Maybe others who know better will jump in - but I seriously doubt you
will be able to do this. From my limited knowledge, I believe mobile
phone networks use different signalling then regular terrestrial based
providers. I don't really think that the engaged tone sent back by the
mobile operator will be decoded correctly by Asterisk.
Not to mention that, I don't what happens where you are - but in UK for
example - you don't even get an engaged tone from a mobile phone. You
just get either sent to the user's voice mail, or you are played a
message from the mobile phone operator which essentially tells you that
the user is engaged or unavailable. Operators in many other European
countries do the same. So from the point of what you are trying to
achieve - this is useless in Asterisk.
I would have liked to do the same thing - as I have line divert in
Asterisk to my mobile phone - and I would have liked for Asterisk to
just skip along to my Asterisk voice mail when my mobile is either out
of coverage, or when I'm in a conversation on it. But no such luck. I
believe the mobile operators wouldn't like the idea anyway - as they get
to charge you extra for playing all those messages or sending you to
their voicemail.
I believe in parts of the North American continent things are similar,
but even worse. As the caller gets charged as soon as the mobile phone
starts ringing - apparently simply the act of accessing the mobile
operator's network is chargeable - never mind if you get to speak to
anybody or not.
Then again, maybe things are different where you are - and maybe there
is a way to get Asterisk to recognise the busy tone from your mobile
operator. Maybe somebody here will jump in with a suggestion. It seems
that it has to do with "busy signalling" in Asterisk. A softphone I
believe will accomplish this out of band - with some commands over SIP.
While PSTN (normal phone lines) and mobiles I believe tend to signal
this with inband tones (part of the sound coming down the line).
You might also want to check your regional settings in Asterisk.

I achieved this successfully by emulating it via a softphone, when I
call a softphone and it is currently engaged in a call, asterisk returns
BUSY in DIALSTATUS and will automatically fallback to the next step in
the dialplan.

When the target phone is currently engaged in a call, and I called the mobile phone, I can hear a "busy tone"(which is alright, since the target phone is actually busy), but it will wait until it timed out as defined in the DIAL cmd, and the "var DIALSTATUS" returns NOANSWER, instead of BUSY, as if the mobile phone is available and it was not answered at all.

At first I thought it works ok, since i tried calling a cellphone that is currently busy(phone answers 1st softphone, then another softphone calls the same number, it now returns INUSE). But then, i tried calling a different number while the first phone is busy, but it returns INUSE. It seems that the status being returned was from the peer itself(both phones uses the same peer) and not from the device(mobile phone) which i believe is more logical.
