Hi everyone,

I am developing an integration of a third party phone. My development is based on a server that contains the phone served by iframe in a html accessed by Hubspot on localhost (by setting the url of the Calling Settings endpoint). At this point, my problem is that I don’t find the way (endpoints) to obtain and retrieve contact information. My objective is to retrieve the phone number that the user is going to call. At this point the user clicks on the phone number of a contact, the widget is displayed and the phone runs but there isn’t any information send to the server.

I hope someone has the solution for this, thanks for reading!  
P.D. Sorry I recently posted this on Ideas board by error

Hi, @AFranco98 👋 Thanks for your question. I’d like to invite some of our community members t the conversation — hey @himanshurauthan [@zach\_threadint](https://community.hubspot.com/t5/user/viewprofilepage/user-id/324811), do you have any recent experience with the project goals @AFranco98 is describing? Or more generalized advice for working with the calling SDK?

Thank you very much for taking a look! — Jaycee

Thank you for answering, another question related is if there is some way to control or manipulate the calling button on a contact? I forgot to ask this yesterday and is very related to my interests on the previous question, thank you again!!
