• With the option Encoder follows Decoder on incoming calls you ensure
that the Encoder always works with the same settings (such as e.g. Audio
coding algorithm and sampling frequency) as the Decoder does.

If you select G.722 (7 kHz), the system signals to the remote side that only a 7 kHz Decoder is
available, although you have an MPEG Decoder with MAGIC AC1. In this way, the remote side
is forced to encode with 7 kHz.
TIP
Since some Audio codecs only allow the same parameters in transmit and re-
ceive direction, this setting should be always enabled to guarantee maximum
compatibility.
This setting only refers to incoming calls. If you establish a connection your-
self, you can select different parameters for Encoder and Decoder if the called
end supports this configuration.
