The North American Numbering Plan specifies that "1+" indicates that an area code is coming, NOT a toll call. Some telcos used 1+ to indicate TOLL coming, because stepper switches could simply cut through to a smarter toll switch when 1 was dialed. But that custom was never followed in New Jersey. If I pick up a phone in NJ and dial 907-9971, I get Teaneck. 1907 gets Alaska. Easy, no? Never a timeout. Hence 1615 will always wait for 7 more digits, while 615 will wait for 4 more digits. -----
