SIP User's Manual

The device supports up to 100 simultaneous TLS sessions.
Defines the local UDP port for SIP messages.
The valid range is 1 to 65534. The default value is 5060.
Defines the local TCP port for SIP messages.
The valid range is 1 to 65535. The default value is 5060.
Defines the local TLS port for SIP messages.
The valid range is 1 to 65535. The default value is 5061.
Note: The value of this parameter must be different from the value of
the parameter TCPLocalSIPPort.
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 = Use a separate TCP connection for each call.

[1] Enable = Use the same TCP connection for all calls (default).
Enables setting of all TCP/TLS connections as persistent and
therefore, not released.

[0] = Disable (default) - 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.
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 value is 64*SIPT1Rtx
msec.
Defines the SIP destination port for sending initial SIP requests.
