Know your protocols: VoIP protocols that work together with SIP

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.

What's innovative about the Yealink DECT CP930W conference phone

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.

How to troubleshoot voice quality problems in VoIP phone systems

Posted by Daniel Noworatzky on Nov 21, 2018 10:46:00 AM

How to deal with jitter, packet loss, latency and signaling delay

Some of the most difficult issues to troubleshoot on a network are failures resulting in a degradation of service, a slowdown in speed, or intermittent connectivity, as opposed to a complete disruption in service.

When it comes to troubleshooting issues involving VoIP, this becomes even more acute. Intermittent, low-quality, and metallic-sounding voice, as well as erratic connectivity between VoIP end devices, are all network problems falling into this difficult-to-diagnose category.

Almost all such malfunctions are due to a faulty implementation (or lack thereof) of quality of service mechanisms. In this article, we will look at some of the most common failures of this type, what they sound like, and what should be done to verify and rectify the problems.

How to resolve one-way or no-way audio on VoIP calls

Posted by Daniel Noworatzky on Jul 4, 2018 3:13:00 PM

Unlike conventional telephony infrastructure, which was developed and tailored to be used exclusively for voice, today’s telecom networks accommodate a multitude of different data traffic types, of which VoIP is just one of many. Because of this, it can be challenging to adapt a network to accommodate voice.

One of the most common challenges involves a technology called Network Address Translation (NAT), which for data networks has been a godsend, but if not configured carefully, could cause problems for voice applications. In particular, NAT is a common cause of one-way and no-way audio on VoIP calls.

In this article, we dive into how NAT can impair voice sessions, cite some common symptoms that indicate NAT may be at the root of your call audio problems, and address how to resolve the issues.

How SIP enables workforce mobility

Posted by TeleDynamics on Feb 14, 2018 4:02:00 PM

A decade ago, it would have been rare to meet someone who could carry out their profession from anywhere. For most, “going to work” involved physically going to a place of business. Today, because of the swift development of collaboration tools and the ubiquitousness of connectivity to the internet, working from anywhere is not only an option, but is often preferred by both employer and employee. Studies have shown that a mobile workforce tends to be more productive and experience higher job satisfaction.

Voice over IP (VoIP) technology is one of the major facilitators of employee mobility. Here we highlight some of the functionalities and tools that allow for a seamlessly mobile workforce.
