as know can inquire android dial number you:

uri number = uri.parse("tel:" + numberstring); intent dial = new intent(intent.action_call, number); startactivity(dial);

but on stock android, cannot interact dialer application after have dialled number.

however, can tell dialer set pause between numbers:

either 2-second pause, or indefinite wait.

to come in 2-second pause between numbers, utilize "," in dial string:

"6581329445,303" (thanks @323go)

to wait indefinitely, utilize ";" in dial string:

"6581329445;123"

this can more useful in situations - depends on how long automated answering service take allow come in extension.

the indefinite pause handled dialer popping dialog in dialler app, allowing user send numbers.
