POST https://api.vobiz.ai/api/v1/account/{auth_id}/origination-uris
Creates a new origination URI (SIP destination) for routing outbound calls from your trunk. The URI must be a valid SIP endpoint in the format sip:user@host:port or sip:host:port.
Authentication required:
  • X-Auth-ID - Your account Auth ID
  • X-Auth-Token - Your account Auth Token
  • Content-Type: application/json
Valid SIP URI Formats:
  • sip:provider@sip.example.com:5060 - Domain with user
  • sip:192.168.1.100:5060 - IP address
  • sip:trunk@sip.carrier.net:5061 - Custom port
Invalid Formats:
  • http://sip.example.com - Wrong protocol
  • provider@sip.example.com:5060 - Missing sip: prefix
  • sip:example.com - Missing port number

​
Request Parameters

FieldTypeRequiredDescription
uristringYesSIP URI destination in the format sip:user@host:port or sip:host:port. Must be a valid, reachable SIP endpoint (e.g., sip:provider@sip.example.com:5060).
priorityintegerNoRouting priority (lower = higher priority). Default: 1. Use priority 1 for primary routes and priority 2 for backup/failover routes.
weightintegerNoLoad balancing weight. Default: 10. Higher values receive proportionally more traffic among URIs with the same priority (e.g., weight 20 gets twice the traffic of weight 10).
enabledbooleanNoWhether the URI is active for routing. Default: true. Set to false to temporarily disable without deleting.

​
Response

Returns the complete origination URI object, including the auto-generated id UUID and timestamps.

Examples

​
cURL - Primary Origination URI

cURL Request
curl -X POST https://api.vobiz.ai/api/v1/account/{auth_id}/origination-uris \
  -H "X-Auth-ID: YOUR_AUTH_ID" \
  -H "X-Auth-Token: YOUR_AUTH_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "uri": "sip:provider@sip.example.com:5060",
    "priority": 1,
    "weight": 10,
    "enabled": true
  }'

​
cURL - Failover URI with Lower Priority

cURL Request
curl -X POST https://api.vobiz.ai/api/v1/account/{auth_id}/origination-uris \
  -H "X-Auth-ID: YOUR_AUTH_ID" \
  -H "X-Auth-Token: YOUR_AUTH_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "uri": "sip:backup@sip-backup.example.com:5060",
    "priority": 2,
    "weight": 10,
    "enabled": true
  }'

​
cURL - Load Balancing Configuration

Create two URIs with the same priority but different weights for 70/30 traffic split: 
curl -X POST https://api.vobiz.ai/api/v1/account/{auth_id}/origination-uris \
  -H "X-Auth-ID: YOUR_AUTH_ID" \
  -H "X-Auth-Token: YOUR_AUTH_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "uri": "sip:server1@sip.example.com:5060",
    "priority": 1,
    "weight": 70
  }'
Error Response (400 Bad Request): If SIP URI format is invalid:
Error Response - 400 Bad Request
{
  "error": "Invalid SIP URI format. Expected: sip:user@host:port",
  "code": 400
}
Best Practices:
  • Configure at least 2 origination URIs for redundancy (one primary, one failover)
  • Use priority 1 for primary destinations, priority 2 for backup/failover
  • Adjust weights to distribute load across multiple carriers or servers
  • Test connectivity to each URI before enabling in production
