The following fields are displayed:

Filter

Parameter

Description

Name

Specify the user name of this signaling trace filter.

Peer IP Address

Specify the Peer IP Address for signaling tracing

Peer IP
Address Prefix

Specify the IP subnet prefix of this peer IP address.

Local IP Address

Specify the local IP Address for signaling tracing.

Local Port
Number

Specify the UDP/TCP port number of the call trace signaling filter.


Note

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.
