What is acFMCommonRelayVolume?

This signed integer (-18 to -3) sets fax gain in dBm: range -18.5 to -3.5 dBm in 1 dBm steps. Network engineers adjust this to prevent fax tones from overloading voice cards or being too weak for modems to detect reliably. A value of -12 targets -12.5 dBm fax volume, typical for stable fax modem handshakes.

Examples
