Description
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.
Port number of the SIP message listening and transmission port.
The default is 5060.
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.
The external SIP port number.
If this feature is enabled, the WRP500 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.
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.
To use the Remote-Party-ID header instead of the From header,
select yes. Otherwise, select no.
The default is yes.
The Global Unique ID is generated for each line for each device.
When it is enabled, the WRP500 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.
