
[0] Disable (default)

[1] Enable
Enables secured SIP (SIPS URI) connections over multiple hops.

[0] Disable (default)

[1] Enable
When the SIPTransportType parameter is set to 2 (i.e., TLS) and the
parameter EnableSIPS is disabled, TLS is used for the next network
hop only. When the parameter SIPTransportType is set to 2 or 1 (i.e.,
TCP or TLS) and EnableSIPS is enabled, TLS is used through the
entire connection (over multiple hops).
Note: If this parameter is enabled and the parameter
SIPTransportType is set to 0 (i.e., UDP), the connection fails.
Enables the reuse of the same TCP connection for all calls to the
same destination.

[0] Disable = Uses a separate TCP connection for each call.

[1] Enable = (Default) Uses the same TCP connection for all calls.
Notes:

This parameter must be left at its default value (and not set to 0).

For the SAS application, this feature is configured using the
SASConnectionReuse parameter.
Enables the re-use of the same TCP/TLS connection for sessions with
the same user, even if the "alias" parameter is not present in the SIP
Via header of the first INVITE.

[0] Disable = (Default) TCP/TLS connection reuse is done only if
the "alias" parameter is present in the Via header of the first
INVITE.

[1] Enable
Note: To enable TCP/TLS connection re-use, set the
EnableTCPConnectionReuse parameter to 1.
Enables setting of all TCP/TLS connections as persistent and
therefore, not released.

[0] = (Default) Disable. All TCP connections (except those that are
set to a proxy IP) are released if not used by any SIP
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.
