View source for Latency

You can test the latency of your internet connection with [[ping]] or [[traceroute]]. For example: 

 $ ping -c 1000 -i .2 sip.ca1.link2voip.com

When the test is done, you will see something like: 

 --- sip.ca1.link2voip.com ping statistics ---
 1000 packets transmitted, 1000 received, 0% packet loss, time 204829ms
 rtt min/avg/max/mdev = 26.071/37.636/458.223/28.421 ms, pipe 3

If you do this a few times a day, over several days, and your avg is under 130ms and you have 0% packet loss, you're ready for [[VoIP]]. If not, call your internet service provider (ISP) and ask them to resolve the issue.
