a VoIP device or analog telephone adapter (ATA), as well as a router or VoIP gateway.
A critical aspect is the design of your local area network (LAN) and its equipment components. In a VoIP environment, your LAN becomes part of your telecom infrastructure. You need to be sure your firewall, router or switch and any other equipment can handle VoIP and be set to deliver the Quality of Service (QoS) required for VoIP and give priority to voice traffic.
7. What faxing services are provided over VoIP?
Faxing over VoIP can be both challenging and unpredictable. For this reason, heavy faxing businesses should take into account keeping a PSTN line specifically for their fax machine. Companies that from time to time fax up to a 4 page document will work just fine if their VoIP service provider supports certain codecs that allow faxing. Certain VoIP providers are capable of accepting your fax for you, and then sending it via email in a PDF format.
8. How is the quality of VoIP service?
Today, VoIP providers rely primarily on highly-reliable Internet routes from Tier 1 – and some Tier 2 – carriers to move their traffic. Top-quality network equipment and solutions are developed for customers of companies delivering business-class VoIP. Ideally, your VoIP traffic should move along routes with the least number of “hops” – everything below 200ms for a VoIP packet is considered adequate.
That being said, there are some issues that affect voice quality in VoIP, including:
- Bandwidth – always topping the list of factors that affect VoIP quality, don’t expect great quality with a dial-up connection, however, a broadband connection is suitable provided it is not shared with too many other applications.
- Hardware – poor quality equipment is more often than not the cheapest. For that reason, it is essential to have as much knowledge and information as possible on an ATA, router or IP phone prior to investing on or beginning to use it.
- Location of your equipment – often VoIP equipment can interfere with each other, producing noise and other problems. For example, your IP phone frequency could hinder other VoIP equipment. This is due to electrical feedback.
VoIP transmits voice data packets in a compressed form so the transmitted load is lighter. The compression software used for this are called codec’s. Each codec is designed for a specific use. If a codec is used for a communication need other than that for which it is meant, quality will suffer.
9. What kind of support can I expect?
After making the choice to switch to VoIP, one of the most important things to consider is the quality of service you will get from your provider, including assistance and training with technical issues and customer support.
Know whether a provider offers 24/7/365 tech support or just 8-5? Do they offer on-site support? Are there specific response and resolution times for different outages? What are the associated costs of these issues? Fortunately, the majority of service problems in a VoIP environment can be detected and resolved remotely. Another important yet frequently overlooked issue is the attitude and capabilities of a provider’s technical team. Find out the size, certification and training of their support staff as well as their overall service philosophy to get a better understanding of how they will handle your technical troubles.
10. What other factors should be considered in selecting a VoIP service provider?
Customers should be careful to distinguish between residential and business focused providers. Residential VoIP providers, for example, typically do not understand the demands or expectations of business-class VoIP; likewise, they do not use the same equipment or carriers. A VoIP service provider focused only on business customers will be more likely to truly understand and address your business’ needs.
The VoIP service provider you select will be the key to whether and when your business realizes the cost, productivity, and other benefits of VoIP services and solutions.
