phone into the phone line and try to place a call.
• Check the phone number on the system programming.
• Check the phone line and make sure the telephone terminal box is grounded.
• Check if the problem occurs on all tenants.

phone into the phone line and try to place a call.
• Check the grounding on the AeGIS system and telephone line. The Aegis's
cabinet must be grounded to an earth ground. The telephone line shield must
be grounded at the telephone terminal block, not on the AeGIS cabinet.
• Disconnect the ground wire (marked GND at the 5 pins terminal) from the
board. If the problem still exists, install a Modular RFI Filter.

• Disconnect the phone line from the AeGIS system and connect a standard
phone into the phone line and try to place a call.
