4.5.1 Codecs
There are 3 audio codecs available, coded as follows:
G.711a = 8
G.711u = 0
G.729 = 18
Codecs required are entered in the desired preference order, separated by spaces.
For example, to use G.711a as the 1st preference and G.711u as the 2nd preference, the
string should be entered as just:
8 0
4.5.2 Button map string
The button map string defines the functions of all available pushbuttons and keypad keys,
plus the 4 logic inputs and the hookswitch.
The maximum number of pushbuttons or keypad keys is 18, so with the 4 inputs and the
hookswitch there are 23 inputs which can be defined.
The button map string therefore consists of 23 codes separated by spaces.
IMPORTANT: Ensure there are no leading spaces at the start of the string.
The position of each code within the string maps it to a button or input. In other words the first
code defines the function of button 1, the second code defines button 2 and so on. The final
(23rd) code defines the function of the hookswitch.
The buttons/inputs are (In order):
[1 - 18]: Keypad buttons, see diagrams below.
[19 - 22]: External inputs 1 - 4
[23]: Hook switch
The physical locations of the buttons on different models of telephone are shown in the
