Modify the sample code

1. Download the application from Github in order to get started. You will need to have Git installed on your machine. If you are new to git or need to install git, please visit this documentation from Github.

   In terminal, insert the following:

   git clone https://github.com/nexmo-community/smart-number-smart-ivr-fallback-demo.git cd smart-number-smart-ivr-fallback-demo

   widgets.copy

2. Next, install the dependencies:

   npm install

   widgets.copy

3. Navigate into the cloned repository and create a new file called .env.

4. In the .env file, add the following

   widgets.copy

   CALLER_ID=''
   DEST_TYPE=''
   DEST_NUMBER=''
   DEST_EXT=''
   DEST_SIP=''
   FALLBACK_TYPE=''
   FALLBACK_NUMBER=''
   FALLBACK_EXT=''
   FALLBACK_SIP=''
   VOICE_NAME=''
   PORT=''
   

   Enter the appropriate value for each environment variable:

   Key	Description
   CALLER_ID	The caller ID used for outbound connections.
   DEST_TYPE	The type of connection to which the hotline should connect.
   DEST_NUMBER	The PSTN number to connect. This is used when DEST_TYPE is set to phone.
   DEST_EXT	The Vonage Business Communications extension number to connect. This is used when DEST_TYPE is set to vbc.
   DEST_SIP	The SIP URI to connect. This is used when DEST_TYPE is set to sip.
   FALLBACK_TYPE	The type of connection to which the hotline should connect.
   FALLBACK_NUMBER	The PSTN number to connect. This is used when FALLBACK_TYPE is set to phone.
   FALLBACK_EXT	The Vonage Business Communications extension number to connect. This is used when FALLBACK_TYPE is set to vbc.
   FALLBACK_SIP	The SIP URI to connect. This is used when FALLBACK_TYPE is set to sip.
   VOICE_NAME	The Nexmo voice to use for text-to-speech.
   PORT	The port on which the application should listen.

5. In this example, the application will dial a PSTN number when there is a call to the Smart Number.

   In the .env, update the following:

   widgets.copy

   CALLER_ID={a valid PSTN number}
   DEST_TYPE="phone"
   DEST_NUMBER={phone number to dial}
   FALLBACK_TYPE="phone"
   FALLBACK_NUMBER={phone number to dial}
   PORT=3000
