IVR post queue's caller hangup

Hi all
i wonder was what the best way to let queue agents (after caller hangup) to enter an ivr to make post call surveys ?

Do you need post call survey for Agents? I have normally seen that for callers but not for Agents.
You can have a look at F option of Queue application

F( context^exten^priority ) - When the caller hangs up, transfer the called member to the specified destination and start execution at that location.

It’s not properly a survey but similar…
My queue is an external number called via voip trunk…
Do you think this could work?

Yes that will work irrespective of channel technology used for Agent.
