RingCentral.Net.Pubnub

PubNub Extension

Install this extension if you want to use PubNub and your app targets traditional .NET framework.

Check RingCentral.Net.PubnubPCL if your app targets .NET Core, Mono, Xamarin...etc.

var rc = new RestClient(
    Environment.GetEnvironmentVariable("RINGCENTRAL_CLIENT_ID"),
    Environment.GetEnvironmentVariable("RINGCENTRAL_CLIENT_SECRET"),
    Environment.GetEnvironmentVariable("RINGCENTRAL_SERVER_URL")
);
var pubNubExtension = new PubNubExtension();
await rc.InstallExtension(pubNubExtension);

var eventFilters = new[]
{
    "/restapi/v1.0/account/~/extension/~/presence?detailedTelephonyState=true",
    "/restapi/v1.0/account/~/extension/~/message-store"
};
var subscription = await pubNubExtension.Subscribe(eventFilters, message =>
{
    // do something with message
});

PubNub notification delay issue

If you create multiple subscriptions in a single app and run the app in .NET Framework environment, you may experience notifications delay. Delay time is around 4 minutes and 30 seconds.

A solution/workaround is to add the following to your app.config file:

<system.net>
<connectionManagement>
<add address = "*" maxconnection = "999" />
</connectionManagement>
</system.net>

Notes:

• If you run your app in .NET Core environment, you will not have this issue.
• If you only create one subscription in your code, you will not have this issue either.
• This is because by default only 2 connections to a server is allowed.
