VoIP (Voice over Internet Protocol) phones is much cheaper than traditional land lines, even for large VoIP networks. They are also less susceptible to outages, which can be a great benefit if you use VoIP for your business.
A VoIP phone system or VoIP phone uses voice over internet protocol technology for placing and receiving telephone calls over an IP system, like the Internet. The VoIP service operates between two servers and does not use dedicated telephone lines. VoIP telephony utilizes digital protocols to carry voice data over the Internet in the form of packets. These packets are routed to the right destination by the use of routing protocols and are then received by the receiver as telephone calls. This process is much like how an e-mail client sends a message to another user, but instead of using a physical mailbox, it uses the Internet to send messages.
There are several advantages to using VoIP systems.
The main advantage of using this type of technology is that it allows you to interconnect your VoIP systems with your internal network. You can route calls from one phone to another without the need to share or allocate telephone numbers. You also have the ability to make calls from your voice mailbox and receive faxes from any fax machine in the office. Many businesses have voice systems, but they are limited to being able to send faxes and receive faxes over the public switched phone network. Many business offices now use IP phones, which offer all of these features and more.
There are several disadvantages associated with VoIP phones.
In some cases, there is congestion on the network that makes it difficult to send and receive calls. Many internet service providers have tried to solve this problem by introducing congestion free traffic classes, which can greatly reduce the time it takes to send a call. There is also a limit to the number of simultaneous calls that can be made using a particular VoIP software program. Most telephone companies have implemented measures that limit the number of simultaneous calls, or “soft” calls, that can be made by a computer to a subscriber’s phone.
One of the most common problems that people experience with VoIP phones is the session initiation protocol. This is a feature of many VoIP systems that is designed to avoid retransmissions of the same message when two different calls go through. This can cause the caller to miss important calls and even result in long-term dropped calls. For this reason, most VoIP phones have a “SIP off record” feature that prevents repeats from happening. However, as VoIP software programs continue to improve in functionality, more advanced session initiation protocols will be available in the future.
Many VoIP phones require an IP address in order to function correctly. This requirement is often the result of legacy networks that use shared IP addresses and may cause users who use VoIP phones to experience problems if they move to a new network location. Newer systems are being developed that will minimize this problem while still maintaining backward compatibility for many existing IP networks.
One other major issue that many VoIP phones require is caller id. Caller id is required for the proper functioning of any telephony system and can easily be disabled or changed at any time. Some VoIP phones require separate lines dedicated for the purpose of caller id. The downside to this feature is that it might need to be configured separately for each caller, which means additional cost for the user. Some business owners may prefer to use VoIP because of the number of communications that can be conducted on the same lines, without requiring separate lines. This allows companies such as restaurants and retail stores to communicate with their customers using voice rather than the sometimes-costly Internet connections currently available.
- All of these features, however, do come with a price.
- VoIP phones are more expensive than traditional phone services because of all the extra features and extra equipment required to make them functional.
- Even the least expensive VoIP services include a landline number, which have to be paid for by the phone service provider, and a mobile device that must be purchased separately from the VoIP service.
- If the business owner does not want to pay the increased cost of VoIP phones, he or she may wish to consider buying a VoIP phone from a different service provider.
