which sysinternal tool can check which process is sending SIP and RTP traffic to which server

Hi ,

My company uses a web based softphone to receive or make calls to customers. but that softphone system is provided by a third party.
Now I want to figure out, our web based softphone will connect to which server , I need to know the FQDN or IP address of server, in order to route those voice traffic to a dedicated link.

I tried to find that by using tcpview64 , but it can't show me voice traffic , which is SIP/RTP protocol , just like its' name suggest, tcpview64 just support TCP and UDP.

Any one knows , which Sysinternal tool can be used to achieve my purpose ? sysmon ?

Why must it be a sysinternals tool?

thanks , it does can capture SIP/RTP traffic, but I also want to know softphone client is connect to which server ,you may say , I can see server IP in Wireshark , that's true ,but I want to know the FQDN of server , it's clear in tcpview tool , as long as you don't enable "Resolve Addresses" function under i"Option" menu. And of course , some client my connect to server with IP directly , but I think most of them will use FQDN instead. I need to use FQDN to make policy based routing to route traffic to a dedicated link.
