I don't know if this should be in the Avaya forum or here but since it's about network statistics I'll start here. We have an Avaya phone system at work and issue out IP phones to remote employees at home. They connect this phone to a switch or port on their router and the phone has their login credentials to register to a VPN concentrator here at work to which is connected to its own internet pipe. (voice only traffic) A user complains about calls being dropped and from what he describes, packet loss. It has to be either the phone (which I've sent replacements) or his ISP. He says it's not his ISP since his PC has no issues and he gets 10Mb upstream/downstream, fiber to his house, bla bla bla, but with voice being much more sensitive I'm still not convinced.
Would he be able to download, say Wireshark, and capture the data to see if there is significant packet loss of jitter? His phone would have an IP address the company VPN concentrator gave him so I don't know how he would capture the traffic going to the phone. Unless he maybe filters it to capture only UDP traffic and does nothing on his PC. I've never used Wireshark at home so I don't know if it's valuable for home traffic studies or not. I'm also not much of a network guy so any help would be appreciated. Especially if you can tell me how I can prove it's his ISP and not the device. Thanks.
