Spokes is a runtime engine and software stack to facilitate interaction with and management of Plantronics devices including headsets, handsets and speakerphones.

Editorial Note

This article is in the Product Showcase section for our sponsors at CodeProject. These reviews are intended to provide you with information on products and services that we consider useful and of value to developers.

 

Overview

Spokes is a runtime engine and software stack to facilitate interaction with and management of Plantronics devices including headsets, handsets and speakerphones.

3rd party applications can interact with Plantronics devices using Spokes via the 3 different APIs: COM Service, REST Service and iPlugin SDK.

These 3 API options are shown in the below diagram:

What are the key features of the Plantronics device platform that applications can leverage using Spokes?

  • Wearing Sensor

    • Get initial wearing state, receive events when it changes
  • Proximity

    • Register for proximity, receive updates of user’s range to PC
  • Headset docked state

    • Notified when device is docked/undocked
  • Mobile caller id / call management

    • Caller id of incoming / outgoing mobile calls
    • Dial / answer / reject / end mobile calls via Spokes API
  • Serial number

    • Programmable unique id per device
    • Uses for asset tracking or application user personalisation
  • Data Logging

    • Log information about device usage as well as any information important to your application from other services, cloud applications etc.
  • Call control

    • Softphones can notify Spokes of inbound/outbound calls via high-level API
    • No need to perform low-level device control
    • Note: also be informed of on-going call progress in other softphone apps supported by Plantronics (see list below) – multi softphone support
  • Multi-line support

    • Receive events to notify the calling status / held status of the 3 lines (PC, mobile and desk phone)

Note: the set of above features available will vary depending on the Plantronics device in use.

There are 3 APIs - which one do I use with my application?

Languages supported today with current Spokes SDK:

 

iPlugin SDK

COM Service

REST Service

C#

Yes

Yes*

No

C++

No

Yes

No

JavaScript

No

No

Yes

*Note: The C# support for COM Service requires integrations to target .NET Framework 4.0 or higher only.

COM Service API with C#: How do I get started?

The COM Service allows your application to remain nicely decoupled from the Plantronics Spokes runtime. Integrating to C# is facilitated through adding an interop assembly to your project.

  • This is described in a quick start tutorial for Blackwire 700 device (will also work with other devices): click here.
  • There is a more comprehensive command-line demo (screenshot below) showing more API features: click here.
  • For more samples check out the DevZone

COM Service for C++: How do I get started?

  • There is a comprehensive command-line demo similar to above that shows the API features: click here.
  • For more samples check out the DevZone

REST Service API with JavaScript: How do I get started?

  • There is a hello world tutorial: click here.
  • There is a more comprehensive sample showing more of the API: click here
  • There are also some great blog posts around the JavaScript features.
  • For more samples check out the DevZone

iPlugin API for C#: I’ve written my own plugin, how do I load it into Spokes?

  • You copy your plugin DLL to the folder of “PlantronicURE.exe” (the Plantronics runtime)
  • Then you add an entry to the PURE.xml file to tell it to load your plugin
  • Then arrange for PlantronicsURE.exe to restart.
  • For some sample code of iPlugins for Spokes, refer to the C# section of DevZone.

Where is the PURE.xml file?

It can be in 2 places:

  • C:\ProgramData\Plantronics\PlantronicsURE\PURE.xml
  • %localappdata%\VirtualStore\PURE.xml (Sometimes Spokes is using a "virtual" copy of the file in here)

Example entry for PURE.xml

<Plugin Name="MyPlugin" ProcessName="" Enabled="true" Active="false">
  <Assembly>MyPlugin.dll</Assembly>

What do those tags mean?

  • <Plugin> - defines the name of the Plugin, and also the Enabled and Active flags which get updates in realtime as the plugin initializes (refer to the samples).
  • <Assembly> - defines the DLL name of the Plugin
  • <ClassType> - can optionally define the type name of the iPlugin-derived class within the Plugin DLL that the runtime should instantiate
  • <Type> - defines the type of plugin this is from this list:
public enum PluginType
{
     Unknown = 0,
     SoftPhone= 1,
     MediaPlayer = 2,
     Application = 3,
     Service =4
}
  • <FeatureType> - defines additional features the softphone may have from:
public enum PluginFeatureType
{
     None = 0x0,
     MakeCall = 0x1, --> is able to handle MakeCall (dialling) event from device
     EscalateIMToVoice = 0x2 --> not used
}
  • <CustomProperty> - defines a custom property value for use in your plugin. You can obtain the value of this property in your plugin code using the following code:
    String m_myProperty = m_sessionMgr.GetCustomProperty("MyPlugin", "MyProperty");

    Where MyPlugin is the Plugin name give in the Plugin tag above, and MyProperty is the key of the CustomProperty. Note: can also set the value with SetCustomProperty method, so the property in PURE.xml can be used as small persistant store, e.g. for screen coordinates, file names, etc.
