
Unnamed bit 46, do not allow SIP IP and port redirection
There is information in a SIP request, where to send the response. In some cases,
especially in contact with NAT, this value is not set correctly. If this unnamed bit is
set, the AS55X does always send the response to that IP address and port, it receives
the request from.
Default value: Not set

Unnamed bit 47, use local username for SIP registration
If an authentication identity is entered for a SIP account, it will be used for
authentication for registration and call-setups. If this bit is set, for registration the
username is used as authentication identity.
Default value: Not set

Unnamed bit 48, get public IP address from register response

Unnamed bit 49, get public port from register response
In a NAT context, it might be possible to use the public IP address and port in the SIP
protocol as some SIP providers do only accept call-setups with the correct values.
With this bit the fetching of this information from the register response message can
be controlled.
Default value bit 48: Not set
Default value bit 49: Not set

Unnamed bit 50, abort SIP connection with TCP socket close
Normally, for a SIP connection it is not really necessary that the correspondent TCP
connection is up for the whole time. If this bit is set, the SIP connection will be
aborted, if the TCP port is closed.
Default value: Not set

Unnamed bit 52, allow registrar IP as proxy identity
In SIP client mode normally call setups are only accepted if they correspond to that
entity, the AS55X is registered at. A random number in the registration contact is
used to recognize the entity, but some providers do not handle this contact properly.
If this bit is set, it is sufficient, if the call setup arrives from the IP address of the
registrar.
Default value: Not set

Unnamed bit 55, FAX speed restriction
If this bit is set, FAX speed is limited to 4800bps. This setting only makes sense, if due
to bad line quality, the training procedures often gets very long.
Default value: Not set
