DescriptionField
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.

the first time the unit boots up and stays with the unit through rebooting
and even factory reset.
Default setting: No
