Hi Mohammed,
This Community thread might be helpful, as it discusses using Call Rule Sets with the Wrap-up category and the Schedule Callback action:
https://community.genesys.com/discussion/preview-campaign-retry-attempts
Although it's for a slightly different use case, it may be worth exploring whether the same approach could be applied by setting a dedicated wrap-up code (for example, CustomerNoInput) in your Outbound Call Flow and then using a Call Rule Set to schedule another attempt after 30 minutes.
I'm not sure whether this works specifically for the No Input scenario in an Agentless IVR campaign, but it may point you in the right direction. Hopefully someone who's implemented this exact use case can also share their experience.
