Use IP Ping Tool to Diagnose Network Issues

This topic describes how to use IP Ping tool to test if Yeastar P-Series PBX System can reach a specific hostname or IP address, and introduces the test result.

Background information

Based on the Internet Control Message Protocol (ICMP), IP Ping is a network tool to determine if a destination server is accessible and estimate how long a packet takes to send and receive data from the server.

If you are suffering from the followings, you can use IP Ping to diagnose:
  • Network issues.

    For example, if you can not make calls, you can use IP Ping to check if the PBX can access external network.

  • Poor VoIP call quality.

    For example, if you are experiencing echo, buzzing, or latency during a call, you can use IP Ping to check jitter and latency, or if there are any packet loss.

Procedure

  1. Log in to PBX web portal, go to Maintenance > Troubleshooting > IP Ping.
  2. In the Target Host field, enter the target domain or IP address.
  3. Click Start.
  4. Click Stop as your need.

Example1: A successful Ping
start...
PING 192.168.6.11 (192.168.6.11): 56 data bytes
64 bytes from 192.168.6.11: seq=0 ttl=64 time=8.853 ms
64 bytes from 192.168.6.11: seq=1 ttl=64 time=0.778 ms
64 bytes from 192.168.6.11: seq=2 ttl=64 time=1.394 ms

--- 192.168.6.11 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 0.778/3.675/8.853 ms
The above example shows the followings:
  • The device sends 3 ping packets and receives response for all the 3 packets.
  • The ping packets' size are 64 bytes.
  • The TTL value is 64, which indicates that packets are always forwarded to the same region.
  • The time indicates that how long it takes to receive an Echo Response message after an Echo Request message is sent. This parameter can be used as a reference to determine whether the network is congested.
Example2: A failed Ping
start...
PING 192.168.7.2 (192.168.7.2): 56 data bytes

--- 192.168.7.2 ping statistics ---
60 packets transmitted, 0 packets received, 100% packet loss
The above example indicates that there is an issue of either the connection or the target device.
