Codec Negotiation
The following table indicates which codec will be selected depending on
which codec is selected on each phone, a G711 always option is included
because some non-Siemens phones may include this option.
Note that the table is read with Phone A calling Phone B. The table is not
symmetrical so does not describe the situation if B calls A. If a call is
cleared because the codecs are not compatible, the phone will display "Ter-
minal Incompatible".
