ASL3 Simplex AutoPatch - VOX not working

[K2IE]

I am in the same situation, as I recently posted in:

Autopatch with ASL 3.0

There is good news and there is bad news. autopatch no longer causes app_rpt to hang when initiating a call. I can succesfully ring through to an extension on my internet pbx over iax. I can pass audio from a radio to the extension. However no audio is passed back from the phone to the radio. If there is a VOX function it does not appear to work.
