Many factors lie behind VoIP Quality of Service. Such issues as latency, jittering, choppy audio, echoes and crackling sounds occurring during calls are being met with ongoing solutions that continue to evolve and that will soon make these issues hobby horses of the past. As the Internet improves with more bandwidth offered over better configurations of wireless connectivity and optical cable, VoIP networks will move into a position to become the communications standard for most businesses and residences alike.
Latency As Packet Loss
Audio voice is digitalized into bits and bytes for through the Internet. As all other data, collections of these bits and bytes are broken up into packets. Each packet has identifying codes of various types for addresses and corrections. The packets may find different routes to reach their destinations where they are placed together according to their identifying addresses and then may go through other processes of decoding.
There may packet loss or delays in the amount of time it takes for packets to arrive to their destination in VoIP networks. Such delays may create latency from the time you speak into the phone and the time your voice is heard on the other end. Latency is usually measured in milliseconds and the normal, average acceptable rate has been 45ms. VoIP may average an acceptable 75ms to 100ms without service disruption.
Overseas calls present different challenges many times having to do with satellite transmission. They may easily show latency rates of 250-350ms. With major investments in satellite technologies as an ongoing affair, we can eventually expect improvements that could reduce such long rates.
Latency issues can be met by prioritizing VoIP traffic and also having a better VoIP router. White Label can advise you of VoIP-priority routers that have specific QoS settings and that can prioritize your VoIP transmissions. Your bandwidth can be automatically managed to more effectively avoid bottlenecks that may occur in different areas of your transmission setup. Unexpected traffic bursts can be intelligently addressed across various switches in the rough to allow the heavy bandwidth video conference.
Jitter and Choppy Reception
Jitter is related to latency and is often used to describe different packets received over transmission with high and low latency rates. Technical ways of dealing with it is through improved multi-path capillary routing of packets as opposed to shortest-path routing. There is also use of a jitter buffer that can store packets until they are ready to be received in full.
Echoes and Crackling Sounds
These are usually caused by electromagnetic interference. Sometimes the handset volumes used by your customers may be turned up too loud or there is a clash of impedance levels with low-quality handsets interfering with other electronic devices. Inadvertent splitters or low quality phone lines in the call circuits can also cause impedance mismatch.
Customer Integrated Access Devices connected to DSL lines could have weak or clashing electronic devices such as wrong power supplies or weak batteries. Alarm systems are also known to provide electrical interference, causing static or crackling sounds across customer caller ID lines. In resolving these problems, White Label Communications has acquired wide references of experience to help you resolve these issues.
Quality of Service Protocols
The solution to providing excellent Quality of Service is not simply increasing bandwidth. It is having smart and efficient management of the VoIP service that we at White Label Communications can provide for your use or your customers. The services can be integrated or differentiated. We can adjust them to emphasize individual or aggregate flows. Network resource reservations can be arranged with a per-flow basis using the ReSerVation Protocol (RSVP).
We have streamlined testing services to measure such activities as the latency rates, jitter and packet loss and can provide you will cost-effective resolutions of these matters. Your ISP is just as important as your building’s wiring and we check these for efficiency.
By building efficient and scalable lines of service, we are able to insure against data loss for your customers. With our scalable SIP trunks we can easily re-route calls to such alternates as branch offices, voice mail boxes or cell phones. Disaster recovery of packets during service disruptions becomes reliable and easy to maintain consistent delivery of network data.
Quality of Service technologies continue to improve with VoIP networks. With White Label Communication, you can be assured of delivering the best in high quality communications to your customer base.
