Field Description
SIP Transport
The TCP choice provides "guaranteed delivery", which assures that lost
packets are retransmitted. TCP also guarantees that the SIP packages are
received in the same order that they were sent. As a result, TCP overcomes
the main disadvantages of UDP. In addition, for security reasons, most
corporate firewalls block UDP ports. With TCP, new ports do not need to be
opened or packets dropped, because TCP is already in use for basic activities
such as Internet browsing or e-commerce. Options are: UDP, TCP, TLS. The
default is UDP.
SIP Port
Port number of the SIP message listening and transmission port.
The default is 5060.
SIP 100REL Enable
To enable the support of 100REL SIP extension for reliable transmission of
provisional responses (18x) and use of PRACK requests, select yes. Otherwise,
select no.
The default is no.
Auth Resync-Reboot
If this feature is enabled, the ATA device authenticates the sender when it
receives the NOTIFY resync reboot (RFC 2617) message. To use this feature,
select yes. Otherwise, select no.
The default is yes.
SIP Proxy-Require
The SIP proxy can support a specific extension or behavior when it sees this
header from the user agent. If this field is configured and the proxy does not
support it, it responds with the message, unsupported. Enter the appropriate
header in the field provided.
SIP Remote-Party-ID
To use the Remote-Party-ID header instead of the From header, select yes.
Otherwise, select no.
The default is yes.
SIP GUID
This field is not found in the PAP2T.
The Global Unique ID is generated for each line for each device. When it is
enabled, the ATA device adds a GUID header in the SIP request. The GUID is
generated the first time the unit boots up and stays with the unit through
rebooting and even factory reset. This feature was requested by Bell Canada
(Nortel) to limit the registration of SIP accounts.
The default is yes.
