General Network Checklist

Checklist

The following checklist is applicable to most customers using the Tango Tango service with their own Android, iOS, or Desktop/Laptop devices. Following this checklist can help ensure the best user experience possible when using the Tango Tango service.

• Devices can access internet hosts using HTTPS and websocket protocols on TCP port 443.

• iOS devices must be able to connect to APNS and receive push notifications. (More Info)

• Android devices must be able to connect to FCM and receive push notifications. (More Info)

• Android devices which do not have the Google Play store must be able to receive push notifications from the Pushy push notification service (More Info).

• Devices can perform perform a GET request against our health check API (details below). This response should be received within 1 second.

• Devices must be able to join calls within 3 seconds - though they should join in less that 1 second for a good user experience. This latency can be observed by reviewing call detail records in the admin portal, or by contacting Tango Tango support for a report.

• When on WiFi, devices must be able to maintain a connection (via websocket) to the PTT service without reconnecting or dropping packets when roaming between access points.

• When on WiFi, configuration should be applied to drop devices that attempt to connect with a low signal level that won’t allow the device to meet these requirements.

Performing a Service Health Check

You can check connectivity to the Tango Tango PTT service by performing an HTTPS GET request against the /darmok endpoint. It should reply with a 200 OK response and the text jalad.

The following curl command will perform this request and report how long it takes - but any HTTPS client or health checking tool should be able to perform this test.

curl -o /dev/null -s \
	-w 'Total: %{time_total}s\n' \
	https://manage.tangotango.io/darmok

Required Internet Hosts

The following information is for networks which perform outbound connection filtering. In all of the following cases, devices initiate the connection to the given host. The Tango Tango service never initiates a connection from our services or the services we use. No port forwarding is required.

Additional Items for Tango Tango Managed Devices

These requirements only apply to devices sold and managed by Tango Tango, such as a Siyata SD7, that was purchased as part of a managed service agreement.
