Once you list your business - it only takes about 2 weeks from when you create a business page to when the confirmation code is received. Once you input that code in, Google Maps will start displaying your business listing with your permanent number. Google Search will also show the info box on the right hand side of the search result page when people search for your business.
This way, the dynamic number insertion will not affect the phone number listed on the google search page.
