Network guidelines
• Quality-of-service/voice-quality issues
– A customer using the Internet to transport the voice can expect some voice-quality issues. Check
the connection’s bandwidth utilization of the connection (and recommend that the customer
increase the bandwidth). Using Esi-Networx or the PING and TRACERT utilities will also help you
to narrow the problem down to the unreliable path the packets are required to take while moving
across the Internet.
– If the customer is using a dedicated or point-to-point connection, Esi-Networx can check both the
bandwidth utilization and the end-to-end latency of the line. Normally, the connection will become
saturated due to increased data traffic. Refer the customer to his/her SLA1 and/or CIR to
determine the point-of-contact, to get the issue corrected.
– Use Esi-Check to monitor the quality of the IP connection over time. The user can instantly view the
quality of the link by noting the color of the Esi-Check icon in the Windows system tray.
