# Check PCAP

Class 4 let's you search for PCAP simply.  To do so, you first go to Tools > SIP Packet Search:

![](/files/-MYX-GfWRHfivqkbEphz)

Then, you can see the search page with all the filter fields:

![](/files/-MYX-RO6435Lc_r8DsJk)

After you submit, you can see all the CDRs that match your search criteria:

![](/files/-MYX-jSpFwUhWGG4T0Or)

You can click "SIP" next to Origination Call ID to see the ingress side of PCAP and you can click on Termination Call ID to see the ingress side of the PCAP. 

You can click "Full" to see the full ingress + egress PCAPs for a specific incoming call.  

It will take a short time to retrieve the PCAP file and it will be available in the "SIP Requests" tag:

![](/files/-MYX08Z-gH4Ppsgq8tgz)
