Cold Call Sales Dialer? Curious if anybody has designed a workflow that grabs a prospect from a Google sheet, calls that prospect using Twilio or similar, leaves a voicemail if nobody answers, and then once the call ends, updates and loops back to the next prospect on sheet? Any similar workflow? I guess bonus if it integrates AI Voice agent 🤓 Thank you in advance.

I am working on this workflow that pulls information from LinkedIn jobs and then curate a personal email to send using instantly. Everything is working except for the very last node that is supposed to send to Instantly. I am so close but I am totally at a loss as to why my Instantly node is not working. I have verified API key and Campaign IDs are both correct and been trying to troubleshoot in circles with LLM! Please look at the attached screenshots; perhaps it's a simple thing I am overlooking? I appreciate anybody’s insight as I’ve been racking my brain trying to figure it out. The error says: { "errorMessage": "JSON parameter needs to be valid JSON", "errorDetails": {}, "n8nDetails": { "nodeName": "Upload Lead to Instantly1", "nodeType": "n8n-nodes-base.httpRequest", "nodeVersion": 4.2, "itemIndex": 0, "time": "3/27/2025, 3:53:48 PM", "n8nVersion": "1.81.4 (Self Hosted)", "binaryDataMode": "default", "stackTrace": [ "NodeOperationError: JSON parameter needs to be valid JSON", " at ExecuteContext.execute (/usr/local/lib/node_modules/n8n/node_modules/n8n-nodes-base/dist/nodes/HttpRequest/V3/HttpRequestV3.node.js:207:39)", " at WorkflowExecute.runNode (/usr/local/lib/node_modules/n8n/node_modules/n8n-core/dist/execution-engine/workflow-execute.js:660:42)", " at /usr/local/lib/node_modules/n8n/node_modules/n8n-core/dist/execution-engine/workflow-execute.js:891:62", " at processTicksAndRejections (node:internal/process/task_queues:95:5)", " at /usr/local/lib/node_modules/n8n/node_modules/n8n-core/dist/execution-engine/workflow-execute.js:1224:20" ] } }

Has anybody put together a workflow for cold calling prospects as part of N8N sales workflow?

I’m designing an N8N workflow that interacts with a CRM and power dialer to more efficiently go through cold leads curious if anybody has done something similar? Any recommendations on a good power dialer that won’t break the bank?
