Set Language and Timezone When Connecting To An Endpoint

Getting Started#

This snipet shows how to use languages other than English and also how to set the timezone to the timezone in which the conversation is taking place.

Utilising other languages#

Javascript SDK allows you to work with audio from multiple different languages. You can find which language the Telephony API supports here.

For timezones, please refer to this.

You can also use moment-timezone node package to obtain a list of time zones like the following const timeZones =

  1. If the language is not specified then en-US(English - United States) is used as the default language.
  2. If no timezone is passed it will default to UTC.
  3. Insights like Action items, follow-ups, topics, etc are detected for English language only.
  4. Currently, we only support up to one language.

Code Snippet#

Configuration Snippet#

Here you set the language key to Japanese: "languages": ["ja-JP"], and the timezone to Tokyo: "timezone": "Asia/Tokyo".

"operation": "start",
"endpoint": {
"type" : "pstn",
"phoneNumber": "phoneNumber"
"languages": ["ja-JP"],
"timezone": "Asia/Tokyo",
"actions": [{
"invokeOn": "stop",
"name": "sendSummaryEmail",
"parameters": {
"emails": [
"data" : {
"session": {
"name" : "My Meeting"

Full Snippet#

const {sdk, SpeakerEvent} = require("symbl-node");
const appId = appId;
const appSecret = appSecret;
appId: appId,
appSecret: appSecret,
basePath: "",
}).then(async() => {
console.log('SDK initialized.');
try {
const phoneNumber = "PHONE_NUMBER"; // Telephony API currently only supports US phone numbers.
endpoint: {
type: "pstn",
phoneNumber: phoneNumber,
languages: ["ja-JP"],
timezone: "Asia/Tokyo",
actions: [
invokeOn: "stop",
name: "sendSummaryEmail",
parameters: {
emails: [
data: {
session: {
name: "Meeting name",
}).then((connection) => {
const connectionId = connection.connectionId;
console.log("Successfully connected.", connectionId);
console.log('Conversation ID', connection.conversationId);
.catch((err) => {
console.error("Error while starting the connection", err);
} catch (e) {
}).catch(err => console.error('Error in SDK initialization.', err));


Create a javascript file named app.js and copy this code into the file. Fill in the placeholder values with the proper values. Use npm to install the required libraries: npm install symbl-node. Now in the terminal run

$ node app.js

If successful you should receive a response in the console.
