If you can use tone dialling, the amount of time it takes to dial can be changed using the S11 register. It gives the duration (in 100hundreds of a second) to send each tone while dialling. The default is usually 95 (almost a second.) How fast you can dial depends on the phone company's switching equipment which handles your line. The minimum duration is 50, almost twice as fast, and that speed often works.
