Hi Shahzad

To interface ISD chip with telephone line you need a PCM codec chip e.g. Motorola
Save This Code

MC145540
MC145500 Series

If you need the datasheets for the above, let me know I can email to you. Remote offhook detection can be tricky though, you might need to look at some Call Status monitoring chip for this purpose.

Best regards,

Imran Saeed
