  1. System Settings • When this module is complete, you will be able to: • Navigate the admin-level web interface pages • Set a new name for your system • Customize port settings (configure the timing port and add an HTTP port) • Add phones to the Access List

  2. System Settings—General Page System name: Used in emails sent by the system IVR language: Must be added manually

  3. System Settings—Appearance Session timeout: Automatically logs you out of web session Weak passwords are biggest vulnerability to any VoIP deployment. CDR URL: Where to send CDRs Recordings: Specify file location

  4. General Settings—Performance Max number calls: If blank, the system key or CPU will limit the calls. Process affinity mask: Tells the system which core to bind to. Max. size config. backup file: Back up system from the OS when possible (this setting was meant for the appliance). Max. number of registrations: Set per extension.

  5. General Settings—SIP Settings sip.mcast.net: The PBX listens on this multicast address for requests from phones looking for the PBX during PnP (in SIP RFC 3261). f = short from = long * Indicates that a restart is necessary Loopback detection: Formulti-domain environments Remote SIP management: Used for large deployment of snom ONE servers to automatically update them via SIP NOTIFY.

  6. Ports―HTTP and SIP Supports HTTP and HTTPS Supports multiple transport layers IP Routing List: Used when you don’t have two NICs in the machine SIP Replacement List: Used when PBX is on a private address and remote phones must connect

  7. Ports―RTP Some UAs can send/receive RTP on different ports. Don’t change the negotiated codec with a re-invite. Specify the multicast address to use. Bind the system to only one NIC.

  8. Ports―SNMP, TFTP, LDAP SNMP support: Used for polling statistics. TFTP: For firmware updates and to send down phone’s configuration files automatically and via PnP. LDAP: For address book

  9. SNMP―Keep an Eye on the System SNMP serves different purposes Performance measurements Alerts when system is down (Email/SMS) Standard tools can be used Trusted addresses Limit the access to sensitive information List of allowed addresses (with or without net mask) Available information: Call Objects, Registrations, Messages: Resource Usage Call Attempts, Calls: BHCA, BHCC http://www.paessler.com/prtg - Free version allows you to monitor up to three sensors.

  10. System Settings―Configuration • Click here to save the system on a remote location for restoral (pbx.tar). • Note: Clean out recording directory if it is very large. • Import your XML-based configuration file. • Reload configuration files without restarting.

  11. System Settings―Configuration Upload customized configuration files for use during PnP. Reboots the entire computer

  12. Music on Hold Sources • File • Endless music sample (default is 20 sec.) • 8 kHz, 16 bit/sample file • Keep files short • Windows version supports input from the audio input: • External CD player, radio, external MP3 player, etc. • RTP stream: • ulaw encoded (CPU) preferred, but supports all codecs • Port must be provisioned during setup

  13. Access Lists Allow or disallow remote devices to connect to the system.

  14. Web Page Control Requires HTML knowledge to edit the templates Templates

  15. Web Page Control Translation

  16. Web Page Control If Show is set to No, the associated settings will not be visible to the user:

  17. Administrator Status Screen

  18. Status Tab—Graphs 24-hour CPU chart

  19. Status Tab—Logfile • Contains full SIP traces and other events • Easy to filter • Can be saved to file • Date and time • Type of packet • Rx = received • Tx = transmitted • Tr = transmitted the same response again • Transport type • IP address and port the packet was received or sent to Log event is in brackets [ ]

  20. Status Tab—Logging Log length: Determines how long the log stays in the web. Log Level: 0 = lowest 9 = highest (chatty) Default = 5 Turn on only when troubleshooting. Log level 7 gives full SIP packets. Very granular Can log just about every event easily.

  21. Status Tab—Logging (cont’d) Other messages are SIP INVITE. Log watch list: Filters out unwanted devices.

  22. Status―CallLog Length can be customized (be careful not to set too large!) Shows complete list of calls

  23. Status Tab―Calls Delete hanging or active calls. Active calls “alerting” = a ringing call

  24. Lab: Set Your System Name See Exercise 19 in your lab book for complete exercise.

  25. Lab: Change the HTTP Port See Exercise 20in your lab book for complete exercise.

  26. Lab: Set the NTP Timing Port snom ONE • pool.ntp.org: • Default time server for networked appliances • Huge virtual cluster of time servers • Provides reliable NTP service for tens of millions of systems around the world. Phone GUI (Advanced settings) See Exercise 21 in your lab book for complete exercise.

  27. Lab: Add Phones to Access List Add your phones to the access list. See Exercise 22 in your lab book for complete exercise.

  28. Lab: Customize User Settings From the Web Page Control tab, click UserPage Control. Disable a few of the settings. Log out. Log back in as a user to verify that these settings are no longer visible to the user. See Exercise 23 in your lab book for complete exercise.
