Parameter Description
Web/EMS: Enable TCP
Connection Reuse
CLI: tcp-conn-reuse
[EnableTCPConnectionReus
e]
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
CLI: 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
CLI: reliable-conn-persistent
[ReliableConnectionPersiste
ntMode]
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, pe
rsistent 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.
Web/EMS: TCP Timeout
CLI: tcp-timeout
[SIPTCPTimeout]
Defines the Timer B (INVITE transaction timeout timer) and Timer F
(non-INVITE transaction timeout timer), as defined in RFC 3261,
when the SIP transport type is TCP.
The valid range is 0 to 40 sec. The default is 64 * SipT1Rtx
parameter value. For example, if SipT1Rtx is set to 500 msec, then
the default of SIPTCPTimeout is 32 sec.
Web: SIP Destination Port
EMS: Destination Port
CLI: sip-dst-port
[SIPDestinationPort]
Defines the SIP destination port for sending initial SIP requests.
The valid range is 1 to 65534. The default port is 5060.
Note: SIP responses are sent to the port specified in the Via header.
Web: Use user=phone in SIP
URL
EMS: Is User Phone
CLI: user=phone-in-url
[IsUserPhone]
Determines whether the 'user=phone' string is added to the SIP URI
and SIP To header.
 [0] No = 'user=phone' string is not added.
 [1] Yes = (Default) 'user=phone' string is part of the SIP URI and
SIP To header.
