Hello @Saugort Dario Garcia
First of all thanks for your answer.
I have been analyzing what you tell me
We use a genesys campaign in which we introduce the registers through a data action, in a queue call flow

The problem we have is that we send the record generation date
What makes a row with the phone number X no different from another row with the same phone number X
The date of sending a registration is important to us.
Since we use it to order the output of contact list records
We are going to continue working on your suggestion but if you can think of a way to solve the problem
We would appreciate it if you let us know
Thank you so much

Hi @Juan Carlos Fernandez
Could you explain a little more about how you implement your "call me back system", you use an always on Genesys Cloud campaing or callback API?
If you use Genesys Cloud campaing, according to the info, if you upload a new contact and it match with an already loaded contact, it can be updated instead of append it. Look at: https://help.mypurecloud.com/articles/append-records-contact-list/
