See the Dial command information at
http://www.voip-info.org/wiki/view/Asterisk+Cmd+Dial

If you specify the option "H", your user can cancel the connection to
the outward cellphone by pressing "*". You could send him back to your
IVR, or whatever. Of course they need to know about that.

In your situation, I would set the Dial() timeout to a number that is
slightly below the voicemail activation timeout (20 seconds on
non-answer or whatever). This avoids them hitting the "expensive"
voicemail of the cellular, but you could use the DIALSTATUS information
to filter them into your own voicemail IF the mobile was not answered
within the predefined time.
