hi, just to ask what tools that i can use to mesure factor that affect voice in VoIP Network, such as
- packet loss
thank for your reply
extended ping is one off the tools
also u can use "sh call active vo br" or " sh call his vo br" to see the drops / jitter as well as the early packets
these is on production n/w
thank for your reply, if i use extended ping, do i need to add -l to set size of ping packet = to size of voice packet?
because test is for voice,not for all traffic. since size of voice packet is fixe , i thing codec G711 (64k) +IP header , i can set approximatively size to 128k.
i use ping because i will these test directly between end PCs with IP Softphone installed
yes u can use it , but basically i use this for jitter and drops with tos byte ( for correct qos)
if u want more detail u can also use the SLA with jitter( their is voice under this object, but we still use jitter, see cisco doc)
You can use IPERF. It`s a free DOS based application that works in a client-server manner. You can personalize the traffic with the Cisco Voice options.
