FreePBX 2.2b3 and DISA

I seem to be having a problem with DISA.

I have configured it so when I call my PBX it hangs up on me and calls me back which it does.

It then presents me with a dial tone but as soon as I press a key Asterisk issues a hang-up.

I don’t have a password on DISA so when the PBX calls me back it does not ask for a password which it use to do in earlier version which is good but the hang-up problem once a key is pressed is a problem.
