ENA Amplifier Configuration (SIP)

ENA Amplifiers in SIP mode

This article describes the configuration settings available for the ENA IP Network Amplifier in SIP mode. The ENA Amplifiers are configured through their web interface.

Functions available in advanced configuration mode can be found here.

Software requirements

Minimum Software requirement

• ENA Amplifier: 5.1.3.0

Main

Information

• Log In to the amplifier
• The Information page will now be displayed, showing the amplifier configuration and status.

The Information page

To find the IP address of the amplifier, use the Intercom Management Tool, IMT. On older ENA amplifiers with a front display use the Menu Selection Knob, and navigate to Information > Network.

Main Settings

• Click Station Main > Main Settings to access the page for configuring Station Mode and IP parameters.

The Main Settings page

Station Mode: Select the SIP radio-button.

Preferred Internet Protocol: Select either IPV4 or IPV6.

IP Settings:

• DHCP – Select this option if the IP station shall receive IP Settings from a DHCP server.
• Static IP – Select this option if the IP station shall use a static IP address. Enter values for:

- IP-address

- Subnet-mask

- Gateway

- DNS Server 1 (option for network administration)

- DNS Server 2 (option for network administration)

- Hostname (option for network administration)

• Disable Reset to Factory default settings using frontboard and I/O: If enabled, factory reset will only be possible from the web interface. This is disabled by default.

• Enable RSTP: RSTP is only required when using redundant networking

Click Save followed by Apply to apply the new configuration settings.

Recovery

Commands

The Recovery page

• Full reboot: Perform a full Linux reboot. No configuration is lost
• Partial reboot: Perform a restart of the intercom application. No configuration is lost
• Factory reset: Set all parameters to Factory Default values. The amplifier will get static IP Address 169.254.1.100.
• Factory reset with DHCP: Set all parameters to Factory Default values. The amplifier will get IP Address from DHCP server. If no DHCP server in the network, it will get a random 169.254.x.x IP address.

SIP Configuration

Account/Call

Select SIP Account -> Account/Call to access the page for configuring the SIP Account Settings.

The Account/Call Settings page

Amplifier Settings

• Name: Enter a name for the amplifier.

Channel 1/2 Account Settings

• Name: Enter a name that will be shown on the display at the remote party.
• Number (SIP ID): This is the identification of the station in the SIP domain, i.e. the phone number for the station. This parameter is mandatory. Enter the SIP ID in integers according to the SIP account on the SIP domain server.
• Server Domain (SIP): The IP address of the SIP Server. This can be either an IP address in regular dot notation or a hostname.
• Backup Domain (SIP): This is the secondary (or fallback) domain. If the station loses connection to the primary SIP domain, it will switch over to the secondary one. This can be either an IP address in regular dot notation or hostname.

• Authentication Password: The authentication user password used to register the station to the SIP server. This is required only if the SIP server requires authentication
• Register Interval: This parameter specifies how often the station will register, and reregister in the SIP domain. This parameter will affect the time it takes to detect that a connection to a SIP domain is lost. Enter the values in number of seconds from 60 to 999999. The default interval is 600 seconds.
• Outbound Proxy [optional]: Enter the IP address of the outbound proxy server in regular dot notation, e.g. 10.5.2.100, or as a hostname.

  • Measure (60 second timeout, only available if Monitor Mode is Manual and channel is successfully calibrated) will manual monitor channel for 60 seconds and report any faults detected

IO Monitoring

The ENA amplifier offers monitoring of the outputs and the inputs:

• RCOs

RCO is not supported for ENA amplifiers in SIP.

• RCIs
  • RCI Config allows configuring the thresholds for when the RCI triggers. An RCI has an open voltage of 10V across the terminals. A resistor network is needed to ensure that RCI's can be monitored properly.
  • Monitor RCI enables monitoring of RCI.
  • Not Connected - When the voltage on the pin is higher than this threshold, it's set as Not Connected.
  • Not Pressed - Low threshold for the RCI to be considered not pressed.
  • Pressed - High threshold for the RCI to be considered pressed.
