Example call
A customer calls Sunday to say their car is overheating. AssistCall takes an urgent message with their name, number and vehicle and books a Monday 8 am slot. The service writer reads the summary and opens the repair order in R.O. Writer.
- Forward the shop line to AssistCall after hours or on overflow, so callers can book an appointment or leave a message.
- Email the service writer a summary, transcript and recording link for each call, so the repair order can be opened in R.O. Writer.
- Send call.completed events by webhook to an HTTPS endpoint the shop controls, for a searchable call log.
How it connects
- Call forwarding: Forward your business line to AssistCall when busy, after hours or always. Works with any carrier.
- Webhook: Signed JSON for every call, message and booking, sent to any HTTPS URL you choose.
