Disadvantages of VoIP

Disadvantages of VoIP
Published on:

Everything that has an advantage has its disadvantages. VoIP Telephony PBX PBA Doha Qatar is not exempt from this rule.
Here are the downsides associated with the VoIP service you need to be aware of:
Reliable Internet Connection Required
Latency and Jitter
No location tracking for emergency calls
Reliable Internet Connection Required
For starters, your VoIP service is only as good as your internet connection. If your network bandwidth is low, the service is bound to suffer.
VoIP doesnít use as much bandwidth as you might expect. Itís essential that VoIP devices receive low latency on your network. Each device should have at least 100 kbps upload speed available. A good connection has less than 70ms ping and jitter, which measures the latency and stability of your internet connection.
The bandwidth your business needs will depend on the number of concurrent calls you plan on making. The best way to determine this is to run a bandwidth test on your current network.
Latency and Jitter
Aside from speed, there are other connection issues any internet-based technology can face: latency and jitter.
When communicating online each message (whether it be email, video, or audio) is broken into bits of data called ìdata packets.î These packets are then reassembled at their intended destination to create the original message.
Latency and jitter are when these data packets either hit delays in transmission or get improperly re-assembled. These issues might not even be with your network; major internet backbones modify data routes to deliver traffic reliably, fastest path to a destination. These changes happen automatically with no involvement on your part.
Why latency and jitter occur
Poor Internet connection ó VoIP requires more bandwidth than regular web surfing. So, if you find your Internet speed wanting, it might be a good time to have an honest conversation with your ISP.
Inadequate router ñ For VoIP service to run smoothly, it needs a specialized VoIP router. This is a router configured for packet prioritization so that it affords higher priority to voice traffic over data.
