I have a campaign and an attached calling list to it which runs successfully.
I see some of the contacts in the calling list were never dialed by the dialer and having disposition code as
ININ-OUTBOUND-STUCK-INTERACTION
ININ-OUTBOUND-NUMBER_COULD_NOT_BE_DIALED
Is there any way in Genesys to auto redial them since the call did not go out of the dialer in first attempt ?
The Genesys Cloud Community forum might be a better place for your question, as it focuses on configuration and use of Genesys Cloud features and capabilities.
The Developer forum foces on questions related to customization using our APIs and SDKs.
Still, I would suggest to have a look at your interactions tagged with ININ-OUTBOUND-NUMBER_COULD_NOT_BE_DIALED. According to this page, it means that "The system attempted to dial the number and received a SIP 404 response, indicating that the number does not exist."
In this case, there is no reason to dial again.
If this is supposed to be a valid number, I'd suggest you have a look at your sites and dial plans to understand why the call request received a 404 response (not found).
Regarding ININ-OUTBOUND-STUCK-INTERACTION, you can also follow the suggestion in the same Resource Center page.
