Description

 

 

 

 

 

Speakerphone Type Selection: This command determines which speakerphone type is used when

 

 

the modem receives a +VSP=m command. This allows the application software to select whether

 

 

telephone emulation or digital speakerphone is used for +VSP=m. Upon powering-up, the modem

 

 

determines whether it can support a digital speakerphone mode. If digital speakerphone is supported,

#VSPS=m

1

then the factory default value is equal to ‘1’. If the digital speakerphone is not supported, then the

factory default is ‘0’.

 

 

 

 

Range: 0, 1
