Cannot get Recognize Speech Task to work on Collaboratory

[aprokop]

I created two options:

DTMF:1 Speech Key: YesKey Phrases: Yes
DTMF:2 Speech Key: NoKey Phrases: No

I mapped the incoming ucid to udid for the task.

When I run my workflow, it sits at that task for many seconds before I hear "A serious error has occurred exiting." It doesn't matter if I press any digits or say anything.

I see this in the admin debug window.

{'ucid':'00500049581467228046'} {'__sid__':'EngagementDesig-3.1.0.1.09009-4feb0c681c0a45232d6371c6d73ee630bbc7e5ccc7c78c8766 1fa1b747b10ebc','choice':''} none Communication tasks

This same problem occurs with WFD created by Avaya.
