VoIPmonitor: Filter and View Registration Logs

• Click on SIP Register.

• The SIP Register section has three tables - Active registered SIP users, Failed registrations, and State changes in SIP registrations.

1. 1
   Active Table: shows current registered users
2. 2
   Failed Table: If some device fails to register continuously the counter column increases instead of creating a new row. If there is a one-hour gap between two failed registrations from the same user a new row will be created.
3. 3
   State Table: In each state row you can click on detail [+] to show all related SIP register messages to the selected user. If the device registers in regular intervals it will not save state change in the state table but keeps the last registration status until the re-registration stops - then UNREGISTER will be the last register state change. If the device does not resend registration in time (register expires + 5 seconds) the last state will be EXPIRE (with red flag).

• The fields for each table are the following:
  • ID/sensor id shows internal unique ID and if enabled sensor id
  • datetime is time creation
  • User name / realm shows username and realm from REGISTER message
  • Source IP / Destination IP
  • From / To / Contact are values from SIP headers
  • Expires at shows date when the registration expires
  • User-agent - Phone Model
  • Commands - download PCAP
