Connect max232 pin 14 to phone serial cable pin 3 (Should be Rx ?)
Connect max232 pin 13 to phone serial cable pin 2 (should be Tx ?)
Connect circuit ground to phone serial cable pin 5

(If you connect it to the PC I assume you have a 9 pins DB female connector)

It should work. If it doesn't invert connections at the serial cable pins 2 & 3
