Hi,
I'm trying to understand RFC4733, the 'named events' part mostly chapter 2 and wonder about the definition of 'state'. For a state you send with duration=0, but this is not the definition of 'state', is it?
For DTMF, is it 'Type' in table 3 that defines that DTMF events are not 'states' or what ?
3.2. DTMF Events
Table 3 shows the DTMF-related event codes within the telephone-event
payload format. The DTMF digits 0-9 and * and # are commonly
supported. DTMF digits A through D are less frequently encountered,
typically in special applications such as military networks.
+-------+--------+------+---------+
| Event | Code | Type | Volume? |
+-------+--------+------+---------+
| 0--9 | 0--9 | tone | yes |
| * | 10 | tone | yes |
| # | 11 | tone | yes |
| A--D | 12--15 | tone | yes |
+-------+--------+------+---------+
Table 3: DTMF Named Events
(In 1.4. Events, States, Tone Patterns, and Voice-Encoded Tones
'states' are only mentioned in the heading nowhere in the text, something missing ?? )
