| Description | This object identifies optional end codes used when the
pktcSigDevCidSigProtocol is set to a value of
'dtmf(2)'.
Different countries define different caller id signaling
protocols to support caller identification. When
Dual-Tone Multi-Frequency (DTMF) is used, the caller id
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. |
