Posted by Daniel Noworatzky on Feb 13, 2019 10:50:00 AM

VoIP protocols, part 1

When we talk about VoIP, the most prominent and widely used protocol is Session Initiation Protocol (SIP). But SIP doesn’t operate alone. There are many other protocols involved in IP telephony that function alongside SIP or even in the place of it. It is important for a telecom engineer to be familiar with these protocols, to know what they do and how they can be leveraged on the telecommunications network.

In this article, we’ll look at the companion protocols that work in conjunction with SIP. In a future article, we will focus on protocols that can be used as alternatives to SIP.

VoIP and the law: Your rights and obligations

Posted by Daniel Noworatzky on Jan 30, 2019 11:50:00 AM

Posted by Daniel Noworatzky on Jan 16, 2019 10:49:00 AM

Product Review

In today’s fast-paced business world, every minute counts. It can be time-consuming to schedule telephone conference meetings, book meeting rooms equipped with conference phones, and wait for everyone to arrive before beginning. Instead of having the participants come to a meeting, with Yealink’s CP930W conference phone, you can bring the meeting to the participants!

Imagine going to the procurement department, or to the sales department, to meet with colleagues there and bringing your CP930W conference phone with you. Free of wires, you can place it anywhere within your DECT coverage and begin a meeting. You could even make the warehouse an impromptu telephone conference meeting room.

Demystifying codecs, part 1: Digitizing the human voice

Posted by Daniel Noworatzky on Jan 9, 2019 10:48:00 AM

Understanding how codecs work

One of the most abstract attributes of Voice over IP (VoIP) is the codec. We may wonder which codec to use in a given situation. Of course, there are general industry guidelines that help us make such decisions, but it can be unnerving to blindly follow recommendations without knowing why. For example, why should G.729 be preferred over the G.711 codec for WAN links? Why should I use G.722 when I don’t have an issue with bandwidth? What are the advantages of iLBC and Opus over the G series of codecs and when should I use them?
