Parameter Description
MGCPDTMFDetectionPoint
ƒ
[0]
= DTMF event is reported on the end of a detected DTMF
digit.
ƒ
[1]
= DTMF event is reported on the start of a detected DTMF
digit (default).
KeyBlindTransfer
Keypad sequence that activates blind transfer for Tel-to-IP calls.
There are two possible scenarios:
ƒ
Option 1:
After this sequence is dialed, the current call is put on
hold (using Re-INVITE), a dial tone is played to the B-channel,
and then phone number collection starts.
ƒ
Option 2:
A Hook-Flash is pressed, the current call is put on
hold, a dial tone is played to the B-channel, and then digit
collection starts. After this sequence is identified, the device
continues the collection of the destination phone number.
For both options, after the phone number is collected, it's sent to
the transferee in a SIP REFER request (without a Replaces
header). The call is then terminated and a confirmation tone is
played to the B-channel. If the phone number collection fails due to
a mismatch, a reorder tone is played to the B-channel.
Note:
It is possible to configure whether the KeyBlindTransfer code
is added as a prefix to the dialed destination number, by using the
parameter KeyBlindTransferAddPrefix.
KeyBlindTransferAddPrefix
Determines whether the device adds the Blind Transfer code
(KeyBlindTransfer) to the dialed destination number.
ƒ
[0]
Disable (default).
ƒ
[1]
Enable.
VoicePayloadFormat
Determines the bit ordering of the G.726/G.727 voice payload
format.
ƒ
[0]
= Little Endian (default)
ƒ
[1]
= Big Endian
Note:
To ensure high voice quality when using G.726/G.727, both
communicating ends should use the same endianness format.
Therefore, when the device communicates with a third-party entity
that uses the G.726/G.727 voice coder and voice quality is poor,
change the settings of this parameter (between Big Endian and
Little Endian).
