What are the biggest issues in VoIP

VoIP Voice Quality:

In simple words, the Quality of Service (QoS) is the level of ‘quality’ which is provided by VoIP for placing calls. QoS can vary depending on the technology. A good VoIP QoS is strict which allows you to make quality calls without suffering from jitters, delays, echo, noise and weird sounds. With VoIP, you essentially want to make calls just like you would with a traditional landline telephone.

VoIP can enhance its QoS but not in every case. The QoS in VoIP depends on a lot of several factors: your hardware, the VoIP service provider, your broadband connection and destination of your phone calls etc. a lot of VoIP users are enjoying high-quality calls, however there are some users which complaint of hearing Martian or having to wait before hearing an answer etc. traditional phone services have always provided good call quality hence even a slight shortcoming with VoIP cannot go unnoticed. While VoIP may offer a lot more advantages, its technology has proven to be less ‘robust’ compared to the PSTN technology. In VoIP the data is compressed and transmitted, afterward, it is decompressed and delivered. All this process has to be done is a short period of time. if the whole process takes more than milliseconds (maybe because of slow internet or faulty hardware) then the call quality will suffer adversely. This error in the process with giving rise to echo, that is a phenomenon where you can hear your voice back few milliseconds after you speak.

Nonetheless, if you have a strong broadband connection, more high-quality hardware, and better VoIP service then you can continue using VoIP without any fear. A number of VoIP service providers do things in order to prevent echo, however, it also depends on your quality of hardware and network connection.

Poor Connection:

If you do not have a good quality internet connection then you will definitely experience a bad VoIP quality and you might not like technology. Further leading to having a bad relationship with your service provider.

VoIP is Extremely Dependent on Bandwidth:

Internet telephony is another name for VoIP. Internet, bandwidth, and broadband connection are the words associated with VoIP. One thing that you must absolutely need if you use or plan on using VoIP is an internet connection. VoIP can work over a dial-up connection but it will be just too slow.

VoIP Needs Power:

You must plug in your router, modem, ATA or other VoIP hardware to the electric power so it can work, unlike the PSTN phone service. For any reason, if the power gets interrupted then you won’t be able your phone. In such cases even using the Uninterruptible Power Supply (UPS) wouldn’t help beyond several minutes.

Shared Connection:

In a business context, you would most likely be deploying VoIP over a high-speed internet connection that you will for data and communication needs such as a server, chat, connectivity, email, downloads etc. VoIP service will only get a share of your internet connection and peak times can cause insufficient bandwidth for it, resulting the quality to decline.

If you have multiple users then you will know that the number of users that are online simultaneously can make it hard to provide adequate bandwidth every time. It can damage your business’s phone line and reduce it because of poor internet connection. A good practice will be to lessen the use of the internet network for other things than the VoIP phone service.

Connection Down:

As VoIP services depend on the broadband connection, hence if the connection goes down, your VoIP phone service will go down as well. The formula is quite simple: with VoIP technology, having no internet connection means no phone service. It can be very annoying and catastrophic for your business.

Security:

Security is often a major concern for every business. Hence, security is also a major concern with VoIP services, just like it is with other internet technologies. The majority of key security problems with VoIP are identity and service theft, malware and viruses, spamming, denial of services, phishing attacks, and call tampering.

Emergency Calls:

The VoIP providers are not actually bound by any regulations to provide users with emergency calls, hence not all of them provide the services. Even though a lot of businesses are trying to make an effort to offer emergency calls with their VoIP service, this problem still remains a significant limit against VoIP.
