This feature supports the configuration of the maximum size for each SIP message.
This allows the user to limit the size of the SIP message that is sent over the network.
The device rejects messages exceeding this user-defined size. The maximum SIP
message size is defined using the new parameter, MaxSIPMessageLength. The
maximum size can range between 1 and 50 Kbytes.

This feature provides a 30-second period (limit) for the receipt of a complete SIP
message on the device’s TCP socket. For example, if the device receives a SIP
message whose SIP Content-Length header is larger than the actual message body,
the TCP socket remains open and waits for the rest of the message body to arrive.
During this time, no other messages are accepted by the socket. However, if the
remaining message body does not arrive within 30 seconds, the device terminates the
session on the socket in order to allow new messages to arrive.
