Fallback not work

[MZKc]

A call arrives through E1, goes to the URA, option 5 sends to a group with two extensions that has a 15-second fallback to another group,this fallback sometimes works and sometimes it doesn't. When it works, the other group has another fallback that sends to another group or extension, this fallback never worked.

The group fallback settings are in the image. The default no response setting is 300 seconds.

What's an URA? What release and type of IP Office?

Stuck in a never ending cycle of file copying.

URA is IVR. IP office release is 11.1.2.1.0 build 3.

Using the overflow I can put the extensions to which it should ring, but using the fallback does not work.
