I want to add a button to a contact record to open a phone call record in creation mode with populate some data from that contact record. is that possible?

There’s already a button on the contact form under communication->activities. That opens a phone call popup, which populates the company name, contact etc. Modify the phone call form & add your own script to it to populate whichever extra fields you require.

I don't want to use that and I want to create my functionality and use it across other types and records as well
