Provided the endpoints and the Device Adapter are configured to provide the correct country setting for each endpoint, the endpoints receive the in-band tones either from the remote side (typically as audio in the RTP stream) or as locally generated tones from the Device Adapter.
Note:
Device Adapter does not support media tones through Avaya Aura® Media Server. The tones are generated either by the MGC resources or by the endpoint itself.
