Frequently asked questions

Ceven uses the Bolna API to send a request to the Make a phone call endpoint. When a trigger occurs in your connected SaaS tool, such as a new lead in Salesforce, Ceven identifies the correct Bolna agent ID and the customer phone number. It then sends the request to Bolna to initiate the voice interaction immediately. You can specify custom parameters in the workflow to pass specific customer data to the agent so the conversation feels personalized. The agent then handles the voice interaction while Ceven waits for the execution status to update in the background.
Yes. Ceven can pull the full list of executions from a Bolna batch. By using the Retrieve batch execution list action, the agent can scan every single call attempt in a campaign. It can identify which calls were answered, which went to voicemail, and which failed. You can then build a workflow that takes those results and updates your CRM or sends a Slack notification to your team for every successful call. This ensures that your sales team only follows up with the leads that actually spoke with the AI agent.
Ceven reads the available phone numbers directly from your Bolna account. You can use the List all phone numbers action to see what is available. Once you identify the number you want, you can use the Setup inbound call action to link a specific voice agent to that number. This allows you to dynamically shift which agent handles calls for a specific line based on the time of day or the type of campaign you are running. All number provisioning happens within Bolna, while Ceven handles the logic of the assignment.
Ceven monitors the execution status of every call it triggers. If the Retrieve agent execution status call returns a failed or disconnected state, you can configure a fallback workflow. For example, if a Bolna call fails three times, Ceven can automatically send an email or SMS to the customer instead. This ensures that no lead is dropped due to technical issues or network failures. You can set these rules based on the specific error codes returned by Bolna to differentiate between a busy signal and a system error.
Ceven is limited by the rate limits and tier gating of your Bolna account. Bolna enforces concurrency limits on how many active voice calls can happen at once depending on your subscription plan. If Ceven attempts to trigger more calls than your tier allows, Bolna will return a rate limit error. To handle this, Ceven can use a queue system where it schedules calls in smaller batches or spaces them out over time. You should check your Bolna dashboard to see your current concurrency cap to avoid interrupted workflows during high volume periods.
Currently, Ceven focuses on the execution and management of agents rather than the internal prompt engineering. You create and refine your voice agent prompts and conversational flows within the Bolna dashboard. Once the agent is configured and has a stable ID, Ceven takes over to trigger calls, manage batches, and process the results. This separation ensures that your voice design remains controlled in a dedicated environment while your operational logic lives within the Ceven workflow layer for maximum flexibility and integration.
No. Ceven does not store the raw audio files. It retrieves the execution details and transcripts via the Bolna API to determine the outcome of the call. If you need to access the original audio recording for quality assurance, you can do so directly within the Bolna dashboard. Ceven can provide you with the execution ID and a direct link to the record in Bolna, allowing you to jump from a CRM lead record straight to the audio playback in the Bolna interface.
When you use the Schedule batch action, Ceven sends the batch ID and the desired timing to Bolna. Bolna then handles the actual dialing logic and timing of the calls. Ceven continues to monitor the batch by polling the Retrieve batch details endpoint. Once the batch is marked as complete, Ceven can trigger a post processing workflow to analyze the results of all calls in that batch and generate a summary report for your team, including total reach rate and conversion percentages.
