Parameter Description

[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
[ReliableConnectionPersi
stentMode]
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.
Web/EMS: 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 multiplied by the
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
[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
[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.
Web: Use user=phone in
From Header
EMS: Is User Phone In
From
[IsUserPhoneInFrom]
Determines whether the 'user=phone' string is added to the From and
Contact SIP headers.

[0] No = (Default) Doesn't add 'user=phone' string.

[1] Yes = 'user=phone' string is part of the From and Contact
headers.
Web: Use Tel URI for
Asserted Identity
[UseTelURIForAssertedI
D]
Determines the format of the URI in the P-Asserted-Identity and P-
Preferred-Identity headers.

[0] Disable = (Default) 'sip:'

[1] Enable = 'tel:'
Web: Tel to IP No Answer
Timeout
EMS: IP Alert Timeout Defines the time (in seconds) that the device waits for a 200 OK
response from the called party (IP side) after sending an INVITE
message. If the timer expires, the call is released.
