Help capturing VOIP audio?


Hello everyone,

I am trying to create an audio installation for an art show next season which requires live sampling of phone conversations from willing participants. I have turned to Wireshark as a means of recording these calls wirelessly. So far, I have tried to use the “VoIP Calls” feature under the Telephony menu to capture conversations and record them, but the calls i’m making are not being picked up by Wireshark.

Here is my setup: 2 smartphones (both Android) both connected to the same home internet service (Verizon FiOS). My computer is also connected to the same home wifi signal, but when I start capturing packets on this wifi signal I am NOT able to detect the VoIP call being made on these smartphones (using the smartphone app Viber).

Can anyone tell me what I’m doing wrong? Maybe suggest a better method of capturing VoIP calls on my laptop? Also, if there is a way to save these conversations to a folder on my computer AUTOMATICALLY it would save a lot of coding.

Any help would be GREATLY appreciated!

Thank you so much for your time,
