If you are a voice network engineer, then it has probably happened to you. Your SIP server is all set up and you have plugged in your IP phone. Its lights come on, its screen is activated, you see the loading icon rotating, and then… nothing. For some reason, the phone will not register.
IP phone registration issues are, unfortunately, not uncommon. In this article, we examine the most common causes of registration failures, and best practices for troubleshooting and resolving them.

Dealing with pesky cords is a common frustration of conference phones. If you want to place the phone in the middle of a conference room, you either need an electrical outlet located in the middle of the floor, or you need to bring in an extension cord. And then you need to be careful not to trip over it!
That’s why we love the Snom C620 conference phone. It uses DECT 6.0 technology for a completely wireless conferencing experience. Even the detachable microphones are cordless, allowing for more effective collaboration without the frustration factor. In this article, we take a look at this robust and flexible conferencing device.

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.

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.
