Azure-SR plugin no-input-timeout is not triggered

[Roberto Lucchetti]

Hi All, I have an issue with the Azure-SR plugin that non sends back the no-input-timeout when no audio is received during a recognize.
The RECOGNIZE arrives with No-Input-Timeout: 10000 and the IVR did not send any audio, but nothing happen after 10s, till the client sends a STOP.

Here the log, any idea? Thanks in advance.
