Service Center Call & WhatsApp Automation

I run a service center and I’m ready to streamline two key touch-points at once: inbound customer support calls and WhatsApp messaging. I am not working on CRM and ticketing system, so the solution must plug directly into both of those platforms—ideally through secure APIs or webhooks—so every interaction is logged automatically without any manual data entry. I only need straightforward rule-based flows: IVR menus for phone calls, and button- or keyword-driven replies on WhatsApp. Natural-language understanding is not required; speed, reliability, and clear routing rules are the priorities. Please propose the tech stack you’ll use (Twilio, 360dialog, Asterisk, Vonage, Dialogflow CX in “no-NLP” mode, or any other you prefer) along with the integration method for my existing CRM and ticketing tools. A brief outline of how you’ll handle testing and hand-over training will help me evaluate fit. Deliverables should include: • Fully configured call and WhatsApp workflows connected to my CRM and ticketing system • Clean, commented source/config files or low-code assets • Step-by-step deployment and rollback guide • One round of live testing with my team and post-launch tweaks If you’ve built similar automations before, sharing a brief example or demo will speed up the decision.
