Please note!
The number of tone to be detected before terminating the call should not
have a too small value. If this is the case it might be that the device can
detect normal speech as a busy tone and truncate the call. We suggest to not
use values below 3.
Ring back tone detection
The Doortello Business can count the numbers of rings sent to the called party by
detecting the ring back tone. As default the ring back tone detected is the standard
1000 make and 4000 break tone. If needed you can change this tone following this
procedure:
OK tone
{make 1 in ms x 10}
OK tone
{break 1 in ms x 10}
OK tone
{make 2 in ms x 10}
OK tone
{break 2 in ms x 10}
OK tone
The make values 1 and 2 (duration of the tone) and the break values 1 and 2 (pause
of the tone) can be between
and
.
Example:
You want to detect a double ring back tone with a make of 250 ms (25 x 10), a
break of 500 ms (50 x 10), a second make of 250 ms (20 x 10) and a second break of
4000 ms (400 x 10) duration. Input:

Please note!
If you want to program a ring back tone with a single make and break you
have to use only the values make 1 and break 2. The values break 1 and make 2
have to have in this case a value of 000.
