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 s sent by the system IVR language: Must be added manually

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

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. number of registrations: Set per extension. Max. size config. backup file: Back up system from the OS when possible (this setting was meant for the appliance).

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

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

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

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

9 SNMP ― Keep an Eye on the System  SNMP serves different purposes –Performance measurements –Alerts when system is down ( /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  - 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. Reload configuration files without restarting. Import your XML-based configuration file.

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

12 Music on Hold Sources  RTP stream: –ulaw encoded (CPU) preferred, but supports all codecs –Port must be provisioned during setup  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.

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

14 Web Page Control Templates 14 Requires HTML knowledge to edit the 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 Log event is in brackets [ ]  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  Contains full SIP traces and other events  Easy to filter  Can be saved to file

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

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

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

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

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

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

26 Lab: Set the NTP Timing Port See Exercise 21 in your lab book for complete exercise. 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. snom ONE Phone GUI (Advanced settings)

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 1.From the Web Page Control tab, click UserPage Control. 2.Disable a few of the settings. 3.Log out. 4.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.
