User's Manual 43. Configuration Parameters Reference
Parameter Description
[ReliableConnectionPer
sistentMode]
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
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.
Web: Use user=phone in
From Header
EMS: Is User Phone In
From
CLI: phone-in-from-hdr
[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
CLI: uri-for-assert-id
[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
CLI: tel2ip-no-ans-timeout
[IPAlertTimeout]
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.
The valid range is 0 to 3600. The default is 180.
Web/EMS: Enable GRUU
CLI: enable-gruu
[EnableGRUU]
Determines whether the Globally Routable User Agent URIs (GRUU)
mechanism is used, according to RFC 5627. This is used for obtaining a
GRUU from a registrar and for communicating a GRUU to a peer within a
dialog.
 [0] Disable (default)
 [1] Enable
A GRUU is a SIP URI that routes to an instance-specific UA and can be
