'SIPS'
configure voip >

settings > 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 the parameter is enabled and the parameter
SIPTransportType is set to 0 (i.e., UDP), the connection fails.
'TCP/TLS Connection
Reuse'
tcp-conn-reuse
[EnableTCPConnectionR
euse]
Enables the reuse of an established TCP or TLS connection
between the device and a SIP user agent (UA) for subsequent
SIP requests sent to the UA. Any new out-of-dialog requests
(e.g., INVITE or REGISTER) use the same secured connection.
One of the benefits of enabling the parameter is that it may
improve performance by eliminating the need for additional
TCP/TLS handshakes with the UA, allowing sessions to be
established rapidly.
■ [0] Disable = The device uses a new TCP or TLS connection
with the UA.
■ [1] Enable = (Default) The device uses the same TCP or TLS
connection for all SIP requests with the UA.
Note:
■ For SIP responses, the device always uses the same
TCP/TLS connection, regardless of the parameter settings.
'Fake TCP alias'
configure voip >
sip-definition
settings > 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.
'Reliable Connection
Persistent Mode'
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.
