signaling the disconnection of a phone line and the call will be considered as hangup

Specify "ON", "OFF" or a value (the power of 2) from 32 to 1024 as the number of
taps of cancellation.
Note: When configuring the number of taps, the number 256 is not translated into
256ms of echo cancellation. Instead, 256 taps means 256/8 = 32 ms. The default
setting is "ON", which is 128 taps.
