To use Vonage with Edesy, register an IP-authenticated carrier whose gateway is sip.nexmo.com on port 5060 over UDP, with no registration. On the Vonage side, allow Edesy's signalling IP for outbound calls and set your Vonage numbers to forward inbound calls to the Edesy SIP address you get during onboarding.

Values#

Setting	Value
Auth to Vonage	IP-based (`requires_register: false`)
Gateway	`sip.nexmo.com`, port `5060`, UDP
Inbound target on Vonage	`sip:<number>@<edesy-sip-address>:5070`

1. Register the carrier on Edesy#

curl -X POST https://voice-api.edesy.in/v1/trunk-portal/trunks \
  -H "Authorization: Bearer sk_YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Vonage",
    "requires_register": false,
    "host": "sip.nexmo.com",
    "port": 5060,
    "protocol": "udp",
    "numbers": ["+44XXXXXXXXXX"]
  }'

2. Configure Vonage#

In the Vonage dashboard, add Edesy's signalling IP to the IP addresses allowed to send SIP to your account.
For each number, set inbound calls to forward to a SIP URI at the Edesy address from onboarding.

3. Test#

Outbound: POST/v1/calls with from set to one of your Vonage numbers.
Inbound: dial the Vonage number.

FAQ#

Outbound calls are rejected by Vonage.#

Check that Edesy's IP is allowed on your Vonage account and that the caller ID is a Vonage number you own.

Does Vonage need a tech prefix?#

Not usually. Use tech_prefix only if your Vonage account requires one.
