Special Features
This parameter specifies the mechanism to transmit DTMF digit. There are 3
modes supported: in audio which means DTMF is combined in audio signal
(not very reliable with low-bit-rate codec), via RTP (RFC2833), or via SIP
INFO. Multiple selections of DTMF method are supported.
This parameter sets the payload type for DTMF using RFC2833
Default is "No". If set to "Yes", flash will be sent as a DTMF event.
The amount of time the hookflash is pressed that will cause the device to
onhook. Default is 800ms.
Selects the impedance of the analog telephone connected to the Phone port.
Select the Caller ID Scheme to suit the standard of different area.
• Bellcore (North America)
• CID-Canada
• DTMF-Brazil
• DTMF-Sewden
• DTMF (Denmark)
• ETSI-DTMF (Finland, Sweden)
• ETSI-FSK (France, Germany, Norway, Taiwan, UK-CCA)
The onhook voltage can be selected according to the line voltage depending on
the analog phone used. The low power/high power will increase/decrease the
output current. Selecting "low power" will make loop current limit = 20mA,
selecting "high power" make loop current limit = 32mA. The default selection
is 36V (High Power).
Select Polarity Reversal to adapt some call charge/billing system. Default is
"No".
This is the URI or IP address of the NTP (Network Time Protocol) server,
which the HandyTone ATA will use to synchronize the date/time.
If this parameter is set to "Yes", user ID will be sent as anonymous, essentially
blocks the Caller ID from displaying.
anonymous, essentially block the Caller ID from displaying. If it is set to "User
privacy header", the SIP INVITE message contains a "privacy" header, and the
server blocks the caller ID from the called party.
The duration of ringing when a call is not answered. Default is 60 seconds.
Default is Standard. Choose the selection to meet some special requirements
from Soft Switch vendors like Nortel, Broadsoft, etc.
