What is twoWireSourceChannelCompandingLaw?

This read-only OID reports which companding law (mu-law or a-law) is encoding the audio samples from the two-wire channel. Engineers check this to verify the channel matches regional voice standards—mu-law for North America/Japan or a-law for Europe and most other regions. For example, reading "muLaw" confirms the analog voice is being digitized using the North American standard, ensuring proper audio quality and interoperability.
