183A Toll corridor dispatch math kills callback windows
A shop running two trucks out of Anderson Mill or Twin Creeks faces 15–20 minute drive times to Leander, 25 minutes to Liberty Hill, 18 minutes to Brushy Creek-North during evening commute hours on 183A Toll and Parmer Lane. When a no-cool call hits at 5:30pm in Cypress Creek and your truck is wrapping a compressor swap, the four-minute callback window closes before you clear the job site. The homeowner in Buttercup Creek books the next shop by the time you reach your phone. Narlo sends the SMS reply in 10 seconds from your Cedar Park number, qualifies the address along RM 1431 or Highway 45, and holds the lead while your truck finishes. The booking lands in your CRM with the customer in Round Rock expecting your arrival window, not a competitor's.
