Voltage and Current monitoring are useful troubleshooting tools to test your telephone line. The typical voltage on POTS/PBX lines varies but one should expect between - 54V to - 40V when ON Hook (no dial tone) and –20 to –5V when OFF Hook. Current when ON Hook should be 0mA, when OFF Hook it should be around 23 to 35mA.
