Telnyx Sip - Java

Installation

<!-- Maven -->
<dependency>
    <groupId>com.telnyx.sdk</groupId>
    <artifactId>telnyx</artifactId>
    <version>6.89.0</version>
</dependency>

// Gradle
implementation("com.telnyx.sdk:telnyx:6.89.0")

Setup

import com.telnyx.sdk.client.TelnyxClient;
import com.telnyx.sdk.client.okhttp.TelnyxOkHttpClient;

TelnyxClient client = TelnyxOkHttpClient.fromEnv();

All examples below assume `client` is already initialized as shown above.

Error Handling

All API calls can fail with network errors, rate limits (429), validation errors (422), or authentication errors (401). Always handle errors in production code:

import com.telnyx.sdk.errors.TelnyxServiceException;

try {
    var result = client.messages().send(params);
} catch (TelnyxServiceException e) {
    System.err.println("API error " + e.statusCode() + ": " + e.getMessage());
    if (e.statusCode() == 422) {
        System.err.println("Validation error — check required fields and formats");
    } else if (e.statusCode() == 429) {
        // Rate limited — wait and retry with exponential backoff
        Thread.sleep(1000);
    }
}

Common error codes: `401` invalid API key, `403` insufficient permissions, `404` resource not found, `422` validation error (check field formats), `429` rate limited (retry with exponential backoff).

Important Notes

• **Pagination:** List methods return a page. Use `.autoPager()` for automatic iteration: `for (var item : page.autoPager()) { ... }`. For manual control, use `.hasNextPage()` and `.nextPage()`.

List all Access IP Ranges

`GET /access_ip_ranges`

import com.telnyx.sdk.models.accessipranges.AccessIpRangeListPage;
import com.telnyx.sdk.models.accessipranges.AccessIpRangeListParams;

AccessIpRangeListPage page = client.accessIpRanges().list();

Returns: `cidr_block` (string), `created_at` (date-time), `description` (string), `id` (string), `status` (enum: pending, added), `updated_at` (date-time), `user_id` (string)

Create new Access IP Range

`POST /access_ip_ranges` — Required: `cidr_block`

Optional: `description` (string)

import com.telnyx.sdk.models.accessipranges.AccessIpRange;
import com.telnyx.sdk.models.accessipranges.AccessIpRangeCreateParams;

AccessIpRangeCreateParams params = AccessIpRangeCreateParams.builder()
    .cidrBlock("203.0.113.0/24")
    .build();
AccessIpRange accessIpRange = client.accessIpRanges().create(params);

Returns: `cidr_block` (string), `created_at` (date-time), `description` (string), `id` (string), `status` (enum: pending, added), `updated_at` (date-time), `user_id` (string)

Delete access IP ranges

`DELETE /access_ip_ranges/{access_ip_range_id}`

import com.telnyx.sdk.models.accessipranges.AccessIpRange;
import com.telnyx.sdk.models.accessipranges.AccessIpRangeDeleteParams;

AccessIpRange accessIpRange = client.accessIpRanges().delete("550e8400-e29b-41d4-a716-446655440000");

Returns: `cidr_block` (string), `created_at` (date-time), `description` (string), `id` (string), `status` (enum: pending, added), `updated_at` (date-time), `user_id` (string)

List connections

Returns a list of your connections irrespective of type.

`GET /connections`

import com.telnyx.sdk.models.connections.ConnectionListPage;
import com.telnyx.sdk.models.connections.ConnectionListParams;

ConnectionListPage page = client.connections().list();

Returns: `active` (boolean), `anchorsite_override` (enum: Latency, Chicago, IL, Ashburn, VA, San Jose, CA, Sydney, Australia, Amsterdam, Netherlands, London, UK, Toronto, Canada, Vancouver, Canada, Frankfurt, Germany), `connection_name` (string), `created_at` (string), `id` (string), `outbound_voice_profile_id` (string), `record_type` (string), `tags` (array[string]), `updated_at` (string), `webhook_api_version` (enum: 1, 2), `webhook_event_failover_url` (uri), `webhook_event_url` (uri)

Retrieve a connection

Retrieves the high-level details of an existing connection. To retrieve specific authentication information, use the endpoint for the specific connection type.

`GET /connections/{id}`

import com.telnyx.sdk.models.connections.ConnectionRetrieveParams;
import com.telnyx.sdk.models.connections.ConnectionRetrieveResponse;

ConnectionRetrieveResponse connection = client.connections().retrieve("550e8400-e29b-41d4-a716-446655440000");
