I need a complete hardware, pcb and firmware to integrate a E1 telephone project.
The project consists of a hardware that will be installed between the PSTN and the customer PBX. It will analyze only the outgoing dialed numbers and, under a certain criteria, switch certain numbers. For example, the customer dials 555-1234, and there is a criteria that determines that 555 should be replaced by 777. So, this hardware would send to the PSTN 777-1234 instead of 555-1234.
The firmware should be able to test the individual frequencies of the numbers being dialed, so it can be used as a test-set to check frequecy deviation.
Project should be developed on Microchip PIC.

We will provide a interface card between PBX and PSTN line, which will sense from PBX if some one want to dial a number. If some body dial a number it will be replaced with desired nuber as set by the user and sent to Plus
