Telnyx

To use Telnyx with Edesy, register a credentials-based Telnyx SIP connection as a carrier: Edesy registers to sip.telnyx.com with your Telnyx SIP username and password, and sends calls to the sip.telnyx.com:5060 gateway over UDP. Then attach your Telnyx numbers to that connection and list them on Edesy.

Values#

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": "Telnyx",
    "requires_register": true,
    "register_username": "YOUR_TELNYX_SIP_USERNAME",
    "register_password": "YOUR_TELNYX_SIP_PASSWORD",
    "register_sip_realm": "sip.telnyx.com",
    "host": "sip.telnyx.com",
    "port": 5060,
    "protocol": "udp",
    "numbers": ["+1XXXXXXXXXX"]
  }'

2. Configure Telnyx#

1. In the Telnyx portal, create or open a SIP Connection with Credentials authentication and copy the username and password into the request above.
2. Assign your numbers to that connection.
3. Make sure the connection allows the codecs Edesy uses: G.711 μ-law and A-law.

Because Edesy registers, Telnyx delivers inbound calls on those numbers to Edesy over the registration.

3. Test#

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

FAQ#

Can I use IP authentication with Telnyx instead?#

Telnyx also offers IP-authenticated connections. In that case leave requires_register off, add Edesy's signalling IP on the Telnyx side, and set the inbound destination to the Edesy SIP address from onboarding.

Registration fails.#

Check the username, password and realm, and that the connection uses credentials authentication.
