| Info |

| When you enable Signaling Packet Capture without any configuring any signaling filter (the default behavior), the SBC creates a default filter using all the configured signaling IP addresses and ports. The default filter collects only the first fragmented IP packet and ignores the rest. This happens because the UDP/TCP ports are also included in the default filter, but the IP packet fragments except the first fragment does not include the relevant headers. For the same reason, even if you create a filter which includes only the Local Port Number, the fragments except the first one are not captured. To capture all packet fragments, create a Signaling Packet Capture filter with specific Local IP Address, or Peer IP Address, or both, and then enable Signaling Packet Capture. |
