Instead of jumping between tabs to find a customer's history or checking if a message was delivered, your agent handles it all in one go. It can pull up specific call details, look through your contact list, and even grab call recordings for quality checks. If you're running a sales team, it can monitor your dialer campaigns or see which agents are handling which messages. It makes the communication side of your business feel like a single, connected brain. You'll find it's a lot easier to manage high-volume outreach when your agent knows exactly who it's talking to and what happened in the last conversation. It's one of the many tools you can find in the Vinkius catalog to bridge the gap between your phone system and your AI workflows. ## Tools ### create_contact Create a new contact ### get_account_profile Get my profile ### get_call_details Get call details ### get_contact Pulls phone numbers, emails, and metadata for a specific contact to help with customer vetting. ### get_message_details Get message details ### list_account_numbers List JustCall numbers ### list_team_users List team members ### send_message Send SMS/MMS ### list_calls Lists all call directions, durations, and statuses to audit communication activity. ### list_contacts Lists names and phone numbers to search for customers or provide contact info. ### list_messages Lists SMS and MMS content and delivery status to monitor text-based interactions. ### list_webhooks Lists all configured webhooks to audit your system integrations. ## Prompt Examples **Prompt:** ``` Did we talk to this customer last week? ``` **Response:** ``` I'll check the recent call history for that customer. | Date | Duration | Status | Notes | | :--- | :--- | :--- | :--- | | Oct 24 | 05:12 | Completed | Customer requested a refund for order #123.
