Hi
you need the "hard to find" crosspoint switches, a good knowledge of telephone operation and signaling and the firmware for the pic maybe is the easier part of this project...

Hi,

Why you want to change the controller; it is working fine with 8051.

We are trying to update the whole on ARM 7,

If you have any idea; please suggest.
