asterisk users - Sep 2014 - GSM to GSM call with callerid passthrough

Hi All,
I have a GSM to VoIP gateway (specifically yeaster TG400) which I am trying
to use for kind of a call intercept between two GSM users. Call comes
through one SIM and goes out through another Sim with our Asterisk in
between to log the call. This works fine but we need the original callerid
to pass-through through the outgoing SIM.

I have tried every possible configuration on Asterisk that I know of but
does not work. At the moment the callerid is always of the SIM we use to
send the call out from. Has anyone tried this before? I need this very
badly.


Thanks

Unfortunately, when it comes to setting caller ID, you are basically at the 
mercy of the telco -- they can choose whether to allow it or not.  Obviously 
your telco aren't allowing you to set it, so you get the default ident for 
your SIM whatever you try to set.

Best suggestion:  Try asking nicely; but good luck with finding someone at any 
mobile telecommunications company who even understands what you are talking 
about.
