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.
