4 Tips for Better Voice Call Quality Troubleshooting

Posted on Oct 10, 2017 in Jeff Nolte's Blog

According to a recent survey, 90% of the time it takes to resolve network problems is spent finding its source. Without the right voice network performance management tools at your fingertips, you’ll be spinning your wheels.

To help you tackle your voice network problems, Mitel has put together some troubleshooting tips that can save you a lot of time…

Tip #1: Early Detection

The key here is a monitoring system that uses thresholds to drive performance alarms. Thresholds for voice quality, for example can be set to generate warning alarms for potential or impending problems, before any significant effects have been felt.

Tip #2: Get to the Source

When a voice quality problem happens, it typically starts from a resource problem like strain on bandwidth, or the failure of a device on the network. Monitoring tools allow you to see a pattern of device alarms around the time of a voice quality problem, allowing you to pinpoint its source faster.

Tip #3: Use Remote Access Tools

Secure access to remote devices is key to successful troubleshooting. However, using a VPN can be costly and others options are cumbersome, requiring your network admin to manually open and close the firewall. Mitel Performance Analytics uses a locally installed probe to access devices, so there’s no need for a VPN or cumbersome firewall modifications. Access is single click and cost effective.

Tip #4: Troubleshoot Directly from the Handset

Voice quality problem to resolution time is faster when you can launch an IP traceroute directly from the handset. The Mitel Performance Analytics dashboard can support this for calls generated from MiVoice Business, along with a range of additional tests, including ping, MTR, iftop and DNS lookup.
