Parameter Description

The value of this parameter is also used by the SAS application as
the default transport layer for outgoing SIP calls.
Web: SIP UDP Local Port
EMS: Local SIP Port
[LocalSIPPort]
Defines the local UDP port for SIP messages.
The valid range is 1 to 65534. The default is 5060.
Web: SIP TCP Local Port
EMS: TCP Local SIP Port
[TCPLocalSIPPort]
Defines the local TCP port for SIP messages.
The valid range is 1 to 65535. The default is 5060.
Web: SIP TLS Local Port
EMS: TLS Local SIP Port
[TLSLocalSIPPort]
Defines the local TLS port for SIP messages.
The valid range is 1 to 65535. The default is 5061.
Note: The value of this parameter must be different from the value of
the parameter TCPLocalSIPPort.
Web/EMS: Enable SIPS
[EnableSIPS]
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.
Web/EMS: Enable TCP
Connection Reuse
[EnableTCPConnection
Reuse]
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.
Note: For the SAS application, this feature is configured using the
SASConnectionReuse parameter.
Web: Fake TCP alias
[FakeTCPalias]
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.
Web/EMS: Reliable
Connection Persistent
Mode
[ReliableConnectionPer
sistentMode]
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
