Does SP3501 A series products support PBX connection?
SP3501AM/AS won´t have connection problem with PBX equipment. The standard RJ-11 designated PIN3/4 to transmit the data, and PIN2/5 just pass through the power. All of the manufacturers follow this standard to design and manufacture its telephone devices. Only if few customers may have their own requirements and have the non-standard designed PBX, in that case, SP3501AM/AS may fail to connect with those separately designed PBX.
