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 emailssent by the systemIVR language: Must be

added manually

3

System Settings—Appearance

Session timeout: Automatically logs you out of web session

CDR URL: Where to send CDRsRecordings: 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: Formulti-domain environments

f = shortfrom = 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 (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.

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.
