asterisk users - Sep 2014 - error receiving a fax ... but with a fax that was received without problems

Dear all,

When receiving a fax, the extension is "spawned", despite nothing but
positive messages (see below)

The sending fax considers it a success & the verbose output of asterisk
gives a "FAX_SUCCESS" and a "NO_ERROR" error in the
ReceiveFax command.

The problem is that all the next steps (conversion of the fax to pdf &
sending it to a mailbox) are never executed.  When I do this manually,
there seems nothing wrong with the received file ....

Any hints ?

Asterisk output:

*    -- *Executing [502 at LocalSets:5] *ReceiveFAX*("*DAHDI/4-1*",

*/tmp/201409211416.tif*") in new stack

After the fax is completed the call is hung up so subsequent dialplan 
logic does not execute. You need to place the rest in the 'h' extension 
which is executed upon hangup.
