•Echo Cancellation
Echo cancellation manually selectable to either On or Off. The default is On. The IP500 Analog Trunk Card V2 also supports echo reduction which is set to On by default.

This card supports automatic impedance matching at system startup and this mode is enabled by default. Manual or no impedance matching can be used if required. Impedance matching is supported in all locales.
