In your example the CallerID number will always be "start".   Not what he is 
looking for.

Something like this?
[callbob]

Exten => start,1,answer

Exten => start,n,Dial(DAHDI/1/5551212,30)

If that is the case, Bob should always get the Caller ID of your asterisk 
installation - I would suggest this instead

[callbob]

Exten => start,1,answer

Exten => start,n,Set(CALLERID(num)=${EXTEN})

Exten => start,n,Dial(DAHDI/1/5551212,30)

What version of Asterisk?

1.6.1.18 

          Is the forwarding done using Followme, attended transfer or blind 
transfer?

a plain Answer plus Dial

        Hi,
        
        I'm still strugling with my CallerID presentation problem.
        Let me remind it :
        
        My setup is:
        Alice cellphone <--GSM--><--ISDN--> Asterisk <-- ISDN --><--GSM--> Bob 
cellphone
        
        Ive configured Asterisk so that whenever Bob forwards its incoming call 
to its cellphone, the later phone should present Alice's number.
        
        I was originally told that sometimes Bob would be presented Alice's 
number, sometimes the dialed number (which in this case, also match the ANI or 
the receptionnist ID).
        Now, I can't certify this ever happened : maybe, it did happen, maybe 
not.
        
        What I can certify is this:
        1. out of 32 different callers, 20 callers are presented with the 
correct number and 12 with the dialed number,
        2. all those 32 callers are cellphones operated by the same (incumbent) 
telco which also operates ISDN,
        3. Bob's cellphone is also operated by the same (incumbent) telco,
        4. all this tries were done the same day, one after the other.
        
        The best explanation I can think of is this:
        "Depending on the route used, the ANI is used instead of the presented 
caller ID".
        
        To prove that, I'll try to "record" 2 calls for the same caller and 
toward the same destination: one with the awaited presentation, one with a 
wrong one.
        (Sending this to the telco and have them change anything is an other 
story).
        
        
        Comments and suggestions are welcome.
        
        Regards
