Telnyx Voice Gather - Java

Installation

// See https://github.com/team-telnyx/telnyx-java for Maven/Gradle setup

Setup

import com.telnyx.sdk.client.TelnyxClient;
import com.telnyx.sdk.client.okhttp.TelnyxOkHttpClient;

TelnyxClient client = TelnyxOkHttpClient.fromEnv();

All examples below assume client is already initialized as shown above.

Add messages to AI Assistant

Add messages to the conversation started by an AI assistant on the call.

POST /calls/{call_control_id}/actions/ai_assistant_add_messages

import com.telnyx.sdk.models.calls.actions.ActionAddAiAssistantMessagesParams;
import com.telnyx.sdk.models.calls.actions.ActionAddAiAssistantMessagesResponse;

ActionAddAiAssistantMessagesResponse response = client.calls().actions().addAiAssistantMessages("call_control_id");

Start AI Assistant

Start an AI assistant on the call.

POST /calls/{call_control_id}/actions/ai_assistant_start

import com.telnyx.sdk.models.calls.actions.ActionStartAiAssistantParams;
import com.telnyx.sdk.models.calls.actions.ActionStartAiAssistantResponse;

ActionStartAiAssistantResponse response = client.calls().actions().startAiAssistant("call_control_id");

Stop AI Assistant

Stop an AI assistant on the call.

POST /calls/{call_control_id}/actions/ai_assistant_stop

import com.telnyx.sdk.models.calls.actions.ActionStopAiAssistantParams;
import com.telnyx.sdk.models.calls.actions.ActionStopAiAssistantResponse;

ActionStopAiAssistantResponse response = client.calls().actions().stopAiAssistant("call_control_id");

Gather stop

Stop current gather.

POST /calls/{call_control_id}/actions/gather_stop

import com.telnyx.sdk.models.calls.actions.ActionStopGatherParams;
import com.telnyx.sdk.models.calls.actions.ActionStopGatherResponse;

ActionStopGatherResponse response = client.calls().actions().stopGather("call_control_id");

Gather using AI

Gather parameters defined in the request payload using a voice assistant.

POST /calls/{call_control_id}/actions/gather_using_ai — Required: parameters

import com.telnyx.sdk.core.JsonValue;
import com.telnyx.sdk.models.calls.actions.ActionGatherUsingAiParams;
import com.telnyx.sdk.models.calls.actions.ActionGatherUsingAiResponse;

ActionGatherUsingAiParams params = ActionGatherUsingAiParams.builder()
    .callControlId("call_control_id")
    .parameters(ActionGatherUsingAiParams.Parameters.builder()
        .putAdditionalProperty("properties", JsonValue.from("bar"))
        .putAdditionalProperty("required", JsonValue.from("bar"))
        .putAdditionalProperty("type", JsonValue.from("bar"))
        .build())
    .build();
ActionGatherUsingAiResponse response = client.calls().actions().gatherUsingAi(params);

Gather using audio

Play an audio file on the call until the required DTMF signals are gathered to build interactive menus.

POST /calls/{call_control_id}/actions/gather_using_audio

import com.telnyx.sdk.models.calls.actions.ActionGatherUsingAudioParams;
import com.telnyx.sdk.models.calls.actions.ActionGatherUsingAudioResponse;

ActionGatherUsingAudioResponse response = client.calls().actions().gatherUsingAudio("call_control_id");

Gather using speak

Convert text to speech and play it on the call until the required DTMF signals are gathered to build interactive menus.

POST /calls/{call_control_id}/actions/gather_using_speak — Required: voice, payload

import com.telnyx.sdk.models.calls.actions.ActionGatherUsingSpeakParams;
import com.telnyx.sdk.models.calls.actions.ActionGatherUsingSpeakResponse;

ActionGatherUsingSpeakParams params = ActionGatherUsingSpeakParams.builder()
    .callControlId("call_control_id")
    .payload("say this on call")
    .voice("male")
    .build();
ActionGatherUsingSpeakResponse response = client.calls().actions().gatherUsingSpeak(params);

Gather

Gather DTMF signals to build interactive menus.

POST /calls/{call_control_id}/actions/gather

import com.telnyx.sdk.models.calls.actions.ActionGatherParams;
import com.telnyx.sdk.models.calls.actions.ActionGatherResponse;

ActionGatherResponse response = client.calls().actions().gather("call_control_id");
