The analog speaker port is the module's power-up default active output for voice calls and DTMF tones. It
is located at pins 67 and 69 on the interface connector, named SPKR_N and SPKR_P respectively.
It is designed as a differential output with 32Ω impedance, but may also be used as a single-ended output
referenced to the module's analog ground.
The speaker output is used for both the handset and the headset audio paths.
