This parameter controls whether the HandyTone ATA will attempt
to send an early INVITE each time a key is pressed when a user dials
a number. If set to "Yes", an INVITE is sent using the dial-number
collected thus far; Otherwise, no INVITE is sent until the "(Re-
)Dial" button is pressed or after about 5 seconds have elapsed if the
user forgets to press the "(Re-)Dial" button.
The "Yes" option should be used ONLY if there is a SIP proxy
configured and the proxy server supports 484 Incomplete Address
response. Otherwise, the call will most likely be rejected by the
proxy (with a 404 Not Found error).
Please note that this feature is NOT designed to work with and
should NOT be enabled for direct IP-to-IP calling.
This parameter allows the user to configure the "#" key to be used as
the "Send"(or "Dial") key. Once set to "Yes", pressing this key will
immediately trigger the sending of dialed string collected so far. In
this case, this key is essentially equivalent to the "(Re)Dial" key. If
set to "No", this # key will then be included as part of the dial string
to be sent out.
This parameter controls whether the HandyTone ATA needs to send
REGISTER messages to the proxy server. The default setting is
"Yes".
This parameter allows the user to specify the time frequency (in
minutes) the HandyTone ATA will refresh its registration with the
specified registrar. The default interval is 60 minutes (or 1 hour).
The maximum interval is 65535 minutes (about 45 days).
This parameter defines the local SIP port the HandyTone ATA will
listen and transmit on. The default value is 5060.
HandyTone ATA will listen and transmit on. It is the base RTP port
for channel 0. When configured, channel 0 will use this port_value
for RTP and the port_value+1 for its RTCP; channel 1 will use
port_value+2 for RTP and port_value+3 for its RTCP. The default
value is 5004.
This parameter, when set to Yes, will force random generation of
both the local SIP and RTP ports. This is usually necessary when
multiple HandyTone ATAs are behind the same NAT.
