Telnyx Voice Conferencing - Ruby

Installation

gem install telnyx

Setup

require "telnyx"

client = Telnyx::Client.new(
  api_key: ENV["TELNYX_API_KEY"], # This is the default and can be omitted
)

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:

begin
  result = client.messages.send_(to: "+13125550001", from: "+13125550002", text: "Hello")
rescue Telnyx::Errors::APIConnectionError
  puts "Network error — check connectivity and retry"
rescue Telnyx::Errors::RateLimitError
  # 429: rate limited — wait and retry with exponential backoff
  sleep(1) # Check Retry-After header for actual delay
rescue Telnyx::Errors::APIStatusError => e
  puts "API error #{e.status}: #{e.message}"
  if e.status == 422
    puts "Validation error — check required fields and formats"
  end
end

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:** Use `.auto_paging_each` for automatic iteration: `page.auto_paging_each { |item| puts item.id }`.

Enqueue call

Put the call in a queue.

`POST /calls/{call_control_id}/actions/enqueue` — Required: `queue_name`

Optional: `client_state` (string), `command_id` (string), `keep_after_hangup` (boolean), `max_size` (integer), `max_wait_time_secs` (integer)

response = client.calls.actions.enqueue("call_control_id", queue_name: "support")

puts(response)

Returns: `result` (string)

Remove call from a queue

Removes the call from a queue.

`POST /calls/{call_control_id}/actions/leave_queue`

Optional: `client_state` (string), `command_id` (string)

response = client.calls.actions.leave_queue("v3:550e8400-e29b-41d4-a716-446655440000_gRU1OGRkYQ")

puts(response)

Returns: `result` (string)

List conferences

Lists conferences. Conferences are created on demand, and will expire after all participants have left the conference or after 4 hours regardless of the number of active participants. Conferences are listed in descending order by `expires_at`.

`GET /conferences`

page = client.conferences.list

puts(page)

Returns: `connection_id` (string), `created_at` (string), `end_reason` (enum: all_left, ended_via_api, host_left, time_exceeded), `ended_by` (object), `expires_at` (string), `id` (string), `name` (string), `record_type` (enum: conference), `region` (string), `status` (enum: init, in_progress, completed), `updated_at` (string)

Create conference

Create a conference from an existing call leg using a `call_control_id` and a conference name. Upon creating the conference, the call will be automatically bridged to the conference. Conferences will expire after all participants have left the conference or after 4 hours regardless of the number of active participants.

`POST /conferences` — Required: `call_control_id`, `name`

Optional: `beep_enabled` (enum: always, never, on_enter, on_exit), `client_state` (string), `comfort_noise` (boolean), `command_id` (string), `duration_minutes` (integer), `hold_audio_url` (string), `hold_media_name` (string), `max_participants` (integer), `region` (enum: Australia, Europe, Middle East, US), `start_conference_on_create` (boolean)

conference = client.conferences.create(
  call_control_id: "v3:MdI91X4lWFEs7IgbBEOT9M4AigoY08M0WWZFISt1Yw2axZ_IiE4pqg",
  name: "Business"
)

puts(conference)

Returns: `connection_id` (string), `created_at` (string), `end_reason` (enum: all_left, ended_via_api, host_left, time_exceeded), `ended_by` (object), `expires_at` (string), `id` (string), `name` (string), `record_type` (enum: conference), `region` (string), `status` (enum: init, in_progress, completed), `updated_at` (string)

List conference participants

Lists conference participants

`GET /conferences/{conference_id}/participants`

page = client.conferences.list_participants("550e8400-e29b-41d4-a716-446655440000")

puts(page)

Returns: `call_control_id` (string), `call_leg_id` (string), `conference` (object), `created_at` (string), `end_conference_on_exit` (boolean), `id` (string), `muted` (boolean), `on_hold` (boolean), `record_type` (enum: participant), `soft_end_conference_on_exit` (boolean), `status` (enum: joining, joined, left), `updated_at` (string), `whisper_call_control_ids` (array[string])

Retrieve a conference

Retrieve an existing conference

`GET /conferences/{id}`

conference = client.conferences.retrieve("550e8400-e29b-41d4-a716-446655440000")

puts(conference)

Returns: `connection_id` (string), `created_at` (string), `end_reason` (enum: all_left, ended_via_api, host_left, time_exceeded), `ended_by` (object), `expires_at` (string), `id` (string), `name` (string), `record_type` (enum: conference), `region` (string), `status` (enum: init, in_progress, completed), `updated_at` (string)

End a conference

End a conference and terminate all active participants.

`POST /conferences/{id}/actions/end`

Optional: `command_id` (string)

response = client.conferences.actions.end_conference("182bd5e5-6e1a-4fe4-a799-aa6d9a6ab26e")

puts(response)

Returns: `result` (string)
