Description:When dial(IAX2/) an extension that does not exist, Asterisk sends back a REJECT with cause code 3 (invalid extension) but the receiving side does not pass the cause code back.


This is a major problem because it's impossible to tell why the call failed.  Dial() gets a cause code of 0 and an AST_CONTROL_CONGESTION, so your DIALSTATUS becomes CONGESTION, which means you have no idea that it's invalid.

The attached patch simply copies over the received cause.  This allows you to check the HANGUPCAUSE and deal with cause code 3 properly.
