Tone 5 - Congestion: when the call cannot connect due to network congestion
Tone 6 - Number Unobtainable: when the call cannot connect due to the endpoint not being
recognised
Tone 7 - Ring Signal: announcing an incoming call.
Tone 8 – Register Fail: When a call cannot be made due to registration failure
Tone 9 - Splash 1: Announcing an incoming PAGE call
Tone 10 - Splash 2 MRTP: Announcing an incoming multicast
Each tone can be configured by setting a tone frequency (ie the note), and the cadence (ie
the timing pattern). These are normally set to simulate exchange tones common to the
phone's location, but may be configured for any purpose, for example to give distinctive ring
tones to differentiate between phones mounted close together. A table of typical tones used
in various countries is included below, and the make up of the tones is explained as follows:
Frequency
Frequency No. Tone.
1 400 Hz
2 425 Hz
3 440 Hz
4 350 Hz + 450 Hz
5 400 Hz + 450 Hz
6 480 Hz + 620 Hz
7 20 Hz + 675 Hz
8 20 Hz + 1000 Hz
9 20 Hz + 1350Hz
10 30 Hz + 2575 Hz
11 2970Hz alternating with 3380Hz at 30Hz and maxed gains
12 220Hz
13 440Hz
Frequencies 1 to 6 are commonly used for call progress, whilst 7 to 10 are usually used for
ring signals.
For example dial tone in the UK is a compound tone of 350+450 Hz, corresponding to
frequency No.4.
