The Beginner Files: What is a Call Path?

Call path analysis and how it works for you 

Call path is the journey call’s ride to connect and reach recipients. It is the fundamental process of unified communications, and it’s also where several productivity-halting problems arise. For this reason, many in the UC industry are familiar with call path, but for those of us who aren’t as tech savvy, it is more difficult to understand.

I happen to be one of those less technologically acute people. I study finance and am an intern for Vyopta, a company that analyzes UC products and challenges me to adapt. While I am interested in technology I lack prior experience in UC even though it’s something I use every day. This is a great thing for me as I’m learning something new every day but this industry as a whole has a steep learning curve. It took me a while to grasp the ‘language’ of the UC industry, but after internalizing many acronyms and terms, I gained a basic understanding of how UC functions.

The call path is no different. In this blog, I’ll address what a call path is in simple-to-understand terms for those of us less familiar with UC. Additionally, I will touch on how issues can arise in a call path and how we can solve them.

The life of a call

Since the days of planning a hang out with your friends via a landline phone, the steps of making calls has been ingrained in our brains.

Dialing a number is the first step in the call path, which tells the network’s internal systems your end goal: who you want to reach.  This means the endpoint will communicate with the call control to help find the desired endpoint. Think about the switchboard operators that you might have seen in movies or that your parents told you about. Call control today is like that, but considerably more sophisticated.

Call control is the nervous system of unified communications. It has several important functions, namely setting up the calls between endpoints, and enforcing certain security protocols.

Dialing back to the call path, once the dialer’s endpoint communicates with call control, it dials the recipient of the call. At this point of the process, the last step is for the recipient of your call to pick up. Once your request is received, video, audio, and content are exchanged between the two participants.

Issues that arise in call path 

Errors existing in the call path affect your call quality. The most frequent issues are packet loss and jitter.

Packet loss occurs when content is sent through the network at a greater rate than a router can handle, thus the network has to drop packets to make up for this discrepancy. Jitter refers to the variation in the delay of how packets process through the network. Imagine…some…one…talk…ing…to…you…like…this… Annoying, right?

Both of these complications have detrimental effects to a business’ flow of communication whether it be internal with an executive or external with a potential customer.

Our solution to call path issues

Vyopta is a business that exists to alleviate issues that arise in UC platforms — including those related to call path. In fact, Vyopta software allows you to undergo a call path analysis through our software vAnalytics. vAnalytics allows seeing network latency from the beginning to end of a call. Additionally, an ‘EKG’ of call performance is presented to users, enabling them to see how well a call performs in real time. Lastly, vAnalytics provides data from specific endpoints, bridges, and gateways to allow IT to identify where problems arise quickly.

We provide a platform that can quickly and accurately diagnose issues in a call path. Don’t let call path issues become a hindrance to your business environment. To find out more about how Vyopta can help improve your UC environment, visit our website and checkout our demo.
