Vonage

Vonage (formerly Nexmo) is a cloud communications provider that supports voice calls and SMS.

Setup

1. Create a Vonage Application

Go to the Vonage Dashboard and create an application with Voice and Messages capabilities.

2. Configure webhook URLs

Set these on the Vonage dashboard:

Webhook	URL
Answer URL	{BASE_URL}/webhooks/answer
Event URL	{BASE_URL}/webhooks/event
Inbound SMS	{BASE_URL}/webhooks/inbound-sms
SMS Status	{BASE_URL}/webhooks/sms-status

Replace {BASE_URL} with your server's public URL (the BASE_URL environment variable).

3. Add to Svarla

Via the web interface or API, add a Vonage provider with:

• API Key
• API Secret
• Application ID
• Private Key (the .key file content)

Audio routing

Vonage call audio goes through the MediaBridge via SIP. When a call connects, the Server instructs Vonage (via NCCO) to use a connect action with type sip, pointing to the MediaBridge's SIP port (5060).

TIP

Make sure your MediaBridge's SIP port (5060) is accessible from Vonage's infrastructure.
