Factors That Impact VoIP Call Quality
To thrive in today’s Information Age, businesses need the right and reliable equipment for executing their operations smoothly. As technological realms expand, managing deployments of software and hardware in enterprises has become a convoluted task. Among the biggest concerns in today’s business communication landscape is Voice Over Internet Protocol (VoIP) services. Issues like voice quality and bandwidth often threaten to overshadow the myriad benefits that VoIP services bring to the table. Let’s delve into the various factors affecting VoIP call quality.
- 1. Bandwidth and Network Parameters
Voice quality can take a significant hit in the case of shared networks, especially as network load increases. Establishing high priority for voice packets over data packets in network transmission can considerably enhance your network load’s performance.
Several other facets of voice communications also play their part in affecting voice call quality. These include the call success ratio, call setup times, and call setup rate. Furthermore, the type of protocol used such as H.323 or SIP also influences VoIP performance as different processes are handled distinctively by each protocol.
2. Codec Usage
VoIP or IP telephony in every business environment leverages an audio codec to compress the audio signals on one side and decompress them on the other. VoIP call quality is deeply dependent on the type of codec deployed. The higher the data compression, the lesser will be the data size transmitted over to the other end. Also, different codecs can accommodate varying target compression rates which in turn requires more CPU resources to execute complex codecs, affecting VoIP call quality.
3. Jitter Cycle and Jitter Buffer
Wireless connections often grapple with issues such as jittering. Codecs send packets with equal spaces, and ideally, these need to arrive in the same order and similar spacing at the decompression level. However, network delays at the packet level could cause the packets to reach at different time intervals and in a jumbled manner, negatively impacting VoIP call quality. To nip this problem in the bud, jitter buffers are introduced to induce a calculated delay before dispatching packets for decompression.
4. Usage of Outdated Equipment
The use of obsolete routers, cable modems, and firewalls can lead to poor VoIP call quality. Updating router software or replacing old equipment can augment VoIP call quality. Working in tandem with the VoIP service provider can help diagnose these issues more effectively and address them promptly.
5. Echo Issues
The conversion of IP media to digital/analog signals forms a crucial part of IP telephony. This conversion process can lead to echo generation at various network points. Hybrid and Acoustic are the two broad types of echo generated in the network. Monitoring echo is usually a tough task but certain vendors offer echo cancellation at the gateway level with the help of hardware and software modules.
Most of the VoIP-related issues mentioned above can be tackled effectively with specialized tools and equipment, ensuring no hiccups with VoIP services. As a result, businesses can enjoy unimpeded and smooth operations, building a robust working environment.
