If set to "Yes", the device will ignore any SIP message that does not come from
the IP address (Source IP in the IP header) that it is registered to. Default
setting is "No".
Default is "No". If set to "Yes" the client will use DNS SRV to lookup for the
server.
If set to yes, a "user=phone" parameter will be attached to the "From" header in
SIP request.
This parameter decides whether the HandyTone ATA needs to send
REGISTER messages to the proxy server. The default setting is "Yes".
Default is "No". If set to "Yes", the device will first send registration request to
remove previous bindings.
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).
Default is "No". Use only if proxy supports 484 response.
Default is "No". When set to "Yes", the device still has a dial tone and allows
user make outgoing calls even if the device is not registered to the SIP proxy.
Sets the prefix added to each dialed number.
Default is 4 seconds.
This parameter allows 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. If set to "No", the "#" key will then
be included as part of the dialed string to be sent out.
This parameter defines the local SIP port the HandyTone ATA listens and
transmits. The default value is 5060.
This parameter defines the local RTP-RTCP port pair the HandyTone ATA
listens and transmits. 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.
Default "No". If set to "Yes", the device will pick randomly-generated SIP and
RTP ports. This is usually necessary when multiple HandyTone ATAs are
behind the same NAT.
