EIG-8O Gateway Administration Guidelines
MAG-06008 Rev. A
port is set to 8 ports at least. If RTP has less than 8 ports
，
4 lines can not be used at the same time.
EIG-8O adopts 8 FXS ports at the most. So it is highly recommended you set RTP to 16 ports. Default
is 10010 ~ 10030. You do not need to change it.
First Digit Timeout
In the
First Digit Timeout
field enter the time (in second) allowed for the dialing of the first digit. When
a line goes off-hook, if within the time specified here the first digit has not been dialed, EIG-8O will treat
this as an abandoned call and will indicate to the caller to place the phone on hook. The default value
is 12 seconds.
Inter Digit Timeout
In the
Inter Digit Timeout
field enter the time (in second) allowed for the dialing of the middle digits.
Counting from the last digit dialed, if within the time specified here no digit has been dialed, the system
will send the dialed digits out. The default value is 12 second.
Dialing Finish
In the
Dialing Finish
field enter the time (in second) for finished dialing. This parameter is used in
conjunction with x.T in the dialing rule. After the specified head of the number in the rule has been
dialed, if within the time specified here no digit has been dialed, EIG-8O will send the dialed number
out. The default value is 5 seconds. For example, there is 021.T in the dialing rule. After the caller dials
021, if within the specified time (for example, 5 seconds) no digit has been dialed, 021 will be sent out.
DTMF Mode
In the DTMF Mode field select the transmission mode. This parameter is used to set DTMF signal
transmission mode. Options are Audio mode, 2833 mode, and INFO mode. The default setting is Audio
mode. Audio mode is a transparent transmit mode; INFO mode is information transmit mode; 2833
mode is a RTP data packet transmit mode.
Default Codec
In the
Default codec
field select the codec EIG-8O supports. EIG-8O support G729A/20, G723/30,
PCMU/20, PCMA/20, GSM, iLBC codec as well as manifold encoding modes at the same time.
Multiple values are demarked by commas. When manifold encoding mode is selected, the gateway will
process the communication by selecting the encoding mode front to back, which is supported by both
sides.
