Description

List every phone (CALL) asset on a campaign, with status and resource names.

duplicate), or to find the asset/link to pause or remove.

**Parameters:**
- campaign_id: The campaign ID (REQUIRED). Get from list_campaigns.
- customer_id: Optional Google Ads customer ID

**Returns:** each call asset's phone_number, country_code, status
(ENABLED/PAUSED), asset_resource_name, and campaign_asset_resource_name.

**Execution time:** 1-2 seconds (read-only)

**Example:**
User: "What phone numbers are on this campaign?"
Agent: list_call_assets(campaign_id="19850524478")
