[Asterisk-Users] How an application could dialog with an external ivr ?

[FB]

an automated task (cron) DIAL an external IVR (ex: ticket reservation)
via a ZAP channel (analog line)

this automated task has to
1 - send DTMF codes in response to the IVR
2 - detect the end of each of the IVR voice messages
3 - detect IVR possible hangup
4 - detect some "bips" generated by the IVR

is there any way to maintain such a dialog between automated tasks ?
