Hi Ruben,

You should be looking at this thread 
http://lists.digium.com/pipermail/asterisk-users/2011-June/263995.html

Presently I don't have the time to generate and send logs however soon 
after my last post I did perform additional testing.

I am using ReceiveFAX using SPANDSP technology.

The occasions the System() call would not be executed, whether it was in 
'h' of the dialplan  or the main part of the macro after ReceiveFAX(), 
was when a T.38 fax was being received, when it was a G.711 fax no 
matter what I did to the call it would always execute the System() call 
whether it was in the macro or the 'h'.

Cheers,

Larry.
