Invalid DISA


I use Elastix 2.2.0.
I would like create a IVR, with DISA. It is working fine, but if the phoner enter a bad DISA numer, I cant forward him a other IVR.
"Pleas press 1 and the extension you want to reach or press 9 for the operator"
If Press 9 go to extension XXX
If Press 1 go to DISA XXX

But, the dialer press 1 and press invalid DISA numer I cant forward to the other IVR. How can it?

Could You help me this problem?

Thank You!
