SIP User's Manual 10. Configuration Parameters Reference
Parameter Description
stentMode]
dialog\transaction.
[1] = Enable - TCP connections to all destinations are persistent and
not released unless the device reaches 70% of its maximum TCP
resources.
While trying to send a SIP message connection, reuse policy
determines whether live connections to the specific destination are re-
used.
Persistent TCP connection ensures less network traffic due to fewer
setting up and tearing down of TCP connections and reduced latency on
subsequent requests due to avoidance of initial TCP handshake. For
TLS, persistent connection may reduce the number of costly TLS
handshakes to establish security associations, in addition to the initial
TCP connection set up.
Note: If the destination is a Proxy server, the TCP/TLS connection is
persistent regardless of the settings of this parameter.

The valid range is 0 to 3600. The default value is 180.
Web: Enable Remote Party
