### Answer Based on the available sources, I don't have specific documentation comparing Aircall vs Google Sheets vs other solutions for use with Retell AI. What I can tell you from the sources is how Google Sheets is used with Retell AI: - Google Sheets can be used to pull contact info for outbound calling campaigns [(1) ]() - You can personalize each call based on spreadsheet data - The sheet can be updated after each call with results (like appointment confirmation status) - This is typically connected through automation platforms like N8N or Make - You can set up triggers (e.g., daily at 8 AM to check new rows and initiate calls) For handling call concurrency with large volumes, there are endpoints available and workarounds like limiting to batches (e.g., 20 calls, then wait a minute before the next batch) . I don't have documentation on Aircall integration specifics or a direct comparison between these solutions. If you need more details on alternative integrations, I'd suggest: - [Retell AI GitHub]() - [Contact Sales]() Would you like a general answer based on my knowledge, or do you have a more specific question about Google Sheets integration?
