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 don't need to be opened or packets dropped for activities such as
Internet browsing or e-commerce.
Port number of the SIP message listening and transmission port.
Default setting: 5060 for PHONE1 and 5061 for PHONE2

If this feature is enabled, the ATA authenticates the sender when it
receives the NOTIFY resync reboot (RFC 2617) message. To use this
feature, select Yes. Otherwise, select No.
Default setting: 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.
Default setting: blank
To use the Remote-Party-ID header instead of the From header, select
Yes. Otherwise, select No.
Default setting: Yes
This feature limits the registration of SIP accounts. The Global Unique
ID is generated for each line for each ATA. When it is enabled, the
ATA 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.
Default setting: No
