    The subject line of the email begins with the following text: VoIP Quality Report


If an Issue Occurred In the Past

...

  • Constantly monitor the Internet connection between your system and the network your affected agents are using and the LiveVox application.
  • Provide the following information (at a minimum) about the occurrence to LiveVox:
    • Timestamps
    • Call examples
    • Number of affected agents
    • Number of affected locations
    • How the agent was establishing the audio path

Methodologies

The following sections describe the steps that LiveVox performs depending on the test results displayed in the VoIP Quality Report email.

titleRoute Test Results

Introduction: Route test measures the speed and route a data packet takes to a destination server.

Info
iconfalse

This test works by sending test packets of data to a specific destination address and records each device (represented as hops) passed by the data on its journey. A minimum, maximum, and average response time measurement is recorded per hop.

Objective: Number of hops must not be more than 20. 

Test: In the Route Results section of the email, click the Detailed Route Results link. The My Connection Server page appears. In the Route Test section on the page, check the number of hops.
Route Tests Section

Info
iconfalse

In this image, the number of hops is 14, which is not an issue.


Issue Resolution: If the number of hops is more than 20, LiveVox does not escalate the case. You must contact your Internet service provider to identify the cause of the issue. 

Info
iconfalse

If you want LiveVox to pursue the case, the case will be is escalated while ensuring that the route result is noted.

titleVoIP Test Results

Introduction: VoIP test emulates VoIP calls by using the selected codec and number of lines to provide a Mean Opinion Score (MOS) based on a combination of results. 

Info
iconfalse

MOS is a metric to assess the overall quality of a call. 

Objectives:

  • Average round-trip time (RTT) is must not be more than 200 ms.

    Note
    iconfalse

    If the agents are in locations such as India located in countries outside the United States of America, such as India or the Philippines, the maximum average RTT should must not be more than 300 ms.


  • Upstream and downstream jitter is must not be more than 20 ms.

  • MOS is must not be less than 3. 

    Info
    iconfalse
    • Minimum MOS: 0 (worst)
    • Maximum MOS: 4.2 (best)


  • Upstream and downstream packet loss is not 3%-4% because must not be more than 3% because this could affect audio quality.

Test: In the VoIP Results section of the email, click the Detailed VoIP Results link. The My Connection Server page appears. In the Summary section on the page, check the values for the aforementioned parameters.
 Summary Section

Issue Resolution: If an objective is not met, LiveVox will does not escalate the case. You must contact your Internet service provider to identify the cause of the issue. 

Info

If you want LiveVox to pursue the case, the case will be is escalated while ensuring that the VoIP result is noted.

titleFirewall Test Results

Introduction: Firewall test checks if outbound communication to the LiveVox application ports is permitted by your network devices. 

Info
iconfalse

Outbound communication to the LiveVox application ports is required for the platform to function correctly. Blocked ports may result in the loss or degradation of service.

Objective: Ports are must not be blocked.

Test: In the Firewall Results section of the email, check if the ports are reported as blocked.

Issue Resolution: If the ports are reported as blocked, contact the LiveVox Customer Care Team.

Info
iconfalse

The following table describes the standard use of each port.

PortUse
TCP 443Web traffic (HTTPS).
TCP 8080WebRTC traffic (web and audio paths established simultaneously).
UDP 5060SIP-Trunks when your PBX does not support encryption with TLS version 1.2.
TCP 5061SIP-Trunks when your PBX supports encryption with TLS version 1.2. Also used for sLVC (99.9% of clients use the Secured accounts). 
TCP 5071sLVT (hard-phones supported: Polycom VVX-310 and SoundPoint-331).
UDP 15000-30000RTP streams (audio).



Note
iconfalse

A blocked port can be considered to be the cause of an the issue depending on how you have implemented the port your voice implementation (that is, how you have established the audio path). If the port that is intended for establishing the audio path is reported as blocked, you are asked to enable the port. For example, if you are establishing cannot establish the audio path via WebRTC and the test result shows that the port TCP 5061 8080 is blocked but TCP 8080 is enabled, this is not the cause of the issue, you are asked to enable the port.


Warning
iconfalse

If you are asked to enable a port, ensure that the port is enabled only in the outbound direction.
