You should always specify the switchtype and signaling parameters for
ISDN issues as well.  In this case it is not critical to determine
what is happening.

Asterisk does not care about the response from the switch in this case
so it does not wait for the defined response before hanging up the call.
DAHDISendCallreroutingFacility always returns nonzero to hangup the call.
I think it needs to have a built in wait(5) after sending the request
before returning to accommodate switches like yours that need time to
process the request.

Please file a bug report on this so it does not get lost.
