"Latency" directs Telnyx to route media through the site with the lowest round-trip time to the user's connection. Telnyx calculates this time using ICMP ping messages. This can be disabled by specifying a site to handle all media.

You will need to input a URL where all the webhook events will be sent. Also, you can setup a fail-over URL. If two consecutive delivery attempts to the primary URL fail, Telnyx will attempt delivery to this URL. NOTE: Must include a scheme such as 'https'.

Determines which webhook format will be used based on the API version V1 or V2.

We recommend using API V2, as it contains a richer feature set versus the initial version which will be deprecated in the future.

When enabled, you will specify the number of seconds Telnyx will wait for commands from your application before hanging up.

In this field, you will need to specify a delay in seconds for Telnyx to wait before retrying an unsuccessful webhook delivery attempt. If not set, Telnyx will retry immediately.

There are three types in this field: RFC 2833, Inband and SIP INFO.

You can configure your global application settings for outbound calls over here.

Assign your application to an outbound voice profile in order to make outbound calls.

You can limit the total number of outbound calls to phone numbers associated with this connection.
