I've been trying to develop my own EPOS system for a takeaway and I want to include a telephone receiver feature.
Basically, when a customer calls on the landline number, the number should be shown on the java application. How do I go about doing that?
I had a look online and I found JTAPI but I don't really know how to implement it and whether it'll work with analog phones.
Thanks in advance for the help!
Edit: Just to add some more details: I currently just have a laptop and a regular analog phone. Could I set something up with that alone, or would I need some more hardware?
