5 things to look for when it comes to the smooth operation of your IP phone line

The quality of your communications depends on the proper functioning of your IP phone line. Based on your choices, this could pose a problem. It’s therefore preferable to check the following key elements, which will let you benefit from the best possible line quality, and how best to make the most of it.

1. The internet connection

Most IP phone lines are designed for browsing the Web, not for use as a telephone line. Voice transmission requires different internet protocols and more complex searches. Our advice : To make sure you have a high-quality IP line for your phone calls, make sure you choose high-performance wiring and speed.

2. Scrambling

Voice scrambling is a very common problem on static or packet-switched networks. The information – i.e the voice – is divided into packets, and each packet can travel along a different path from the transmitter to the receiver. When the packets arrive at their destination in a different order than the one they were sent in, it results in poor or scrambled audio quality. Our advice : Use buffers that temporarily collect the arriving packets in the correct order and thus minimize variations in quality.

3. Latency

Latency is characterized by the delay between the moment when the speaker speaks and the moment when the listener hears his or her voice. This latency can produce an echo effect. 3 types of latency are commonly found in IP lines : 1. Prolongation delay: A fibre optics network naturally has a delay of about 70 milliseconds. Although practically imperceptible to the human ear, if takeover delays are added to it, it can result in a noticeable degradation in the conversation. 2. Takeover delay: These delays can have a sizable impact on phone networks, but they’re a much more serious problem in the case of “packet” environments. 3. Queuing delays: When the packets are placed in a queue, that causes delays. This type of delay occurs when the number of packets sent exceeds the management capacity of the interface within a given time period. Our advice : Privileging IP phone traffic over the network significantly improves latency and scrambling.

4. The router

Unsuitable equipment is one of the most common causes of poor quality when it comes to IP phone services. Many SMEs use their internet connection both for phone calls and for database management. Without a router configured to prioritize packets, call quality can be affected by other users on the network. Our advice : Install a specialized router designed for IP telephony. A specialized router prevents network overload while giving priority to phone calls.

5. Your internal network

Many companies unfortunately don’t sufficiently consider the demands of excellence when it comes to the quality of their IP phone communications. If you decide to manage telephony and databases jointly, you run a great risk of encountering problems with call quality. Our advice : Configure your network optimally. It’s one of the easiest and least expensive problems to solve. A specialized router will generally solve the problem.

To overcome all these problems once and for all, the best option is to count on the reliability of a specialized software such as Studio. This innovative phone system management interface will maximize your business communications management!
