[asterisk-users] callerid not forwarded when transferring call from ISDN line to mobile phone via Asterisk

[Giorgio Incantalupo]

Hi all,

I've got 4 actors on my stage:
Alice calling from outside
Bob transferring incoming calls to Charlie
Charlie who has a mobile phone

My PBX which is connected to my ISDN line.

I want Charlie to see Alice's Callerid after Bob has transferred the 
call as if Charlie is receiving the call from  Alice, transparently.

Tried to set the callerid but Charlie sees my telco line number, not the 
callerid of Alice.

How can I do this?

Thank you.

Giorgio
