Re: [Wireshark-users] Monitoring traffic from a VOIP phone
Hi Tim, If I understand you correctly, your setup is like: PC -- VoIP phone -- router -- modem -- internet where the VoIP phone contains an integrated two-port Ethernet switch. One way would be to extend your setup with a hub, like: PC -- VoIP phone -- router -- hub -- modem -- internet Make sure the hub is an authentic hub, forwarding all packets to all ports. Avoid a switch. Connect 3 ports to this hub: - the WAN Ethernet port of the router - the Ethernet port of the modem - the LAN Ethernet port of a PC (running Wireshark) Wireshark should sniff all traffic between your LAN and the Internet, so you might want to filter on IP address(es) or VoIP protocol (e.g. sip). Happy sniffing, Tom.

I've had a look around and was wondering if anyone could point me in the right direction. I connect to a router through the phone and the phone connects directly to the router (a Belkin N1), is there anyway I can monitor the traffic to/from the VOIP provider?

Thanks Tom, I've only got a switching hub here but will pop out and pickup a standard hub. I'll let you know how I get on.

Re: [Wireshark-users] Monitoring traffic from a VOIP phone
You will probably not be able to buy a new true hub. Most if not all currently manufactured devices are switches. E-bay is a good source of hubs.
