Default: 2
         

What is hwEntFxsPortImpedance?

Selects the AC line impedance profile the FXS port presents, matched to a specific country's telephony standard or handset type (e.g. 2 = 600-ohm interface, 3 = Russian interface profile, 14 = common European profile), defaulting to 2 (600 ohm). An admin sets this to match local telecom regulations or connected equipment for correct voice-signal transfer and echo performance.

Examples
