Turbine stations supports the following codecs: G.711a, G.711u, G.722, G.729

Create a User for the Turbine Station

A user must be configured for all Turbine Station Extensions.

• From the Configuration tree right-click User and select New

When the User window opens, select the User tab and enter the following:

• Name
  • Enter a name for this user, e.g. Intercom
• Password
  • Enter the Password (not mandatory)
• Confirm Password
  • Enter the Password again (not mandatory)
• Extension
  • Enter the extension number that was created previously in section "Create a SIP Extension for the Turbine station"

• Select the Telephony tab
• Select the Supervisor Settings tab

• Click the OK button to save the settings

Login Code value is used as SIP Authorization Password on the Turbine station

Save Configuration

Once the configuration data is complete, it must be sent to the IP Office.

• Click the Save icon as shown below

• Once the Save Configuration window opens, click the OK button

Configure Turbine station

The following steps detail the configuration for the Turbine station using the Web Interface of the station. The steps include the following areas:

• Launch Web Interface
• Add Root Certificate
• Administer SIP Settings
• Configure Direct Access Key

Launch Web Interface

To access the Turbine station web interface:

• Enter http://<ipaddress> in an Internet browser where <ipaddress> is the IP address of the Turbine station
• Log in with the appropriate credentials (default username: admin, password: alphaadmin)

The IP-StationWeb screen displays the Station Information.

Administer Main Settings

Under the Station Main tab:

• Select Main Settings
• Under Model select :
  • For TCIS stations select:
    • Kit (TKIS-2SIP)
    • Normal (TCIS-1SIP, TCIS-2SIP, TCIS-3SIP)
    • OLED Labels (TCIS-4SIP, TCIS-5SIP)
    • Scrolling Station (TCIS-6SIP)

    • Video Scrolling Station (TCIV-6SIP)
  • For TMIS stations select:
    • TMIS1-SIP
• Click Save when done
• When a screen appears (not shown) to confirm the setting, click Apply

The Turbine station will now reboot.

Administer SIP Settings

Under the SIP Configuration tab:

• Select SIP Settings to configure the parameters in the Account Settings section
• Set the Turbine stations support UDP, TCP and TLS configuration options
• For TCP and TLS options, it is necessary to set Outbound Proxy to have the same value as Server Domain

Avaya servers may need to enable the option for Use Unencrypted SRTCP

Add certificate on Turbine station

Using SIP TLS requires you to upload a certificate to be able to do encrypted authentication and communication.

This step must be done before the station is able to register to the PBX.

• Select SIP Configuration tab and from the left hand menu
• select Certificates.

The Turbine certificates are listed.

• Click on Choose file and browse to the location of the root certificate .pem file.
• When selected click on the Upload button

The root certificate is uploaded and is shown in the list (default.pem).

• Reboot Turbine station ( Station Administration → Reboot → Reboot )

Uploading a certificate is only needed when using SIP TLS

Avaya IP Office Configuration

• Open the Avaya IP Office Manager tool
• Select System > LAN1 > VoIP
• Check the TLS box (Default TLS port: 5061, Remote TLS Port: 5061)

Option 1: Enable SRTP at System Level

Secure Real-Time Transport Protocol (SRTP) refers to the application of additional encryption and or authentication to VoIP calls (SIP and H.323). SRTP can be applied between telephones, between ends of an IP trunk or in various other combinations.

To configure SRTP at the system level:

• Select System > VoIP Security
• Under Media select Preferred

When enabling SRTP on the system, the recommended setting is Best Effort (Preferred).

In this scenario, IP Office uses SRTP if supported by the other end, and otherwise uses RTP.

If the Enforced setting is used, and SRTP is not supported by the other end, the call is not established.

Option 2: Enable SRTP Per Extension

• Select Extension > ext # > VoIP
• Disable option Same As System and configure parameters

• Save configuration

Upload Certificate to Avaya IPO

In Avaya IP Office Manager:

• Select File > Advanced > Security Settings
• Select Security > System > Certificates
• Enable option Use different Identity Certificate for Telephony

Avaya makes incoming TLS connections, and in that case it is necessary to have a private key.

To upload Private Key and Certificate:

• Under Telephony Certificate click Set
• Select Paste from clipboard option

In our example, we are using the default.pem certificate and default.key private key.

Private Key


Certificate

• Change option Received Certificate Checks from None to Low (or higher)

• Click Add to add default.pem to Trusted Certificate Store (choose between Import certificate from file or Paste from clipboard)
• Click OK and Save configuration

Configure Direct Access Keys

In the web interface of the Turbine station select SIP Configuration tab:

• Select Direct Access Key Settings > DAK 1 to configure it
• In the Idle field select Call To from the dropdown and enter the extension number to be called when the DAK 1 key is pressed
• In the Call field select Answer/End Call and On Key Press

Backup Domain Configuration

This section provides configuration procedures for configuring redundacy, backup, and server for the Turbine station.

Select SIP Configuration > SIP Settings to configure the following in the Account Settings section

All configuration is the same as in section "Administer SIP Settings" with additional fields for configuration Backup and Backup 2 servers:

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.

Backup Domain 2 (SIP): This is the tertiary SIP domain used as backup in case the primary and secondary domains fail. This can be either an IP address in regular dot notation or hostname.

Outbound Backup Proxy (mandatory for TCP and TLS, optional for UDP transport protocol): Enter the IP address of Session Manager and 5060 (5061) as the Port for UDP/TCP (TLS)

Outbound Backup Proxy 2 (mandatory for TCP and TLS, optional for UDP transport protocol): Enter the IP address of Session Manager and 5060 (5061) as the Port for UDP/TCP (TLS)

Select Registration Method from the dropdown:

• Parallel
  • In Parallel mode the IP station will try to be registered to all configured SIP servers at the same time. The station will use the primary SIP server for outgoing calls if available, otherwise it will use the next available backup server. In this mode, the station can receive calls from multiple SIP servers at the same time. This mode is not recommended in a Cisco Unified CallManager cluster with multiple publishers and subscribers.
• Serial
  • Serial registration means that the station will always register to the next available SIP server. The station starts by registering to the primary SIP server, then if the station loses contact with the primary SIP server it will register to the backup server. If the station loses contact with the backup server, then it will register to the secondary backup server. If the station loses contact with the secondary backup server, it will register to the primary SIP server.
• Top-Down
  • Top-Down registration means that the station will try to be registered to the primary SIP server, but periodically poll the backup servers to check that they are up without registering. If the primary SIP server shuts down, then the station will register to the next backup server that is up. If the primary SIP server starts up, the station will unregister at the backup server and switch back to the primary server.
• Cisco
  • Cisco registration is the same as Top-Down for the primary and backup servers, while the secondary backup server will register to its configured server in parallell.

Verification steps

This section provides the tests that can be performed to verify the correct configuration of Session Manager and the Turbine station.

Verify Avaya IP Office SIP Endpoint Registration

• Open the IP Office System Status application and click Extensions
• Verify that Turbine endpoints are successfully registered as shown below

Verify Turbine Station SIP Registration

In the Turbine station web interface:

• Select Station Main > Station Information
• Verify that the status shows Registered under Server Domain (SIP)

Place a call to another endpoint to verify basic call operation.

Verify Successful Calls

Place a call to and from the Turbine station endpoint. Verify that 2-way audio can be heard and validate that the call terminates successfully.
