VoIP needs power
Unlike PSTN phones, you need to plug your modem, router or other VoIP hardware into the power supply for it to work. Clearly, this means that if there is a power failure, your phones go down. A UPS (Uninterruptible Power Supply) can help if you lose your primary power source as it will kick-in and keep your system running.

Shared connections
In a business context, it denmark telegram is likely that you will be deploying VoIP over a broadband connection that is also used for other things such as server connectivity, email and downloads. This means that VoIP will only be allocated a share of your total bandwidth and may suffer at peak times, resulting in lower call quality.

It can be tricky to ensure adequate bandwidth is always available so it is a good idea to try not to use your internet connection for things other than VoIP when you are actually on a call. In addition, some businesses will opt for a dedicated line for VoIP so that there is no conflict. There are other priority and QoS (quality of service) mechanisms which can assist here.

Security risks
As with other internet-based systems and technologies, security is a significant concern when it comes to VoIP. The most relevant security issues concerning VoIP are viruses, malware, denial of service attacks, identity/service theft, phishing, and call tampering.
