I'm trying to setup a strategy using Call Pacing Type based on skill. It only shows inbound skills.
I have configured the Nailer application but I run the campaign but I'm not able to get Nailed. See attachment.

I'm not sure how should it work. The official documentation is not clear enough to me.

Skills based Pacing is for Agentless Campaigns ONLY.
Nailing an agent is only used in Agent Campaigns (manual/preview/progressive/expert/cruise type pacing)

Using the "Avaya Agent" node allows the called party to be transferred to a VDN after a message is played.
The confusion is that in the guide, the "Avaya Agent" node is referred to as an "Agent campaign".

Use Case 1: Make a call, play a message, transfer the call to a VDN
You can use skill based pacing (as long as you have RT_Socket running on the CMS) and you'll use the "Avaya Agent" node like in your image.

Use Case 2: An Agent logs into a POM desktop application, goes ready, gets a nailup call from POM, and the is joined to a campaign using one of the manual/preview/progressive/expert/cruise type pacing types

See POM shipped applications in the Using Guide.

Thanks a lot MikeMalcorINI! It is clear.
I'll put later a new post asking some more details for "Desired Value" for EWT Parameter.

Best regards,
