Use the SIP Sig Port TLS Statistics window to view TLS connection statistics for SIP signaling ports.
On the SBC main screen, go to Monitoring > Zone > Signaling Ports > SIP Sig Port Tls Statistics or
Monitoring > Zone > Zone Specific > SIP Sig Port Tls Statistics
The SIP Sig Port TLS Statistics window opens showing TLS connection statistics for all SIP signaling ports. Use the Address Context and Zone lists to filter the output based on address context and zone.
SIP Sig Port TLS Statistics Window (Partial)
The output includes the following parameters:
SIP Sig Port TLS Statistics Parameters

| Current Server Handshakes | Number of incomplete server handshakes. |
| Session Resumptions | Number of server sessions that have been resumed. |
| No Cipher Suite | Number of handshake failures due to inability to converge on a cipher suite. |
| Handshake Timeouts | Number of handshakes that timed out before completing. |
| Higher Auth Timeout | Number of handshakes in which the SBC was the server and the client did not authenticate itself through TLS and failed to authenticate itself through any higher level protocol. |
| Client Auth Failures | Number of times a peer failed TLS authentication with the SBC as the client. |
| Server Auth Failures | Number of times a peer failed TLS authentication with the SBC as the server. |

| Handshake Failures | Cumulative total of all handshake failures. |
| Receive Failures | Number of receive failures (failure to decrypt). |
| Send Failures | Number of send failures (failure to encrypt). |
| No Auth Drops | Number of SIP messages dropped due to lack of peer authentication at the SIP level. |
| No Auth488 | Number of SIP messages rejected with a 488 response due to lack of peer authentication at the SIP level. |
| Mid Connection Hello | Number times a peer sent a TLS Hello on a connection that was already up. |
| No Client Cert | Number times the SBC was the client and failed to derive a certificate to send the server. |
| Validation Failures | Number of failed certificate validations. |
