Sidetone is enabled by default on Dreamwave Phones running release 2.41.0.10 (D28P) & 6.41.0.10 (D26P) onwards.
Sidetone is the effect of sound that is picked up by the telephone's mouthpiece and introduced (at low level) into the earpiece of the same handset, acting as feedback. The phone network must ensure that not too much of the caller's voice is fed back into his or her receiver. This is achieved by phasing the signal so that some cancellation occurs in the network before the signal is fed to the receiver.
