DTMF char or
Note
It is sometimes difficult to recognise the above-described situations
reliably due to a poor quality of the PSTN connection. Excessive noise in
the surroundings may also have a negative impact. However, this may
only decelerate automatic dialling (the busy tone may not be
recognised, e.g.). Even if the intercom cannot identify the DTMF, the
connection is established (yet for a shorter time).
