Where is callback module function?

Hi Freepbx,

2 years ago, I configured a DISA inbound with a Callback function.
So a recognized cid would get directly disconnected when calling to our pbx and was called back with a DISA function. So you can call through the pbx without costs for mobile usage.

But now I cannot find the CallBack module anymore.
Is it gone or hidden in FreepPbx Distro 2.10 and 2.11? or am I overlooking something here.
Many thanx in advance.

It is their. Called callback

Tony, tthank you,
Still cannot find it, where do I have to look?
Many thanx
