| Description | This object identifies an optional end code used when the
pktcSigDevVmwiSigProtocol is set to a value of
'dtmf(2)'. Different countries define different on-hook
Data Transmission Protocol signaling codes to support
VMWI.
When Dual-Tone Multi-Frequency (DTMF) is used, the VMWI
digits are preceded by a 'start code' digit, followed
by the digit transmission sequence ... (where
Sx represents the digits 0-9), and terminated by the 'end
code' digit.
For example,
... ... ... .
The DTMF code 'C' may be sent by the network as an end code
for the transfer of information values, through which
special events can be indicated to the user. In some
countries, the '*' or '#' may be used instead of 'A',
'B', 'C', or 'D'.
The value of this MIB object MUST NOT persist across MTA
reboots. |
