Hello,

There appears to be a delay of 1 second between menu events within an IVR (i.e. play long, invalid option, play short).

We have the following IVR menu;

          <menu name="ivr.2"
              greet-long="phrase:demo_ivr_main_menu"
              greet-short="phrase:demo_ivr_main_menu"
              
              exit-sound="phrase:demo_ivr_main_menu"
              confirm-macro=""
              confirm-key=""
              confirm-attempts="3"
              timeout="10000"
              inter-digit-timeout="10"
              max-failures="3"
              max-timeouts="3"
              digit-len="1">

In the above example, any option will result in an invalid selection being met.

However, FS seems to take its sweet time getting from the point of a user pushing a button, to actually playing the next audio.

In the above, you can see the IVR knew the menu was invalid at "16:17:21.872105", but didn't start playing the next audio until "16:17:22.872155".

The difference between the two is almost exactly 1 second, which makes me think maybe there's a config option somewhere that isn't documented/obvious, or a hard coded delay.

Any advice on this would be much appreciated, slow/laggy menus are a pet hate of mine :/

Thanks

Cal
