Telnyx Sip - Java

Installation

<!-- Maven -->
<dependency>
    <groupId>com.telnyx.sdk</groupId>
    <artifactId>telnyx</artifactId>
    <version>6.95.0</version>
</dependency>

// Gradle
implementation("com.telnyx.sdk:telnyx:6.95.0")

Setup

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

// fromEnv() reads TELNYX_API_KEY and TELNYX_PUBLIC_KEY (the public key is required for
// client.webhooks().unwrap() — webhook verification)
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, then retry the request (bounded exponential backoff)
        Thread.sleep(1000);
        // ...retry the call here (give up after a few attempts)
    }
    throw e; // Re-throw: a failed request must never look like success to the caller
}

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

Retrieve a paginated list of access IP ranges configured on your account.

`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

Create a new access IP range on your account.

`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 an access IP range from your account.

`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)

Count connections

Returns the number of connections associated with the authenticated user, grouped by connection type, together with the connection limits that apply to the user. Forward-only connections are excluded from the counts.

`GET /connections/count`

var response = client.connections().retrieveCount();

Returns: `counts` (object), `limits` (object), `record_type` (string)

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");

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_i
