### Endpoints

The Calling API uses a variety of endpoints depending on where in the world you are located.

When using API methods concerning individual calls, you can define what regional endpoint you want to use for the call. The following regional endpoints are available:

| Endpoint | Description |
|  --- | --- |
| `https://calling.api.sinch.com/calling/v1` | Global - redirected by Sinch to the closest region |
| `https://calling-euc1.api.sinch.com/calling/v1` | Europe |
| `https://calling-use1.api.sinch.com/calling/v1` | North America |
| `https://calling-sae1.api.sinch.com/calling/v1` | South America |
| `https://calling-apse1.api.sinch.com/calling/v1` | South East Asia 1 |
| `https://calling-apse2.api.sinch.com/calling/v1` | South East Asia 2 |


For cases where the call is the result of an incoming PSTN, SIP or data call, the endpoint to use for managing that call is supplied in the ICE event. ICE callbacks will also provide region-specific URLs in the `callResourceUrl` property.

When using API methods for configuring or managing applications, where region doesn't matter, use the following global endpoint:

| Endpoint | Description |
|  --- | --- |
| `https://callingapi.sinch.com/calling/v1` | Global endpoint |
