The following are IVR Options:

Normally IVR Menus only allow single digit options. However, if this setting is checked, then IVR callers (in this IVR Menu only) can dial extensions. If the IVR caller enters a valid extension, Switchvox rings the extension. If the caller enters an invalid extension, then it is considered an “invalid option,” and is handled according to that setting.
 

Options and extension dialing can coexist in the same IVR Menu. However, if you have an option in the menu (i.e.; 1) that starts with the same number as an extension (i.e.; 105) then the caller experiences a delay. When he presses ‘1’, Switchvox waits a moment to see whether he might also press ‘05’. If he doesn’t, Switchvox proceeds to option 1.
