306 Matrix NAVAN CNX200 System Manual
Tone standards vary with the country of application. For example, as per ITU standard, the Dial Tone for India
consists of 400Hz modulated by 25Hz, whereas it is 350+440Hz, without modulation, for USA/Canada. Further,
many countries use different frequencies and cadences for the same tone. For example, in the US, five different
frequency and cadence are used for Dial Tone.
NAVAN offers the flexibility of setting the Call Progress Tone Generation (CPTG) type to match the country-specific
CPT standards established by ITU.
India being the default 'Region' for NAVAN, the CTPG for India is set as default in the system.
How it works
At the time of installation, when you select the Region (according to the geographical location of the site where the
system is installed) and default the system, NAVAN sets the country-specific CPTG type defined for the selected
'Region'.
For countries that use different frequencies and cadences for the same tone, e.g. USA, only one
frequency/cadence among the group is considered. See
“Default CPTG Type applied to each 'Region'
supported by NAVAN” .

a. In Store and Forward dialing, the digits are first stored in a memory location and then these are dialed on the trunk.
For example: When Least Cost Routing (LCR) is enabled, the system will store the dialed digits first, check the trunk
through which the call is to be routed and then dials the number on the appropriate trunk.
