Asterisk, Qsig and NEC

Hello,

I am trying to get some features to work between a NEC PBX and a Asterisk 1.6.0 server over Qsig. Calls are working fine, but on our PBX, the caller can request a “call-back” if they call a busy line. They do this with a flash-hook and a code (*10). They can cancel the call back with #10.
When I try to duplicate this feature over Qsig, it does not work. I do not think the NEC is sending the hook-flash to Asterisk (either that or Asterisk is not telling the NEC that he can accept hook-flash)

Below is what I see on the Asterisk server when I do a hook-flash (or hangup) when a called line is busy.

I am using a NEAX2400ICS 6340 J3.13. In my Asterisk server, I have a Digium TE407P

If anybody could point me in the right direction, or to someone who can fix this for me I would appreciate it. I rather pay to get this working than pay to upgrade PBX.
