# Run evaluators over a direct SIP connection

`POST /test_framework/v2/scenarios/run_scenarios_sip/`

## Request

- Base URL: `https://api.cekura.ai`
- URL: `https://api.cekura.ai/test_framework/v2/scenarios/run_scenarios_sip/`
- Auth: one of:
  - API key in header `X-CEKURA-API-KEY`
  - HTTP bearer
  - HTTP bearer

SIP VOICE RUN (direct SIP): Execute evaluators against an agent over a direct SIP connection (orchestrated by Cekura's SIP voice service). The agent must have a SIP endpoint configured (`telephony.sip_uri` on the v2 agent).

**Custom SIP headers:** to send custom headers to the agent, attach a test profile whose `main_agent_variables` contain `X-` prefixed keys (pass its ID in `test_profile_ids`) — headers cannot be set on the agent or in this request.

**Cost:** voice-simulation rate per run.
**Run-count math:** total runs = `len(scenarios) × frequency × max(1, len(personality_ids)) × max(1, len(test_profile_ids))`.

**When to use this vs others** (pick the endpoint matching the agent's configured connection — check `aiagents_retrieve`):
- `scenarios_run_voice` — phone calls via Cekura's standard voice path
- `scenarios_run_vapi_webrtc` / `_retell_webrtc` — provider-managed WebRTC
- `scenarios_run_livekit_v2` — LiveKit (project credentials, v2)

## Request body

- SchemaPostRunScenariosSip: Schema for the run_scenarios_sip endpoint.
  - `agent_id` integer: ID of the agent to run evaluators for
  - `assistant_id` string: Alternative to agent ID - the assistant ID to use for this scenario Example: `"asst_1234567890"`
  - `scenarios` integer[]: List of evaluator IDs to run. Either scenarios, tags, or folder_path must be provided. Runs start in the order given. Example: `[11, 22, 33]` To run evaluators by tag or folder, use the `tags` or `folder_path` fields instead.
  - `tags` string[]: List of tags to filter evaluators to run. Either evaluators or tags must be provided. Example: `["tag1", "tag2", "tag3"]`
  - `folder_path` string: Dot-separated folder path to select evaluators from (e.g. `"Sales.Inbound"`). Mutually exclusive with `scenarios` and `tags`. Requires `project_id`.
  - `project_id` integer: Project ID. Required when using `folder_path` (or when passing a folder path string via `scenarios`). Example: `1376`
  - `frequency` integer: The number of times each evaluator will run. Each repeat runs the whole list in order before the next one starts (A, B, A, B), rather than grouping repeats of one evaluator. Example: `1`
  - `name` string: Label text for result
  - `outbound_phone_number` string: Override the phone number to use for outbound calls. Example: "+1234567890"
  - `personality_ids` integer[], nullable: List of personality IDs to override for this run. If not provided, uses the scenario's default personality. Example: `[123, 456, 789]`
  - `test_profile_ids` integer[], nullable: List of test profile IDs to override for this run. If not provided, uses the scenario's default test profile. Example: `[123, 456, 789]`
  - `personality_id` integer, nullable: Single personality ID override. Merged into personality_ids; prefer personality_ids for multiple.
  - `test_profile_id` integer, nullable: Single test profile ID override. Merged into test_profile_ids; prefer test_profile_ids for multiple.
  - `mode` 'same_number' | 'different_numbers': Using same or different phone numbers for each evaluation * `same_number` - same_number * `different_numbers` - different_numbers
  - `agent_number` string: Override the phone number from which the agent under test receives the call during outbound runs. This allows overriding the default agent contact number for testing purposes. Example: "+1234567890"
  - `concurrency_limit` integer: Cap on the number of evaluator runs executed in parallel. Default: unbounded (subject to your provider's rate limits). Use this to avoid hitting provider rate limits on large frequency or folder runs. Example: `5`
  - `calls_per_second` number, double, nullable: Most calls started per second for this run, a number from 0.1 to 4 (e.g. 0.5 starts one call every 2 seconds). Leave unset for no limit.
  - `mock_tool_names` string[]: Names of mock tools to activate for this run. Cekura swaps those tools' URLs to mock endpoints while the run is active and restores the originals when it finishes. Omit (or send null) to mock every tool configured on the agent; send an empty list to mock none so every tool keeps its original endpoint. Example: `["get_appointments", "cancel_booking"]`
  - `agent_version_id` string: Run against a stored version of the agent instead of the agent as it is live. Cekura makes a private copy of the agent in your provider account, puts that version's prompt on it, and runs against the copy — voice, model and tools stay as the agent is configured now, and the live agent is never changed. Accepts the version label shown in the agent's version history (`v12`, or `p1` for a version an improvement run proposed) or its numeric `history_id`. List them with `GET /test_framework/v1/aiagents/{id}/history/`; a version is usable when its `is_runnable` is true. Available for VAPI, Retell, ElevenLabs and Bland agents that are outbound and have a single prompt. Example: `"v12"`
  - `sip_endpoint` string: Override the agent's stored SIP endpoint for this run.

## Response `200`

- object
  - `id` integer: ID of the result
  - `agent` integer: ID of the agent
  - `status` 'running' | 'completed' | 'failed' | 'pending' | 'in_progress' | 'evaluating' | 'in_queue' | 'timeout' | 'cancelled' | 'scaling_up': Status of the result. Poll until it is `completed`, `failed`, `timeout` or `cancelled`. It stays non-terminal until every run has ended, then becomes `completed` if any run completed — even if runs failed their checks or others errored.
  - `run_as_text` boolean: Whether the scenario ran as text or not
  - `runs` object[]
    - `id` integer: ID of the run
    - `status` 'running' | 'completed' | 'failed' | 'pending' | 'in_progress' | 'evaluating' | 'in_queue' | 'timeout' | 'cancelled' | 'scaling_up': Status of the run
    - `scenario` integer: ID of the scenario
    - `number` string: For outbound runs (agent.inbound=False). The given number that must be called from the phone number configured in the cekura agent.
    - `inbound_number` string, nullable: For inbound runs (agent.inbound=True). The agent's configured phone number will receive calls from this number.
    - `scenario_name` string: Name of the scenario
    - `test_profile_data` object, nullable: Details of the test profile associated with this run scenario
    - `outbound_dial_window_opens_at` string, date-time, nullable: When the outbound dial window opened (run transitioned to pending/waiting-for-call). Null until dispatched.
    - `outbound_dial_window_seconds` integer, nullable: Duration of the outbound dial window in seconds.
    - `outbound_dial_window_closes_at` string, date-time, nullable: Deadline by which your agent must dial the outbound number (opens_at + outbound_dial_window_seconds). Dials after this are dropped and the run returns status: timeout.
  - `created_at` string, date-time
