I have developed Open CTI lightning (softphone) in Salesforce as a pop up for incoming and outgoing call. I am facing this problem as the telephone system vendor they do not have adapter to communicate with Salesforce.
What I have done is, I have created one REST API service for them to send phone number and data through this service to Salesforce.
I want to know that is there anyway to trigger screen to pop up from the data send through REST API as an incoming call or is there any other way to overcome this requirement.
Thank you so much.
